Description of the Related Art As a conventional technique of a band length adjusting structure for three-fold center clasp, there is one disclosed in Japanese Utility Model Application Laid-Open No. 4-107612 filed by the applicant of the present application. As shown in the perspective view of FIG. 6, this structure has a front cover 1 having one end connected to the intermediate plate 2, a slide in the front cover 1 and one end connected to the watch band 3, and A slide piece 4 having saw-toothed teeth formed so that the other end is bifurcated and facing each other inward, and two push buttons 6 provided with guide projections 5 that engage and disengage with the teeth of the slide piece 4. The push button 6 is configured to include a push button back cover 7 in which the push button 6 slides inside and a spring is provided which covers the back surface of the push button 6 and expands the two push buttons 6 outward. . The front cover 1 is composed of a front portion and both side portions, and has window holes 8 formed in the both side portions.
The push button 6 attached to the push button back cover 7 is provided, and the teeth of the slide piece 4 are engaged with the guide projections 5 of the push button 6. With this structure, when adjusting the length of the band,
This is done by pushing the slide piece 4 into the front cover 1 by the required length, and when returning to the original length, the slide piece 4 is pushed with the two push buttons 6 pressed (in the direction of the arrow).
Is pulled out from inside the front cover 1.

ズに挿入できず操作性に問題があった。However, in this structure, the push button 6 has the window hole 8 in the front cover 1.
Since it slides inside and inside the push button back cover 7, the outer circumference of the push button 6 is designed so as to allow clearance between the window hole 8 and the inside of the push button back cover 7. Further, since the slide piece 4 formed by the inner surface of the front cover 1 and the upper surface of the push button back cover 7 also slides, the outer periphery of the slide piece 4 and the slide piece insertion portion are It is designed to allow you to ski in between. Due to such a relationship between the design and the processing accuracy in manufacturing, when the slide piece 4 is inserted into the slide piece insertion portion, the slide piece 4 is loosened in the slide piece insertion portion. Therefore, when a force is applied in the direction in which the slide piece 4 comes out of the slide piece insertion portion, the push button 6
There is a problem that the guide projection 5 of the push button 6 is disengaged from the saw-toothed tooth of the slide piece 4 without performing the push operation. Further, when the slide piece 4 is inserted into the slide piece insertion portion, there is some play, so that the slide piece 4 cannot be smoothly inserted, and there is a problem in operability.

る。An object of the present invention is to solve the above-mentioned problems, to reduce the play between the slide piece insertion portion and the slide piece 4 extremely, and to ensure the engagement between the saw blade teeth and the guide projections. Another object of the present invention is to provide a structure for adjusting the length of a three-fold clasp, which allows the slide piece to slide smoothly in the slide piece insertion portion and improves operability.

される。Next, a method of adjusting the length of the watch band 21 will be described. The slide piece 23 inserted into the slide piece insertion portion formed by the inner surface of the front cover 20 and the slide piece pressing member 32 has the teeth 22 with which the guide projections 24 of the push buttons 25 and 26 are engaged. There is. In order to shorten the length of the watch band 21, the slide piece 23 can be pushed into the front cover 20 to have a predetermined length. At this time, the guide projection 24 formed on the push button 25 slides on the guide surface 32 of the tooth 22 formed on the slide piece 23, and when the pushing of the slide piece 23 is stopped when the predetermined length is reached, the guide is provided. The projection 24 engages with the stop surface 33 of the tooth 22, and the slide piece 23 is prevented from coming off the front cover 20. In addition, when the watch band 21 whose length has been adjusted to be short is to be lengthened again, the engagement between the stop surface 33 of the tooth 22 and the guide protrusion 24 can be released, and therefore both push buttons 2
Slide piece 23 while pressing buttons 29 of 5, 26
Is applied by applying a force in the direction of pulling out from the front cover 20.

The length of the watch band can be freely adjusted while wearing the watch on the slide, and it can be shortened easily and surely by pressing the slide piece, and even if the pulling force is accidentally applied to the slide piece, the guide protrusion The teeth are never disengaged. Further, when lengthening the watch band, it is possible to easily and surely lengthen it by applying force in the direction of pulling out the slide piece from the front cover while pressing the button portion of the push button. Moreover, since the structure is simple, the assemblability and the appearance quality are excellent.
