Provided is a cylinder apparatus with which problems such as cost can be solved by simplifying an air vent structure and improving workability relating to assembly and machining, while maintaining air discharge performance. In a cylinder apparatus 1a, a front-side annular disc 40 is provided between a front-side end plate 4 and a cylinder 3, a cylinder-side opening 45 is provided to the front-side annular disc 40, a reservoir chamber-side opening 48, which communicates with the cylinder-side opening 45, is provided to the front-side annular disc 40, and rotation-restraining parts 27, 43 for restraining relative rotation are formed between the front-side end plate 4 and the front-side annular disc 40. The air vent structure is thereby simplified and workability relating to assembly and machining is improved while air discharge performance is maintained, which can contribute to reducing costs. |
