Abstract: PURPOSE:To accurately push back a male cone, by guiding an outer peripheral surface of a rim bar with a holder fixed to a grip coupler, and properly maintaining a press-fit condition of the rim bar. CONSTITUTION:A stop arm 12 has a hook portion 18, and the hook portion 18 is engaged with a grip coupler to retain a holder 11 at a fixed position. A rim bar 13 is formed at its outer circumference to be guided with a reverse stop projection 20 having a tapered surface 21. After a hook portion 19 is once pushed by the tapered surface 21 to a release position, it is engaged with a back surface of the projection 20 by a spring 14. Accordingly, a reaction to the reverse stop pawl is received by the holder, and a spring 5 is therefore compressed to accurately push back a male cone 4.
