More Information
Summary:The present invention reduces the sliding resistance of a push rod part with respect to a piston rod part and thus improves the movability of the push rod part. A push rod part 12 has a valve member 13 that opens and closes a communication path 9 communicating between an upper oil chamber B and a lower oil chamber C formed in a cylinder 2. In the push rod part 12, the lower end of a rod member 14, which is the end opposite from a piston 7, is formed to serve as a cap member 15 and is thus formed of a resin material.
