Abstract: The present invention is a shift device for switching a dog clutch mechanism in a transmission, comprising: a shift shaft capable of moving in an axial direction; a shift member capable of moving in the axial direction within a predetermined waiting stroke range; an elastic member holder for a waiting mechanism; and an elastic member provided in outside of the shift shaft in a radial direction so as to be compressed and expanded between the elastic member holder and the shift member, wherein the elastic member biases the shift member toward one side in the axial direction.

Abstract: An engine and a transmission are connected to each other via a connecting bracket interposed therebetween in the vehicular lengthwise direction. The engine is provided with a first connector having a first mounting hole substantially parallel to a vehicle lengthwise direction, and a first tightening member to be inserted into the first mounting hole on a side opposite to the engine connects the first end of the connecting bracket to the first connector. The transmission is provided with a second connector having a second mounting hole penetrating in a vehicular widthwise direction, and a second tightening member to be inserted into the second mounting hole connects the second end of the connecting bracket to the second connector.

Abstract: A utility vehicle 1 prevents a size increase of a transmission while ensuring a predetermined inter-shaft distance between an output shaft and a rear axle. The utility vehicle 1 is capable of switching a two wheel drive mode for transmitting drive force to rear wheels 3 and a four wheel drive mode for transmitting the drive force to front wheels 2 and the rear wheels 3, a transmission 9 includes an input shaft 92 to which the drive force from an engine 8 is inputted, a front wheel drive output shaft 94 for transmitting the drive force of the input shaft 92 to the front wheels 2, and a rear axle 96 for transmitting the drive force of the input shaft 92 to the rear wheels 3. A rear wheel drive output shaft 95 is provided in a motive power transmission route between the front wheel drive output shaft 94 and the rear axle 96.
