であつた。Technical background of the invention An example of a time setting mechanism for a watch that rotates the hands without a slip mechanism is, for example, the Utility Model 58-
99682. According to this publication, the intermediate wheel is moved in the axial direction by external operation, and this movement disconnects the second hand wheel and the minute hand wheel.
しかしこの中間車に対する分針車の噛合関係
は、中間車が軸方向に移動しても常に噛合関係を
保つ必要があるため、この中間カナの歯幅が不必
要に長くなるという問題があつた。 However, the meshing relationship between the minute hand wheel and the intermediate wheel must always be maintained even when the intermediate wheel moves in the axial direction, so there has been a problem that the tooth width of the intermediate pinion becomes unnecessarily long.

を図ることである。Purpose of the invention The purpose of the invention is to coaxially separate the shaft of the intermediate gear that meshes with the seconds pinion and the shaft of the intermediate pinion that meshes with the minute gear, so that the intermediate pinion rotates in a fixed position without being able to move in the axial direction. The shaft of the intermediate gear is movable in the axial direction relative to the shaft of the intermediate pinion, but is fitted so that rotation is transmitted. The goal was to shorten the tooth width of the long intermediate pinion to the minimum necessary to make the mechanical body of the watch thinner.

正される。Structure and key points of the invention In order to transmit the rotation of the seconds pinion to the minute gear, the intermediate wheel and the intermediate pinion have a two-shaft separation structure on the same axis.
Further, the two shafts are fitted and connected to a structure that allows relative movement in the axial direction but transmits rotation, and the shaft of the intermediate gear is provided to be movable with a sufficient stroke for the intermediate gear to disengage from the second pinion. It is being
When rotating the hands, pull up the shaft of the intermediate gear to disengage the intermediate gear from the seconds pinion.
In this state, the hour and minute hands are adjusted by turning the shaft of the intermediate gear.

起２７が形成されている。Embodiment In FIG. 1, the following wheel train is supported by an upper plate 1, a middle plate 2, and a lower plate 3. That is, a second hand shaft 6 is press-fitted into a second pinion 4 and a second gear 5, which are integrally formed with each other. It passes through the tube body part 8 of. The second hand shaft 6 is urged toward the bearing 7 by the spring force of the leaf spring 9.
A minute pipe 11 integral with a minute gear 10 is rotatably fitted into the outer periphery of the tubular body portion 8, and an hour pipe 13 integral with an hour gear 12 is further fitted onto the outer periphery thereof. A minute pinion 14 integral with the minute gear 10 meshes with a date pinion 15, and a date pinion 16 meshes with the hour gear 12. The back gear of the day 15 (the back kana of the day 1)
6) is rotatably supported by a shaft portion 17 integral with the intermediate plate 2. An intermediate pinion 19 is rotatably supported by a grooved shaft 18 integrally projecting above the shaft 17 and meshes with the minute gear 10. In this embodiment, the axial movement of the intermediate pinion 19 is restricted by the protrusion 20 at the tip of the shaft portion 17. An intermediate gear 21 meshes with the second pinion 4, and its shaft 22 and a shaft 23 of the intermediate pinion 19 are coaxial and interlocked in the following structure. The shaft 23 of the intermediate pinion 19 has a non-circular hole 24 as shown in FIG. 2, and the lower part of the shaft 22 of the intermediate gear 21 fits into the hole 24 with a cross-sectional shape that matches. That is, the shaft 22 is slidable in the axial direction with respect to the shaft 23, but rotation is transmitted to each other. The upper part of the shaft 22 is located in the hole 25 of the upper plate 1.
A needle turning knob 26 is fixed to the projecting end thereof. The shaft 22 is movable in the axial direction with a stroke sufficient for the intermediate gear 21 to disengage from the second pinion 4 as shown by the chain line.
A small protrusion 27 is formed on the outer periphery of 2 to provide a click motion.

The intermediate gear 21 is meshed with. The minute gear 5 is connected to the minute gear 5 via a clock motor and a drive wheel (both not shown).
By driving, the hand movement operation is performed in exactly the same manner as in the conventional case. To adjust the time, pull up the knob 26 to the position indicated by the chain line in FIG. As a result, the intermediate gear 21 is disengaged from the second pinion 4 as shown by the chain line. When the knob 26 is turned in this state, the rotation is transmitted from the shaft 22 to the shaft 23, and the wheel train after the minute gear 10 is driven via the intermediate pinion 19, thereby correcting the time.
