Claims

[Scope of utility model registration request]

In a vehicle, in order to switch the first shaft on the engine side and the second shaft on the wheel side in close contact to switch between an all-wheel drive state and a partial wheel drive state, a power contact is provided between the first shaft and the second shaft. and an operating mechanism for operating the contact between the first shaft and the second shaft by the synchronizing mesh mechanism, the operating mechanism having an operating end for operating the synchronizing mesh mechanism. a shift rail fitted to the shift rail and capable of moving along the shift rail in conjunction with an operating member; a shift lug fitted to the shift rail in series with the shift lug and configured to move the shift lug as the shift lug moves; and a coil spring that applies a biasing force to the rail, and the coil spring is loaded between a first engaging part and a second engaging part formed in the shift rail, and the shift lug is loaded between a first engaging part and a second engaging part formed in the shift rail. When the shift rail is biased by movement in one direction, one end of the coil spring is engaged with the first retaining portion, and the coil spring is connected to the first engaging portion and one end of the shift lug. and the other end of the coil spring is configured to be compressed between the coil springs and the second retaining portion of the shift rail when the shift rail is biased by movement of the shift lug in the other direction. A driving wheel number switching device for a vehicle, characterized in that a movable engagement member capable of engaging with one end of the coil spring and the other end of the shift lug is provided to compress the coil spring.
