Abstract
A tubular shock absorber including a tubular case protruding from a side of a main body portion of the shock absorber. A piston () with a piston rod () coupled thereto is inserted in a cylinder sealingly containing oil, and a damping force is generated by controlling a flow of the oil generated by movement of the piston with use of a damping force generation mechanism (). The damping force generation mechanism is contained in a cylindrical case () protruding from a side of an outer tube (), and the damping force generation mechanism is fixed by threadably attaching a nut member () to a male screw portion () of the case. An O-ring is disposed between an outer circumferential surface of the case and an inner circumferential surface of the nut member to seal an uncoated male screw portion from the outside.
