摘要： PROBLEM TO BE SOLVED: To provide an on-snow bicycle which does not spoil ski-feeling on the snow and is excellent in traveling performance. SOLUTION: A sled plate 2 is fitted in place of a front wheel of a bicycle, and a wheel-shaped sled 3 is fitted in place of a rear wheel. The wheel-shaped sled 3 is of the structure where a plurality of sleds of the same shape are arranged in a circumference, and when not in rotation, the wheel-shaped sled plays a role similar to that of a regular sled plate. When in rotation, a V-shaped rear part 6 is bitten in snow, and pushes the snow backward to obtain the propulsion. A gear 7 is fixed to an axle of the wheel-shaped sled 3 to agree the rotational direction of a pedal with the rotational direction of the wheel- shaped sled 3. The propulsion is obtained by stepping on the pedal. After the advancing speed is obtained, the pedal is stopped, and the skiing on the snow can be enjoyed with the wheel-shaped sled 3 forming a regular sled.

摘要： PROBLEM TO BE SOLVED: To make an operation lever follow the movement of the finger of a driver when the driver rotates a handle bar and to improve the operability by providing the front end part of the operation lever of a throttle lever device vertically rockable to a throttle lever bracket. SOLUTION: When the fingers of a driver are caught on an operation lever 3 in the state where a grip 8 is held in the hand to pull it to the driver side, the operation lever 3 and a drive arm 11 are integrally rotated around a support shaft 4 to pull a throttle wire 6, whereby the fuel feed quantity to an engine is increased to increase the rotating speed. When the driver turns a handle bar 7 to the left or right in this state, the touching state of the driver's fingers to the operation lever 3 is vertically changed. However, since the operation lever 3 is supported by the shaft 11a of the drive arm 11, the operation lever 3 follows the movement of the driver's fingers and rotates with a proper moderation feeling by the engagement of a ball 15 with a groove 11d, and satisfactory operability can be provided.

摘要： PURPOSE:To reduce the ground load of a front part so easily at time of travel ing on a soft road surface or the like by changing a longitudinal load distribu tion with the weight movement of a rider. CONSTITUTION:In a traveling vehicle, having a steering part 16 in front of a car body 11, supporting a driver 18 pivotally on a rear part of the body 11 free of rocking motion, and a cushion unit 24 is interposingly installed between the driver 18 and the body 11, while installing a power unit 17 to be power-transmittably connected to the driver 18 in the more front than a pivotally supporting part of the driver 18 to the body 11, a boarding part 11a, where a driver is boardable, is formed in the car body 11. This boarding part 11a is installed extendedly in the more rearward than a line L1 connecting a grip part 14a of a steering handle 14 to a rearmost grounded point of the driver 18, thereby forming an almost flat foot rest part 77, and the cushion unit 24 is connected to the car body 11 in the more front than the this line L1.

摘要： PURPOSE:To improve the riding comfortableness, by arranging two engaging positions for a torsion spring. CONSTITUTION:One end of the torsion spring 16 is engated with an under edge of a side wall of a truck housing 2 to constitute a fixed side end 16a, and the other end extends to a sliding rail 8 and engages with the rail 8 to constitute a movable side end 16b. The torsion spring 16 forces down the sliding rail 8 by its resiliency to provide the truck 7 with a cushioning force and a forace to contact with the snow. In this suspension, to displace the engaging position of the movable side end 16b of the torsion spring 16 from its intermediate position over the slide rail 8 to the bearing side of the spring 16, two engaging members 18 are provided. Thus, according to the larger of little displacement, enough cushioning effect can be obtained.
