摘要：
A fluid cylinder with a swivel joint which is more improved with high utility is provided. To this end, in the fluid cylinder, a flow passage (R2b) leading to a chamber (1F) at the rod side of the cylinder is provided inside a rod (3), and a pin hole (3H) in a rod front end portion (3F) and a pin (P1) fitted in the pin hole (3H) are formed into a swivel joint so that the flow passage (R2b) is always guided to an outside even if the pin hole (3H) and the pin (P1) are relatively rotated.
