Shock absorber

A shock absorber including:

• a cylinder;
• a piston provided inside the cylinder to be slidable;
• and
• a piston rod connected to the piston,
• the shock absorber comprising:
• a first movement suppression part provided in a cylindrical part of the cylinder and protruding outward in a radial direction;
• a spring receiving member including a cylinder-shaped cylindrical part covering at least a part of the cylinder, and a seating part on which a suspension spring is seated, and configured to be in contact with the first movement suppression part to suppress relative movement in an axial direction with respect to the cylinder;
• and
• a second movement suppression part in contact with an outer circumferential surface of the cylinder and the cylindrical part to suppress relative movement in a
• circumferential direction between the cylinder and the spring receiving member,
• wherein the spring receiving member has a communication part provided in the cylindrical part to allow communication between an outer circumferential surface of the cylinder and an outer circumferential surface side of the cylindrical part,
• wherein the communication part is a groove part formed in a notch shape from an axial end surface of the cylindrical part,
• wherein a protruding part protruding radially outward is formed on an axial end surface of the groove part, and
• wherein axial movement of at least a part of a dust cover, which covers at least a part of the cylinder or at least a part of the cylindrical part, is suppressed by the protruding part.

• wherein the second movement suppression part has a stepped part formed so that a part of an outer circumferential surface is stepped, and
• wherein axial movement of at least a part of a dust cover, which covers at least a part of the cylinder or at least a part of the cylindrical part, is suppressed by the stepped part.
