窓13より表出している。Ratchet holes 2a, 2b are provided in parallel on both side walls 1a, 1b of the upper box 1.
3a and 3b are guide plates, and 4a and 4b are bending stoppers. Further, 5 is a concave portion into which a rotary cover for double lock, which will be described later, is fitted at the time of locking, and 6 is a finger hanging concave portion. An auxiliary box 7 is fitted in the upper box 1. The ratchet pieces 9a and 9b are enclosed by the application spot lid 10 with the coil spring 8 sandwiched on the inner surface of the front portion of the auxiliary box 7. Reference numerals 11a and 11b are ratchet pawls, which are hooked on and released from the ratchet holes 2a and 2b. 12a and 12b are knobs for compressing the coil spring 8 and retracting the ratchet pawl,
It is exposed from window 13.
なおラチェット爪は掛脱を容易にするため傾斜12cを附
している。The ratchet pawl is provided with a slope 12c to make it easier to hang.

助箱７をスライド出しして調整するのである。One half of the band 14 is connected to the auxiliary box 7, and the other half of the band 17 is connected with the intermediate piece 15 and the lower piece 16 connected to the upper box 1 interposed. A rotating cover 19 for double lock is attached using a connecting shaft 18 of the lower piece 16 and the band 17. 20 is a window hole provided in the middle piece 15 and the lower piece 16. A watch (not shown) is attached between the bands 14 and 17 to form a wristwatch,
Although it is worn around the wrist according to the usual method, when the wheel as a wristwatch is small, the knobs 12a and 12b are clamped and the auxiliary box 7 is slid out for adjustment.

するのが防止される。Slide adjustment can be performed until the spot lid 10 contacts the stoppers 4a and 4b. That is, when the knobs 12a and 12b are held between the coil springs 8 and the ratchet pawls are retracted from the ratchet holes, the coil springs 8 can be slid very lightly. When sliding the auxiliary box 7 in the direction of the arrow, the auxiliary box 7 may be pushed with fingers. It moves to the upper box 1 side while making a clicking sound due to the characteristics of the ratchet, and the auxiliary box 7
You can adjust the width of the. Further, when it is mounted around the wrist, the rotary cover 19 is fitted into the recess 5 of the upper box 1 and double locked. Thus, the auxiliary box 7 is prevented from sliding unexpectedly.

ずる。<Effect of the Invention> Since the present invention fits the auxiliary box to the upper box by using the ratchet mechanism as described above, it is possible to adjust the length of the upper box by manually inserting and removing the auxiliary box. The effect that it can be produced.
ラチェット機構を構成するコイルばね、ラチェット片を
スポット蓋にて被覆したので、反複使用しても故障を生
じないという効果を生ずる。Since the coil spring and the ratchet piece constituting the ratchet mechanism are covered with the spot lid, there is an effect that a failure does not occur even when used repeatedly.
回動カバーによりダブルロックするので、装着した際に
みだりに上箱が展開しないという効果を生ずる。Since it is double-locked by the rotating cover, there is an effect that the upper box does not unintentionally deploy when mounted.
