特許第６６４６６３号として提案されている。2. Description of the Related Art Conventionally, a slit whose opening is narrower than the inner part is formed in a mounting can portion projecting from a side surface of a case, and a clasp body provided at a tip end portion of a band is outwardly extended by a coil spring. The pressed shaft part is slidably inserted, and an opening window is formed on the clasp body so as to face the shaft part.
A clasp for a watch band in which a large diameter portion and a small diameter portion are formed in a shaft portion and a push button is provided at the tip of the shaft portion is proposed as Swiss Patent No. 664663.

ことができる。In this clasp of a watch band, when the push button is pushed, the shaft part slides so that the small diameter part matches the opening window, and the shaft part can be attached and detached from the slit of the can part through the opening part. Then, when you release the push button, the coil spring pushes the shaft back to its original position, and the large diameter part matches the opening window, making it impossible to attach or detach it to the slit. You can easily replace the watch band without it.

の負担が大幅に増大する。However, in this structure, the clasp body must be formed with a passage through which the large diameter portion of the shaft can move, so that not only the clasp body becomes thick, but also the can portion has a large diameter portion. Since a slit that can be fitted is formed, the thickness becomes large and the appearance is bad. In addition, since the clasp body with a completely different structure from the other pieces must be attached to the tip of the watch band, the connection part between the watch band and the case feels uncomfortable, and the structure of the watch band becomes complicated and the cost increases. However, if a plurality of watch bands are prepared and they are appropriately replaced, the burden on the user is significantly increased.

外れる心配がある。Further, a locking hole and an insertion groove connected to the locking hole are provided on one mounting side, and a plate-shaped locking inclined in a certain direction with respect to the length direction of the band is provided on the other mounting side. Japanese Patent Laid-Open No. 1-99504 discloses a band connecting structure in which a portion is provided, the insertion groove is tilted and the locking portion is tilted for insertion, and the locking portion in the locking hole is rotated to prevent the band from coming off. Is proposed as. However, since the reverse rotation of the locking portion is prevented only by the tension applied to the watch band, the locking portion easily comes out of the locking hole, and there is a concern that the timepiece may come off during carrying.

落下する心配がない。Furthermore, if the slit is inclined so that its opening faces the case back direction of the case, even if the cam barrel rotates and the slit and the notch match when carrying the device, the tension applied to the band causes the protrusion of the protrusion. It is possible to prevent the timepiece from falling off by suppressing the escape from the slit. Also, if the push button is a hidden push button that does not protrude from the outer surface of the can portion when viewed from the surface, the push button does not appear on the outer surface when carrying the watch, and the appearance is good.
There is no fear that the push button will be pressed by an unintended external force while the watch is being carried and the band will suddenly come off the case and the watch will fall.
