CLUTCH DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/063054
Kind Code:
A1
Abstract:
A rotation translation part (40) has a shaft (41) and a nut (42). The shaft (41) rotates when torque from a rotary electric motor (30) is inputted. The cylindrical nut (42) is provided to the radially outer side of the shaft (41). When the shaft (41) rotates, translation causes the nut (42) to move relative to the shaft (41) in the axial direction. A fork (50) has a fork base (51) and movement restriction parts (501, 502). The cylindrical fork base (51) is provided to the radially outer side of the nut (42) and is capable of moving relative to the nut (42) in the axial direction. The movement restriction parts (501, 502) are capable of restricting the relative movement of the fork base (51) in the axial direction with respect to the nut (42). An electric actuator (20) is provided between the nut (42) and the fork base (51), the electric actuator (20) having a spring (201) that is capable of urging the fork base (51) in the axial direction in relation to the nut (42).
