A date plate retainer 32 and a date plate retaining screw 34 for positioning a calendar display member such as 35 so as to be freely rotatable are provided. The date plate holding screw 34 is provided on the upper surface side of the date plate holder 32, and is attached to a screw portion 33a formed on the date plate holding fixed shaft 33 through a hole 32a formed in the date plate holder 32. The date plate retainer 32 is fastened and fixed.

の２種類の部品が必要であり、さらに、これらの部品は
日板押え32を固定するために通常３ヵ所配設されるので
合計６部品必要になる。According to the conventional example, the date plate holding fixed shaft 33 is pressed and fixed in the hole 31a made of plastic resin, and the fixing force is sufficiently larger than the pressing force when the date plate holding screw 34 is tightened (pulling force). 1kg or more). Therefore, the hole between the date plate holding fixed shaft 33 and the clock base 31
Hamagotake l 4 is 500μm approximately at a minimum of 31a (fitting diameter is φ10
(At the time of 00 μm), and the thickness m 4 of the clock base 31 becomes a considerably large value (about 1000 μm). In order to fix the date plate holder 32, two kinds of parts, a date plate fixing shaft 33 and a date plate fixing screw 34, are necessary. Further, these parts are usually used for fixing the date plate holder 32. A total of six parts will be required because three parts will be installed.
以上のことから従来の日板押え固定構造では、日板押
えの固定部がかなり厚くなるので、薄型のカレンダー付

いる。In view of the above, in the conventional fixing structure of the date plate holder, the fixing portion of the date plate pressing becomes considerably thick, so that it is extremely difficult to develop the watch with a thin calender. Further, six parts are required for fixing the date plate pressing. There is a drawback such as an increase in the cost of the watch because it becomes necessary, which lowers the competitiveness of the watch.
本考案の目的は、上記のような従来の日板押えの固定
構造の問題点を解消させ、時計の薄型化、低コスト化に
適する日板押えの固定構造を提供することである。SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the conventional fixing structure of a date holding member, and to provide a fixing structure of a date holding member suitable for thinning and reducing the cost of a timepiece.
上記目的を達成するために、本考案は次のような構成
となっている。In order to achieve the above object, the present invention has the following configuration.
すなわち、中空構造のボス部が形成されたプラスチッ

特徴とするものである。That is, a clock base made of a plastic resin having a hollow boss formed thereon, and a date plate holder mounted on the clock base for rotatably positioning and fixing a calendar display member such as a date wheel. In the above structure, the boss portion is formed in a sunken portion provided on a date plate holding surface, and a burring hole formed in the date plate is fitted around an outer periphery of the boss portion. Are positioned and fixed.
以下に本考案の実施例を図面に基づいて説明する。第
１図は本考案の実施例を示す日板押え固定構造の断面図
である。An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of a fixing mechanism for fixing a date plate showing an embodiment of the present invention.
第１図において、１はプラスチック樹脂製の時計基台

ー表示部材（図示せず）を回転自由に位置決め固定する
ための金属製の日板押えで、日板押え２には絞り加工
（バーリング加工）で形成された高さh1の丸型突起部2b
があり、丸型突起部2bの中心にはバーリング穴部である
穴部2aが形成されている。そして時計基台１のボス部1a
の外周に、日板押え２の穴部2aを嵌合させて日板押え２
を固定している。In FIG. 1, reference numeral 1 denotes a clock base made of a plastic resin, and a sunken part 1b is provided in a receiving surface of the clock base 1 which receives a date plate holder.
Are formed, and a boss portion 1a having a hollow structure is formed in the sunken portion 1b. Reference numeral 2 denotes a metal date plate retainer for rotatably positioning and fixing a calendar display member (not shown) such as a date wheel on which a date is printed. The date plate press 2 is formed by drawing (burring). formed of a height h 1 round protrusion 2b
A hole 2a which is a burring hole is formed at the center of the round projection 2b. And the boss 1a of the clock base 1
The hole 2a of the date plate retainer 2 is fitted to the outer periphery of
Is fixed.
この時、日板押え２の固定は、時計の通常携帯での衝
撃や振動で外れないことが前提であり、そのためには時
計基台１のボス部1aと、日板押え２の穴部2aとの嵌合丈
l1は最小でも500μｍ程度にする必要がある。そのた
め、日板押え２の穴部2aの高さh1は日板押え２の板厚
（通常200μｍ程度）よりかなり大きな値（500μｍ以
上）にしなければならないので、先に述べた絞り加工に
より丸型突起部2bを形成している。At this time, it is assumed that the fixing of the date plate holder 2 does not come off due to the impact or vibration of the watch when the watch is normally carried. Mating length with
l 1 needs to be at least about 500 μm. Therefore, the height h 1 of the hole 2a of the date plate retainer 2 must be considerably larger (500 μm or more) than the plate thickness of the date plate retainer 2 (usually about 200 μm). The mold projection 2b is formed.
また、時計は定期点検や部品交換で何回か分解、組立

押え２の嵌合によりボス部1aから削りかすが生じたとし
ても、それは沈み部1bの中に封じ込められて飛散しない
から、時計機能に悪影響を及ぼすこともない。In addition, the timepiece must be disassembled and assembled several times for periodic inspection and replacement of parts, so that the fixing force of the date plate holder 2 must be stable during the disassembly and assembly. Therefore,
Make the center of the boss 1a of the watch base 1 a hole (hollow structure)
The amount of shaving of the outer periphery of the plastic resin boss 1a when the hole 2a of the date plate retainer 2 is pushed in is minimized so that the hole 2a of the date plate retainer 2 is fitted smoothly. As a result, the fixing force of the date plate retainer 2 is stable without largely changing even if the watch is disassembled and assembled many times. Even if shavings are generated from the boss portion 1a by the fitting of the date plate holder 2, the shavings are sealed in the sinking portion 1b and do not scatter, so that the clock function is not adversely affected.
また、時計基台１の厚さm1は中空構造のボス部1aの丈
と、沈み部1bの下面側の厚さ（200μｍ以上）で決ま
り、最小厚さとしてはおよそ700μｍ程度に設定でき
る。The thickness m1 of the timepiece base 1 is determined by the length of the boss portion 1a of the hollow structure and the thickness (200 μm or more) of the lower surface side of the sunken portion 1b, and the minimum thickness can be set to about 700 μm.

で、薄型のカレンダー付き時計の実現が可能になる。As is apparent from the above description, according to the embodiment of the present invention, the hole formed in the date plate retainer is fitted to the outer periphery of the hollow boss portion formed in the plastic resin timepiece base and the date is fixed. Since the plate retainer is fixed, the date plate retaining shaft and the date plate retaining screw which have been conventionally used for fixing the date plate retainer are not required. Therefore, the number of parts is reduced, and the cost of the timepiece can be reduced. Furthermore, since clock base thickness m 1 can also be considerably thinner than a conventional timepiece base thickness m 4, it is possible to realize a thin calendar watch of.
