記載の四輪駆動切換装置。[Claims for Utility Model Registration] 1. A clutch plate is interposed between the drive source and the rear drive shaft, and driving torque is transmitted to the rear drive shaft by pressing and engaging the clutch plate with a piston. In a four-wheel drive switching device, a sleeve disposed opposite to the piston and slidable in a direction in which the piston presses a clutch plate and in a direction in which the piston moves away from the clutch plate, an electric motor, and a sleeve between the electric motor and the sleeve. A four-wheel drive switching device comprising: an interposed slide member that slides the sleeve in both directions by rotational torque from an electric motor. 2. Claim 1, wherein the sliding member is a helical gear that meshes with an internal threaded portion formed on the inner peripheral portion of the sleeve and is rotated by an electric motor.
Four-wheel drive switching device as described.
