Vehicle damper

A vehicle damper, comprising:

• a movable member that moves with linear motion according to a load applied from a wheel;
• a conversion member that converts the linear motion of the movable member into rotational motion;
• an electric motor having a rotor that rotates in conjunction with the rotational motion converted by the conversion member;
• a motor housing that houses the electric motor;
• and
• a damper mount housing that is fixed to a vehicle body and connected to the motor housing via a first elastic member, wherein
• the conversion member is constituted of a ball screw and a ball screw nut, the ball screw being provided in the movable member, the ball screw nut being threadedly engaged with the ball screw,
• the vehicle damper dampens the linear motion of the movable member by an electromagnetic force of the electric motor,
• the movable member comprises
• an outer cylinder including a connecting part that has one end to be connected to the wheel,
• a first inner cylinder housed in the outer cylinder and extending in an axial direction of the outer cylinder, and
• a second inner cylinder housed in the outer cylinder, housing herein the first inner cylinder, and having one end connected to the motor housing,
• the motor housing has an impact-absorbing member attached to an edge of one end of the motor housing, the impact-absorbing member surrounding an outer periphery of the second inner cylinder and facing one end of the outer cylinder, and
• the vehicle damper has a second elastic member that is provided for at least one of the motor housing or the damper mount housing and abuts on the other of the motor housing or the damper mount housing when a load is applied and the motor housing and the damper mount housing approach each other.
