を配置しなければならない問題もあった。However, in a conventional member holding structure as shown in the drawing, the flanged pin 2 has a stepped portion 2a and has a complicated shape which is difficult to machine. In addition, there is a problem that the date wheel holder 1 is easily deformed by the load applied when the flanged pin 2 is press-fitted, and the flatness is reduced. Further, since the tip 2c of the flanged pin 2 protrudes from the date indicator holder 1, a relief of the tip 2c is provided in a component such as the date indicator guide plate provided thereunder, or the tip of the date indicator 2c is released. There was also a problem that parts such as boards had to be arranged.

うにする。Although not shown, a known date indicator guide plate is mounted on the base plate, and an annular plate-shaped date indicator 19 guided by the date indicator guide plate is rotatably provided on the outer periphery thereof. On the date indicator 19, a date indicator holder 20 as a plate member is placed and fixed, and the date indicator 19 is held down by the date indicator holder 20. The date wheel holder 20 has a day jumping system 20a, and the day jumping system 20a is engaged with the day star wheel 15. Further, on the date wheel holder 20, a day fast-forward lever (other member) 21 is provided in an overlapping manner together with the day turning intermediate wheel 14. The day fast-forward lever 21 includes a correction wheel engagement portion 21a and a day-feed engagement portion 21.
b, a forked portion 21c, and a spring portion 21d. The day feeding engagement portion 21b, the forked portion 21c, and the spring portion 21d are included.
And three flanged pins 2 on the date wheel holder 20 respectively.
Press with 2, 23, 24. The day fast-forward lever 21 is pressed against the flanged pin 23 by the spring portion 21d, and is guided by the flanged pins 22 and 23 against the spring portion 21d so that the day fast-forward lever 21 is slidable. When the winding stem 26 passing through the cylindrical correction wheel 25 is rotated in one direction, the correction wheel 25 is engaged with the correction wheel engaging portion 21a of the day fast-forward lever 21 and the day fast-forward lever 21 is moved to the spring portion. 2 so that the day feeding engagement portion 21b can be rotated on the day and engaged with the intermediate wheel 14, and the intermediate day wheel 14 can be advanced by one tooth. I do.

き上がりを防止してなる。The above-mentioned date indicator holder 20 is formed, as shown in detail in FIG. 1, by forming a cylindrical portion 20b projecting upward by, for example, burring. The flange 22a of the flanged pin 22, for example, is abutted against the top surface of the cylindrical portion 20b, and the flanged pin 22 is pressed into the through hole 20c of the cylindrical portion 20b. Thus, the flange 22a of the flanged pin 22 prevents the day fast-forward lever 21 from lifting.

Further, the other member for preventing the rising of the flange portion 22a of the flanged pin 22 from rising is the day fast-forward lever 21, but the present invention is not limited to this, and other levers and gears may be used. Further, the cylindrical portion 20b is formed on the flanged pin 22.
Alternatively, such a cylindrical portion may be formed.

置を制限する問題も解消することができる。According to the invention, therefore, a cylindrical portion is formed on a plate member such as a date wheel holder, and a flange portion of a flanged pin is abutted against the top surface of the cylindrical portion so that the inside of the cylindrical portion is formed. Since the flanged pin is press-fitted into the plate, the flanged pin has a simple shape that is easy to machine without a step as in the past, and the effect of the force applied when the flanged pin is press-fitted is hardly applied to the plate member. The deformation can be prevented. Further, since the press-fitting margin of the flanged pin becomes longer, the tip of the pin does not have to protrude from the plate member, thereby solving the problem of limiting the arrangement of other components provided below the plate member. .
