A cylinder apparatus (10) has: a cylinder (11) in which a working fluid is sealed; a piston (25) which is slidably fitted inside the cylinder (11), the piston (25) dividing a first chamber (28) and a second chamber (29); a piston rod (31) linked to the piston (25); an outer tube (13) provided to the outer periphery of the cylinder (11), the outer tube (13) forming a reservoir chamber (12) in which the working fluid and a working gas are sealed between the outer tube (13) and the cylinder (11); and a base member (20) provided to a first end part of the cylinder (11), the base member (20) dividing the second chamber (29) and the reservoir chamber (12) inside the cylinder (11), the outer tube (13) being provided with a protrusion (91) formed by elastic deformation, the protrusion (91) protruding in an annular shape toward the cylinder (11). |
