1. A suspension device comprising:
a cylinder configured to store fluid therein; a piston configured to divide an inside of the cylinder and arranged to be capable of sliding on the inside of the cylinder; a piston rod configured to support the piston and including a projecting part that projects from one end of the cylinder to an outside of the cylinder; an elastic member provided around the projecting part of the piston rod; a transmitting member including a first member provided around the projecting part of the piston rod and provided further on a cylinder side than the elastic member in an axis direction of the piston rod and a second member provided around the projecting part of the piston rod and provided on an opposite side of the first member across the elastic member in the axis direction, the transmitting member configured to hold the elastic member from both sides in the axis direction with the first member and the second member and transmit a shock received by the piston rod to the elastic member; a supporting member, which is a cylindrical member inserted into the elastic member, configured to support the projecting part of the piston rod, arranged to be held between the first member and the second member in the axis direction to set a distance in the axis direction between the first member and the second member to a predetermined distance, and pressed by the transmitting member when the first member or the second member receives a shock from the piston rod; and an attachment member attached to a vehicle body side, wherein the elastic member includes a restricting mechanism configured to restrict the first member from being displaced with respect to the elastic member in a state in which the piston rod is not arranged inside the elastic member and the first member, the first member is fixed around the projecting part in the piston rod in a state in which the piston rod is arranged inside the first member, the elastic member includes a first elastic body arranged further on the cylinder side than the attachment member, and a second elastic body provided separately from the first elastic body and provided on an opposite side of the first elastic body across the attachment member, and the first elastic body is configured to contact the second member. |
