PROBLEM;The present invention relates to a tubular shock absorber including a tubular case protruding from a side of a main body portion of the shock absorber. An object of the present invention is to prevent a foreign object such as water and dust from entering toward a screw portion of the case.;MEANS FOR SOLVING;A piston 5 with a piston rod 6 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 a movement of the piston 5 with use of a damping force generation mechanism 25. The damping force generation mechanism 25 is contained in a cylindrical case 26 protruding from a side of an outer tube 3, and the damping force generation mechanism 25 is fixed by threadably attaching a nut member 34 to a male screw portion 50 of the case 26. An O-ring is disposed between an outer circumferential surface of the case 26 and an inner circumferential surface of the nut member 34 to seal an uncoated male screw portion 50 from the outside. As a result, it is possible to prevent water, dust, and the like from entering toward the uncoated male screw portion 50 to prevent rust and corrosion from being formed thereon. |
