Abstract
An air cylinder having a simple and effective configuration to reduce the axial length and provide ease of processing. A sliding bearing that guides a piston rod is disposed at a position adjacent to a groove in which a rod packing is fitted. One end of the sliding bearing serves as the side wall of the groove and prevents displacement of the rod packing. The other end of the sliding bearing extends so as to cover part of a yenta of a first port. An orifice having a sectional area smaller than that of the yenta is formed at the position of the yenta by the sliding bearing.
