When the rod guide 10 is fixed on the cylinder 1, the cylinder lower end 1A is curled to make an inner periphery abut on the protrusion 13, and the inner periphery of the cylinder end is not exposed to the air. Therefore, moisture is not collected in the inner periphery of the cylinder end to prevent the formation of rust. |
