PURPOSE:To prevent a register ring from rotating due to contact, etc., with another body during diving operation, by providing a control member, which either stops the falling of the click part of a click spring or release it, under the click part. CONSTITUTION:A register ring 7 is fitted rotatably in an annular groove 10 where the lower part of its ring 9 is formed at the upper external circumference of a side 1, and on the groove bottom of the annular ring 10, a click spring 14 is provided. At the tip part of the click spring 14, a click part 15 is formed by extrusion, and this click part 15 is engaged with the engagement part 13 of the register ring 7. Then, the click part 15 selects its falling stop position and releasing position by the positioning spring 28 of a rotor 22. Consequently, the register ring is prevented from rotating due to contact, etc., with another body. |
