MOBILE VEHICLE

To provide a mobile vehicle capable of facilitating an exchange work of a rotary shaft, a front universal joint, and a rear universal joint.SOLUTION: A front universal joint 27 is spline engaged to an output shaft 16 at a first engagement length L1, and is spline engaged to a rotary shaft 24 at a second engagement length L2. A rear universal joint 28 is spline engaged to the rotary shaft 24 at a third engagement length L3, and is spline engaged to an input shaft 45 at a fourth engagement length L4. The rotary shaft 24 is moved rearward with respect to the rear universal joint 28, and then the engagement length of the rear universal joint 28 with respect to the rotary shaft 24 is made longer than the third engagement length L3, and thus the front universal joint 27 is detached from the output shaft 16.SELECTED DRAWING: Figure 3 【課題】作業車において、回転軸、前自在継手及び後自在継手の交換作業が容易に行えるように構成する。【解決手段】前自在継手２７が、出力軸１６に対して第１係合長さＬ１でスプライン係合され、回転軸２４に対して第２係合長さＬ２でスプライン係合される。後自在継手２８が、回転軸２４に対して第３係合長さＬ３でスプライン係合され、入力軸４５に対して第４係合長さＬ４でスプライン係合される。回転軸２４が後自在継手２８に対して後向きに移動されて、後自在継手２８の回転軸２４に対する係合長さが第３係合長さＬ３よりも長くされ、これに伴って前自在継手２７が出力軸１６から抜け外れる。【選択図】図３
