1a is formed. At the other end, an engaging part 11b similar to the engaging part 6b of the locking metal fitting 3 extends upwardly, and protrusions 11c are formed at both ends of the engaging part 11b. Furthermore, a portion of both side edges of the metal fitting main body 11 in the band width direction is bent to form a protrusion 11d, which fits inside both side walls of the holding metal fitting 5. Further, holes 11e are provided in both of the protrusions 11d, respectively.

れる。 Next, to explain the operation of the clasp configured in this way, first, while holding down the locking metal 3 side of the watch band placed on your wrist so that it does not fall, use your fingers to press the front cover 13 of the clasp 5. When opened, front cover 1
3 rotates with respect to the latch 4 connected to the band piece 2, opens approximately 90 degrees upwards, and can be easily pinched. On the other hand, the hook 4 is fixedly positioned in a horizontal state together with the piece 2, and the hook 11a is hooked on the locking plate 7. At this time, the band curves along the curved surface of the arm, and force in the rotational direction acts on the locking plate 7 and the hook 11a, but due to the linear locking of both, the hook 11a firmly holds the locking plate 7 without rotating. to be locked. After being temporarily fastened in this manner, when the front cover 13 is pushed down with a finger, the snap member 14 elastically engages with the shaft 9 of the locking fitting 3, and the locking plate 7 and the hook 11a are engaged together with the front cover 13. It is maintained so that it does not come out of the stopped state.
