伝達して時刻修正を行う構成であった。2. Description of the Related Art Conventionally, this type of portable timepiece has a structure as shown in FIGS. 5 and 6, for example. Reference numeral 1 in the figure is a base plate. On the front side of the main plate 1, a part 2a is fitted in the hole 1a, and a resin member 2 (for example, an insulating seat) made of a highly moldable material (for example, polyacetal) is attached. The resin member 2 has a winding stem groove 2b, and the tip 3a is put in the winding stem groove 2b to hold the winding stem 3 between the main plate 1. The resin member 2 includes
Further, a shaft portion 2c is provided at the upper portion in the figure, and a center hole 4a is fitted into the shaft portion 2c to rotatably attach the small iron wheel 4. Then, the wheel train bridge 5 is mounted on the resin member 2 by fitting the hole 5a to the tip 2d of the shaft portion 2c to prevent the small iron wheel 4 from coming off. The small iron wheel 4 meshes with the Hino back wheel 7 on the main plate 1 via an idler 6. As a result, when the winding stem 3 is pulled out to the time adjustment position, the crush wheel 8 is engaged with the small iron wheel 4, and when the winding stem 3 is subsequently rotated, the rotation is transmitted from the crush wheel 8 to the small iron wheel 4, and It was configured to transmit the time from the small car 4 to the Hino Ura 7 to adjust the time.

問題があった。The problem to be solved by the invention However, in such a conventional configuration, since the small iron wheel 4 is placed on the winding stem 3 while being supported by the resin member 2, there is a problem that there is a limit to thinning the timepiece movement. there were. Further, since the resin member 2 is used, there is a problem that the strength is weakened. Furthermore, since the height of the small iron wheel 4 and the height of the Hinoura wheel 7 do not match, the idler 6 is required, and there is a problem that the number of parts increases.
従来の携帯時計の中には、小鉄車を裏押えに取り付け
て地板の裏側に設けるものもあるが、この場合は裏押え
が要るし、地板の裏側でも組付け作業を行わなければな
らない問題があった。Some conventional mobile timepieces have a small iron wheel attached to the backing plate and are installed on the back side of the main plate, but in this case, the back pressing is necessary and the assembly work must be performed on the back side of the main plate. was there.
そこで、この考案の目的は、携帯時計において、その

ることが必要である。Further, in the above-described embodiment, the base plate, the plate member, and the train wheel bridge are made of a metal material, but they may be made of a resin material (for example, polycarbonate) having the same strength as metal. In this case, since those resin materials are hardly moldable, it is necessary to simplify the shapes of the main plate, the plate member and the train wheel bridge as much as possible.
考案の効果 したがって、この考案によれば、以下の効果がある。Effects of the Invention Therefore, according to this invention, there are the following effects.
小鉄車を巻真と地板との間に配置し、従来の樹脂部
材を不要とするから、時計ムーブメントを薄くし、その
薄型化を可能とする。Since the small iron wheel is arranged between the winding stem and the main plate and the conventional resin member is not required, the timepiece movement can be made thin and its thickness can be made thin.
地板・板部材・輪列受の３つの部材で小鉄車および
巻真を保持し、強度的に弱い樹脂部材を不要とするか
ら、強度を増して信頼性を向上することができる。Since the small iron wheel and the winding stem are held by the three members of the main plate, the plate member, and the train wheel bridge, and the resin member weak in strength is unnecessary, the strength can be increased and the reliability can be improved.
小鉄車を直接日ノ裏車に噛み合わせるから、アイド
ラを不要とし、また小鉄車を地板の表側に配置するか
ら、裏押えを不要とし、部品点数の削減を図ることがで
きる。Since the small iron wheel is directly meshed with the Hino back wheel, no idler is required, and because the small iron wheel is placed on the front side of the main plate, the back press is not required and the number of parts can be reduced.
地板表側のみの組付けで、裏側の組付け作業を不要
とすることができる。Assembling only the front side of the main plate makes it unnecessary to assemble the back side.
