<p><P>PROBLEM TO BE SOLVED: To provide a working vehicle which enables compact constitution in a radial direction of a hydraulic cylinder device for automatic braking, sharing a part by enhancing applicability of the hydraulic cylinder device to various kinds of working vehicles, and attains reduction of cost of the hydraulic cylinder device itself as well as reduction of cost of the whole working vehicle. <P>SOLUTION: When a steering angle of a front wheel exceeds a predetermined angle, the hydraulic cylinder device in the working vehicle for operating a rear wheel brake at an inner side in a turning direction of left and right rear wheels, has: a cylinder 71 of the hydraulic cylinder devices 12, 13; a piston 81 fitted so as to be projected from one end of the cylinder 71 and capable of being interlocked with an operation system of the rear wheel brake; and a cap 91 attached to the cylinder 71 so as to close the other end of the cylinder 71. An adaptor 101 for feeding an oil pressure to a hydraulic chamber between the cylinder 71 and the piston 81 is fixed to the cap 91 coaxially to the cylinder 71. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
