【考案の詳細な説明】
（産業上の利用分野）
本考案はステツプ運針における秒針に関するも
のである。[Detailed description of the invention] (Field of industrial application) The present invention relates to a second hand in step movement.
（従来の技術）
従来から秒針軸に秒針を取付ける構造は、軸先
端へ秒針のパイプを圧入することにより取付けて
いた。(Prior Art) Conventionally, the structure for attaching the second hand to the second hand shaft has been by press-fitting the second hand pipe into the tip of the shaft.
（考案が解決しようとする問題点）
しかし圧入による構成は、ステツプ秒針時計に
おいて、秒針が文字板目盛上に正確に位置調整す
ることが困難であり、そのため秒針と目盛とは位
置ずれしているものがあつた。(Problem that the invention aims to solve) However, with the press-fit configuration, it is difficult to accurately position the second hand on the dial scale in step second hand watches, and as a result, the second hand and scale are misaligned. Something was warm.
そこで本考案の目的は、簡単な構成により秒針
が文字板の目盛上を正確に運針できるようにした
ステツプ運針における秒針を提供することにあ
る。 SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a second hand with a simple structure that allows the second hand to move accurately on the scale of the dial.
（問題点を解決するための手段）
そして本考案の特徴は、秒針軸を秒針の取付部
に中心角６度のピツチのセレーシヨン嵌合により
圧入したところにある。(Means for Solving the Problems) A feature of the present invention is that the second hand shaft is press-fitted into the second hand mounting portion by serration fitting with a center angle of 6 degrees.
実施例
以下本考案の実施例を図面を参照して説明す
る。Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings.
第１図において、時計機械体により駆動回転さ

ずつの溝は、文字板の分目盛とそれぞれ対応して
いる。またセレーシヨン２と秒針歯車（図示せ
ず）とは、予め位置合せしてある。 In FIG. 1, a male serration 2 having a sawtooth cross section (FIG. 3) is carved all around the outer periphery of the tip of a second hand shaft 1 which is driven and rotated by a timepiece mechanism. Serration 2 has a central angle of 6 around the entire circumference.
It is divided into 60 equal parts by a groove. and serration 2
Since the pitch is engraved at 6 degrees, each groove corresponds to the minute scale on the dial. Further, the serration 2 and the second hand gear (not shown) are aligned in advance.
秒針軸１に取付ける秒針３には、第２図示のよ

ーシヨン２と相互に嵌合する雌側セレーシヨン５
が刻設してある。 The second hand 3 attached to the second hand shaft 1 is integrally formed with a pipe part 4 which serves as a mounting part as shown in the second figure. Female side serration 5 to be mated
is engraved.
そこで秒針軸１への秒針３の取付けは、軸先端
の雄側セレーシヨン２へ秒針パイプ部４の雌側セ
レーシヨン５を圧入して嵌合すればよい。 Therefore, the second hand 3 can be attached to the second hand shaft 1 by press-fitting the female serration 5 of the second hand pipe portion 4 into the male serration 2 at the tip of the shaft.

は、この軸の全周に設ける必要はなく、少なくと
も軸先端部の外周の一部に設けてあればよい。 Note that even if the tip of the second hand shaft 1 is shaped like a pipe, a male serration is provided on the inner wall of the pipe, and the male serration provided on the outer periphery of the mounting shaft protruding from the second hand 3 is fitted into the female serration. good. Also, the male side serration 2 of the second hand shaft 1
It is not necessary to provide the entire circumference of this shaft, but it is sufficient that it is provided at least on a part of the outer circumference of the tip of the shaft.
（考案の効果）
本考案は、秒針軸への秒針の取付け作業が簡単
かつ容易であり、さらに秒針が文字板の目盛上を
正確に運針することができる効果を有するもので
ある。(Effects of the Invention) The present invention has the effect that attachment of the second hand to the second hand shaft is simple and easy, and furthermore, the second hand can be moved accurately on the scale of the dial.
