輌。[Claims for Utility Model Registration] The front wheels 1 and the rear wheels 2 are configured to be drivable, and
A speed increase switching mechanism B is interposed between the front wheel drive shaft 14 and the front axle case 21 so that the speed can be freely changed between constant speed and increased speed. In a front wheel steering vehicle equipped with a speed increasing switching mechanism configured to operate the operating mechanism C of the speed switching mechanism B, a steering gear box 55 connected to the steering mechanism D is provided with a steering gear box 55 that is configured to operate the operating mechanism C of the speed switching mechanism B. A steering operating gear 58 that rotates in the opposite direction is provided, and operating protrusions 61, 61 are provided on the steering operating gear 58.
At the same time, a front and rear sliding body 62 connected to the operating mechanism C of the speed increase switching mechanism B is provided, and the front and rear sliding body 6
2, an engaging protrusion 6 that engages with the operating protrusions 61, 61 in conjunction with forward and reverse rotation of the steering operating gear 58;
3 and 63, and elastic means 6 at the lower part of the front and rear sliding bodies 62 for pressing the front and rear sliding bodies 62 upward.
Further, on the upper part of the front and rear sliding body 62, there is a push-down means 68 that presses the front and rear sliding plate 62 in a downward direction in conjunction with the front wheel speed increasing operation lever 74.
1. A front wheel steering vehicle equipped with a speed increase switching mechanism, characterized in that the engagement between the steering operating gear 58 and the front and rear sliding bodies 62 can be released by positioning the steering gear 58 and the front and rear sliders 62.
