Abstract
A lock mechanism is provided in a head cover of a cylinder tube. The lock mechanism comprises a holder, which is installed in the head cover, a plurality of balls that are retained displaceably in a radial direction with respect to the holder, and a displacement member that displaces the balls under a resilient action of an elastic member. The balls engage with a ball groove of a lock pin. The balls are retained by a resilient force of the elastic member, in order to restrict displacement of the lock pin.
