Vehicle suspension

Abstract

A suspension (S) for a vehicle (1) includes a rod-shaped torsion spring (3), an arm (2), a motor (M), and a deceleration unit (G). The torsion spring (3) is rotatably supported by the vehicle (1). The arm (2) extends in a front-rear direction of the vehicle (1) and swingably supports a wheel of the vehicle (1) by using biasing force of the torsion spring (3). The motor (M) is fixed on a side of the vehicle (1). The deceleration unit (G) decelerates rotation of the motor (M), and rotationally drives the torsion spring (3) or a swing shaft (2a) of the arm (2). An output shaft (Z2) of the deceleration unit (G) is provided coaxially with the torsion spring (3) or the swing shaft (2a).
