<p>A damper main body (30) that moves telescopically according to external input has a ball-screw mechanism (16) that converts the telescopic movement to rotation movement and comprises a ball nut (17) and a screw shaft (18). A motor (32) is provided coaxially with the damper main body (30). The motor (32) produces electromagnetic resistance force that opposes rotation movement applied to a rotation shaft (6) of the motor. The screw shaft (18) and the rotation shaft (6) are integrally formed as a shaft member. Damping force according to electromagnetic force of the motor (32) is generated as the damper main body (30) moves telescopically.</p> |
