摘要

A stroke length adjusting device which can be applied to a mechanism for converting a rotary motion into a reciprocating motion is disclosed. The device comprises two oil pressure chambers communicated through a bore with each other and a crank arranged between these two oil pressure chambers. A pressure balance between the two oil pressure chambers permits the crank to displace in its axial direction so as to adjust a stroke length of the reciprocating motion.
