To provide a cylinder device which enables reduction of costs and can inhibit influence of deformation caused by welding.SOLUTION: A cylinder device 11 has: an inner cylinder; a piston which is slidably provided in the inner cylinder; an outer cylinder 16 which covers an outer periphery part of the inner cylinder; and a bracket 101 fixed to an outer periphery part of the outer cylinder 16 by projection welding. At the outer periphery part of the outer cylinder 16, an attachment part 125 to which a mating component 131 is attached is provided adjacent to the bracket 101 in an axial direction of the outer cylinder 16. In the bracket 101, welding projection parts 121 fixed to the outer cylinder 16 by projection welding are provided offset to the opposite side of the attachment part 125 in the axial direction of the outer cylinder 16.SELECTED DRAWING: Figure 2
