PURPOSE:To improve the click sense of a rotary bezel by forming the center part and the rear end of a click projection to a column, and forming the tip which is in contact with a click groove to a hemisphere. CONSTITUTION:When a coil spring 12 and a click projection 13 are inserted into a side hole 10a, and a pipe 14 is fitted loosely into the side hole 10a so as to cover time, the pipe 14 also moves up and down together with the clock projection 13 by the spring pressure of the coil spring 12. Therefore the clock projection 13 can move freely upward and downward, by which backlash in the upper and lower directions of a rotary bezel 11 is absorbed. Also, the clock projection 13 is always supported by the pipe 13, by which the generation of backlash in the rotational direction of the rotary bezel 11 is prevented and the smooth and exact click operating sense can be obtained.
