And then, be entrenched in position among the connecting hole 21C of cap 20, shoulder 44B and gathering sill end face 24E butt at the leading section 44A of protruding member 44.In addition, be entrenched in position among the connecting hole 21D, shoulder 44B and gathering sill end face 24F butt at leading section 44A.Therefore, the wearer is as long as be that benchmark moves mobile unit 40 with gathering sill end face 24E, 24F.That is,, just leading section 44A can be inserted among connecting hole 21C, the 21D smoothly while when pushing button 42 mobile unit 40 is moved, remove in position to the pushing of button 42 with feel that shoulder 44B touches gathering sill end face 24E, 24F.Therefore, contraposition is carried out in position that needn't visual leading section 44A etc., so can easily regulate the length of watchband portion 14.

In addition, in the above-described embodiment, be the structure that on cap 20, is formed with connecting

hole

21C, 21D side by side, but the present invention is not limited to this, also can form more connecting hole side by side.At this moment, as long as gathering sill end face 24E, the 24F of gathering sill 24B are arranged in such position: when leading section 44A is entrenched in the connecting hole that is positioned on the limit, the position of shoulder 44B institute butt.

In addition, though be that mobile unit 40 is contained between the

sidewall

26,27, when pressing operation button 42, the structure that in gathering sill 24B, moves from the shoulder 44B and the leading section 44A of the outstanding protruding member 44 of housing 41, but the present invention is not limited to this, the two ends that for example also can be housing 41 arrive gathering sill 24B, and leading section 44A draws in the structure in the housing 41 fully.For this example, describe with reference to Figure 16～Figure 18.

Figure 16～Figure 18 is the partly cut-away vertical view of expression as the major part structure of the cap 20 of variation.

In this variation, as shown in figure 16, shell end 41D enters among the gathering sill 24B, and leading section 44A gives prominence to and is entrenched in the connecting hole 21C from this shell end 41D.Here, when button 42 was carried out pressing operation, as shown in Figure 17, leading section 44A was contained in the housing 41 fully.Under this state, shell end 41D is contained in the gathering sill 24B, so can in the scope that shell end 41D moves along gathering sill 24B mobile unit 40 be moved.Therefore, for example as shown in figure 18, can make upwards watchband 15 side shiftings of mobile unit 40, pushing of disengage button 42 is entrenched in protruding member 44 among the connecting hole 21D.

In addition, as shown in figure 17, be entrenched in position among the connecting hole 21C of cap 20, shell end 41D and gathering sill end face 24E butt at the leading section 44A of protruding member 44.In addition, be entrenched in position among the connecting hole 21D, shell end 41D and gathering sill end face 24F butt at leading section 44A.Therefore, the wearer is as long as be that benchmark moves mobile unit 40 with gathering sill end face 24E, 24F.That is,, just leading section 44A can be inserted among connecting hole 21C, the 21D smoothly while when pushing button 42 mobile unit 40 is moved, remove in position to the pushing of button 42 with feel that shell end 41D touches gathering sill end face 24E, 24F.Therefore, contraposition is carried out in position that needn't visual leading section 44A etc., so can easily regulate the length of watchband portion 14.

Like this, in the example of Figure 16～shown in Figure 180, shell end 41D is entrenched among the gathering sill 24B, protruding member 44 fully is contained under the situation of the structure in the housing 41 by the operation of button 42 even be made as, and also can obtain the effect same with above-mentioned embodiment.

In addition, in the above-described embodiment, the button 31 of pushbutton unit 30 is made as writing board shape, corresponding, the button inserting hole 24A of ways 24 is made as slotted hole, thus that ways 24 is fixing obliquely with respect to cap 20.The present invention is not limited to this, for example as shown in figure 19, also can on the face that cap 20 and ways 24 join boss 24D be set on ways 24, is provided with on cap 20 and the corresponding recess of this boss 24D (diagram slightly).At this moment, cap 20 is fixed to mutually not tilt by button 31 and boss 24D with ways 24.

In addition, detailed structure for illustrated in the above-described embodiment wrist-watch 1 is arbitrarily, for example as the order of shaping housing 41, as shown in figure 20, can accordingly the central portion of flat board be configured as narrower width with linking part 46, and be that the border folds with this central portion, housing 41 thus is shaped.At this moment, as long as when finishing, form as the groove of 41A of lateral opening portion and hollow bulb and be provided with in this groove that peristome constitutes button embedded hole 41B, button withdraws from the 41C of portion.In addition, also can when folding, become and on the part on border circular groove is set and is made as inserting hole 46A.This is an example only, also can form housing 41 by other method, and the manufacturing process of other part etc. also is arbitrarily.
