A spider is screwed to a drive shaft, includes a first screw that advances in one direction of an axial direction of the drive shaft when the spider rotates relative to the drive shaft in one direction of a circumferential direction, and is fastened to the drive shaft by the first screw. A nut is screwed to the drive shaft, includes a second screw that advances in the other direction of the axial direction of the drive shaft when the nut rotates relative to the drive shaft in one direction of the circumferential direction, and is fastened to the drive shaft by the second screw.

Continuously variable transmission

A drive switching mechanism of a utility vehicle includes: a two-wheel drive and four-wheel drive switching device that switches between two-wheel drive and four-wheel drive of the utility vehicle; and a control unit that controls the drive switching mechanism. The two-wheel drive and four-wheel drive switching device switches between two-wheel drive and four-wheel drive by using a first clutch. The control unit permits the two-wheel drive and four-wheel drive switching device to switch from two-wheel drive to four-wheel drive when a rotation difference of the first clutch becomes equal to or smaller than a predetermined value.

Drive switching mechanism of utility vehicle

A shift switching mechanism of a utility vehicle includes: an input gear connected to an input shaft to which a driving force of an engine is input; a shifter that is connected to a counter shaft transmitting a driving force of the input shaft, and enables engagement between the input gear and a gear connected to the counter shaft; and a control unit that controls the shift switching mechanism. At reception of a shift command, the control unit calculates a rotation difference between the input gear and the shifter, and controls output of the engine to reduce the rotation difference.
