Abstract
A release device for a clutch including a cylinder aligned coaxially with a release bearing, a cylindrical piston adapted to fit in a cylindrical operation chamber of the cylinder, and an annular packing mounted adjacent an annular end of the piston within the operation chamber, the operation chamber being connected to an external operating pressure control device through a liquid pressure control passage, the piston being axially connected, at its one end positioned outside the operation chamber, to the release bearing, wherein an annular slide member is fixed to an end of the packing which adjoins the piston, the slide member being greater in hardness than the packing and lower in friction coefficient against the piston than the packing.
