PROBLEM TO BE SOLVED: To provide a wrist-watch for which a band can be easily attached and detached to/from a body without using an exclusive tool, the sufficient attaching strength of the band to the body can be secured, scratches accompanying the attaching/detaching operation of the band can be suppressed as well and a using feeling is excellent. SOLUTION: Fitting feet 6 having attaching holes 7 are projectingly provided on a body 5, and a fitting crotch 5a for receiving the end piece 11 of the band 3 attachable and detachable to/from the body 5 so as to be taken in and out is formed between the fitting feet 6. A cam body 21 having a cam part 22 where an elliptic cam surface 22a is formed is housed in the end piece 11 so as to be rotated, and an operation groove 25 of the cam body 21 is exposed. A pair of attaching shafts 31 are housed in the end piece 11 across the cam part 22 so as to be moved in the width direction of the piece. Both attaching shafts 31 are provided with a cam driven surface 31a in contact with the cam surface 22a and are inserted and detached to/from the attaching holes 7 by the dimension difference of the long shaft and short shaft of the cam part 22 by the rotation of the cam body 21. An energizing body 35 is housed in the end piece 11 and the pair of attaching shafts 31 are respectively pressed to the cam surface 22a by the energizing body 35. COPYRIGHT: (C)2007,JPO&INPIT |
