Abstract:
PROBLEM TO BE SOLVED: To provide a detachable mechanism for a rotatable annular grooved leveling roller around a spindle.
SOLUTION: A spindle (1) has an air space (4) into which a pusher (9) is inserted, and the pusher (9) has tapered thrust surfaces (9a, 9b) which displace a holder member (8) from a released position to a fixed position with a spring (10) force. The holder member (8) is arrange in the opening section provided in a wall section (3) of a tubular space (4). A plunger (11) connected to the pusher (9) works to transfer the pusher (9) to the predetermined position in the teeth of the spring (10) force.
