摘要： PURPOSE:To suppress speed increase in a car caused externally by furnishing an intermediate shaft for transmitting the power from a transmission system through a mechanism, which converts the rotational power into uneven speed rotation, and a flexible mechanism which admits advance and delay of the rotational power, and restraining this intermediate shaft with change in the rotary phase of a race an retainer resulting from accelerated rotation from a running direction device. CONSTITUTION:When a higher rotating speed than the rotating speed of an input shaft 4 is applied from a running direction device 3, a rotary phase difference is generated between a retainer 17 and race 18, and a pinching member 19 pinches an intermediate shaft 12 to hinder speed increase in the running direction device 3. In this condition, the pinching member 19, retainer 17, race 18 are put in a single piece, so that the rotational power to the running direction device 3 will not sink below the rotating speed of the input shaft 4. Power from No.1 clutch 5 is transmitted to the intermediate shaft 12 through an uneven speed transmission mechanism 8, so that rotation of the intermediate shaft 12 takes advance and delay repetitively with the rotation of retainer 17 as reference, and the pinching member 19 is released from pinching at the timing of this delay, which allows the checked condition to be released in a short time.

摘要： PURPOSE:To keep the weight balance of a machine body and to construct a riding mower with small number of parts by placing a mowing apparatus having longitudinal shaft between front wheels and back wheels and placing a driver's seat above the mowing apparatus. CONSTITUTION:A blade 4 and a grass-collector 5 of a mowing apparatus A are placed between the front and rear wheels 1 and 2 and the lawn mowed with the blade 4 is transferred by the ascending air flow into an opening 5a at the upper part of the grass collector 5. Even if the grass collector is fully packed with the mowed grass, the weight balance of the machine body is maintained in desirable state. A duct for transferring mowed grass becomes unnecessary. A driver's seat 3 is attached to the upper surface of the mowing apparatus to eliminate the parts for holding the driver's seat.

摘要： PURPOSE:To simplify structure of a grass collecting device without damaging merits of arranging the grass collecting device above a blade and to relatively readily enlarge grass collecting volume, by constituting the structure of the grass collecting device in such a way that an air flow from the blade is sent through a channel at the outside of the grass collecting device toward the upper part. CONSTITUTION:Grass reaped by a blade 3 is sent together with an air flow from the blade 3 through an annular space S between the outside of a grass collecting device 12 and a cylindrical member 13 toward the top, introduced to an opening part 12a of the grass collecting device 12 by a guide member 14 and dropped in the interior of the grass collecting device 12. The grass collecting device 12 can be manufactured in any shape and dimension in a state wherein the grass collecting device 12 is contained in the cylindrical member 13.

摘要： PURPOSE:To enable a rapid starting operation without need for particularly providing a clutch for the purpose by providing a clutch operating valve mechanism for operating switchover to a clutch engaging condition and a clutch disengaging condition while providing the artificially operating tool of the clutch operating valve mechanism. CONSTITUTION:By steppingly operating a pedal in the maximum step-in position, as a clutch operating valve mechanism V2 is switched over to the disengaging condition of a clutch C2, an operating oil chamber 30 is connected to a tank T releasing the pressurization of a hydraulic piston 29 by a pressure oil to disengage the clutch C2. When the clutch operating valve mechanism V2 is switched over to the engaging condition of the clutch C2, the connection between the operating oil chamber 30 and the tank T is cut off while an oil-pressure control valve mechanism V1 feeds oil into the operating oil chamber 30 in the maximum pressure controlling condition, rapidly carrying out the pressurization of the hydraulic piston 29 by a pressure oil to suddenly engage the clutch C2. That is, the rapid engaging operation of the traveling friction clutch C2 can be carried out regardless of the existence of the oil-pressure control valve mechanism V1 to enable the rapid starting operation of a machine body.

摘要： PURPOSE:To prevent the occurrence of bad connection and to make the above structure in a compact size by forming a sliding spool of a sequence valve for operating a speed change clutch separately from a piston of a hydraulic cylinder. CONSTITUTION:As hydraulic cylinders 18, 20 operate for releasing the engagement of a shift gear, transmission portions 42a, 42b, 48a, 48b are operated to the side separating from receiving portions 42c, 48c by the cylinder operation. Sequence valves 41, 47 are switches from the clutch-on position to the clutch-off position by urging force of spring S3, S4, whereby a speed change clutch is switched from connection state to disconnection state. As the hydraulic cylinders 18, 20 operate the shift gear to the engagement position, the transmission portions 42a, 42b, 48a, 48b are forced to press the receiving portions 42c, 48c by the above cylinder operation, so that the sequence valves 41, 47 are switched from the clutch-off position to the clutch-off position to switch the speed change clutch from the disconnection state to the connection state.

摘要： PURPOSE:To improve handleability of cord drawing property, by making a draw stopping member to be operated to a suspension release side by centrifugal force act on a suspension operation side by centrifugal force applied to a cord. CONSTITUTION:When a cord 7 is cut and shortened, frictional force to engage a hook part 11a of a draw stopping member 11 with gear parts 9a and 10a is lessened and centrifugal force to act on the draw stopping member 11 overcomes the frictional force. The hook part 11a comes out of the gear parts 9a and 10a to the outside, cord reels 9 and 10 become a freely rotatable state based on a cord case 8 and the cord is drawn out up to length where centrifugal force to act on the draw stopping member is balanced with centrifugal force applied to the cord.

摘要： PURPOSE: To improve the durability of a pilot pressure valve by forming grooves for relieving pilot pressure in the longitudinal direction of a piston rod and synchronizing the operation of a shifter to an untransmissive condition with the disconnecting operation of a clutch.
CONSTITUTION: A groove 26 is formed on a piston rod 19 in a form extended in the longitudinal direction, in such a way that when a shifter (a) is slided a little from a speed change position to a neutral position, both ports 25 are connected to a drain space D through a groove 26, starting the relief of pilot pressure. Thereby, sufficient time for relieving the pilot pressure can be provided before the shifter (a) comes to the neutral position, without causing delay in the disconnecting operation by a clutch due to the time required for relieving the pilot pressure, with respect to the operation of the shifter (a) into the neutral position.
