摘要： PURPOSE:To realize the safe driving of the moving car by providing a mechanism for lowering the maximum driving speed of the traveling part due to an automatic speed change control mechanism the smaller the set rotational speed of an engine is in accordance with the change in the set value of the engine rotational speed. CONSTITUTION:A belt type stepless speed change device 6 consisting of an input split pulley 6A and an output split pulley 6C, in which the effective diameter change is operable, is interposed in a transmission system from an engine 3 to a crawler type traveling part 5. An automatic speed change control mechanism 2 is constituted by providing a controller 11 which compares the detected value of an operating quantity detector 7 of a speed change operating lever 1 with that of a driving speed detector 8 of the traveling part 5 and actuates a valve 10 with respect to the effective diameter changing cylinder 9 of an input pulley 6A. In this case, there is provided a mechanism 4 for defining the speed change operation of the control mechanism 2 further so that the traveling part driving speed matched to the operating quantity of the lever 1 is automatically lowered as the detected value of an engine rotational speed detector 12 becomes smaller.

摘要： PURPOSE:To exchange wires rapidly and easily, by contact connecting a wire end portion to a reel-like portion material in holding and demounting-free shapes under a fixed condition, by forming the wire end portion in a shape that the end portion is freely inserted into and detached from a wire inserting port and by mounting a rotation range regulating mechanism of the reel-like portion material. CONSTITUTION:This structure is constituted in such a manner that a shaft-like connecting-pin 15 fastened to an end portion of an inner wire 7a is contact connected to a notch portion 16 of a reel- like portion material 6 in holding and demounting-free shapes by motion in the diameter direction, and the connecting-pin 15 is freely connected and detached from the outside of a case 3 to the reel- like portion material 6 in a contact connecting portion only when the contact connecting portion coincides in the circumferential direction to a wire inserting port 17 of the case 3. Thus, a stopper 18 for regulating a turn range of the reel-like portion material 6 is unfastened, the contact connecting portion and the wire inserting port 17 are adjusted in the circumferential direction, the inner wire 7a is pulled and the connecting-pin 15 is separated from the notch portion 16 and taken out from the wire inserting port 17. The connecting-pin is connected in accordance with procedure reverse to demounting procedure.

摘要： PURPOSE:To evade securely a forward/back movement change-over with a clutch left unclutched by mistake, by constituting a mechanism, restraining the motion of an control lever in the forward/backward movement change-over direction so that the restraint can be released by interlocking with the disengagement of a main clutch. CONSTITUTION:Mechanism 3 is provided which lays restraint on the forward/backward change-over operation of lever 1 by projecting restraint plate 3A toward forward/backward change-over guide groove part 8C, coupling guide groove part 8A guiding the variable speed slide of lever 1 in a forward change-over state with guide groove 8B guiding the variable speed slide of lever 1 in a backward change-over state, and releases the restraint by drawing restraint plate 3A. Further, a linking mechanism is provided which restrains and releases mechanism 3 automatically and reversibly interlocking with the change-over operation of operating pedal 14 for main clutch 4 in front of variable speed gear A and change-over mechanism 2 in terms of transmission sequence.
