Claims

[Scope of utility model registration request]

In a four-wheel drive vehicle having a reciprocating fork shaft to which a shift fork for reciprocating a two-wheel/four-wheel switching slider is fixed, rotating torque is applied to an output shaft that drives the fork shaft via a torsion spring. A worm wheel is provided to be rotated by a motor via a worm gear, a cam switch for detecting the rotation angle is provided in proximity to the worm wheel, and a protrusion that surrounds the outer periphery of the cam switch and is in contact with the worm wheel, A two-wheel/four-wheel drive switching device characterized by being provided in a casing surrounding the worm wheel.
