Abstract
A hydraulic operating apparatus includes a release hub for supporting a release bearing, a piston formed separately from the release hub, and an abutting plate disposed between the piston and release hub as a power transmission relay member for absorbing shocks. The abutting plate may itself be formed of an elastic material or may include an elastic element to suppress shocks transmitted between the piston and release hub. The release hub and piston are formed annular, and the release hub is supported slidable on an outer surface of an outer wall section of a cylinder defining an annular piston chamber. The release hub includes a supporting surface having a smaller diameter than the outer wall section for supporting the release bearing.
