Problems solved by technology
[0004] However, in the conventional technology, the button has two functions of unlocking the buckle and adjusting the length, so there is a problem that it is difficult to distinguish between operations.
As a method for solving this problem, it is also considered to separately provide operation parts corresponding to the unlocking operation and the length adjustment operation of the buckle, but it is extremely difficult to realize such a structure without increasing the size of the mechanism.

Embodiment Construction
[0042] Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0043] FIG. 1 is an external perspective view showing the structure of a wristwatch 1 as an embodiment of a timepiece to which the present invention is applied.
[0044] The wristwatch 1 includes: a running mechanism (not shown in the figure), a dial 12, and a timepiece case 11 that accommodates hands 13 in a waterproof structure. The watch case 11 is connected to upper and lower ends (so-called main body) of the watch band 14 , which is a band-shaped accessory for fixing the watch 1 to the wearing part (wrist of the wearer). The strap portion 14 connects an upper strap 15 and a lower strap 16 , which are belt-shaped bodies connected to the timepiece case 11 , via a buckle 2 .
[0045] The upper band 15 is connected to the timepiece case 11 at the 12 o'clock position of the dial 12 , and the lower band 16 is connected to the timepiece case 11 at the 6 o'clock position of...

The present invention provides a clasp whose length can be adjusted by a simple and easy-to-understand operation, a belt-like accessory and a watch. The clasp is configured such that a moving unit 40 connected to an upper band 15 is fitted to a lid part 20 connected to a lower band 16. The lid part 20 is provided with a plurality of engaging holes 21C and 21D arranged in the longitudinal direction of a band part 14, the moving unit 40 is provided with a case 41 housed in the lid part 20, a projection member 44 projected from the case 41 and engaged with the engaging holes 21C and 21D and a button 42 exposed on the surface of the case 41, and the projection member 44 is pulled into the side of the case 41 by the operation of the button 42.
Description
technical field [0001] The present invention relates to a buckle, a belt accessory having the buckle, and a timepiece. Background technique [0002] Various buckles are used in strap accessories such as watch bands. For example, a wristwatch uses a folding buckle such as a two-fold buckle, a three-fold buckle, or a butterfly (half-fold) buckle. In such a folding buckle, a structure in which a moving member connected to a wristband is movably supported on the buckle cover, and a button for locking / unlocking the buckle is locked in the moving member has been proposed. There is a proposal to perform unlocking of the buckle and fine adjustment of the length of the strap by operating this button (for example, Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2005-270248 [0004] However, in the conventional technology, since the button has two functions of unlocking the buckle and length adjustment, there is a problem that it is difficult to disting...
