Abrégé

Disclosed is an assembly structure for a slide structure, in which both a casing and sliders to be slidably fitted in the casing can be made of a ceramic material. In the slide structure, the paired sliders (2 and 3) are shrunken inward in the through hole (14) of the casing (1). The paired sliders (2 and 3) have slide grooves (25 and 35) individually formed in the shrinking direction. The casing (1) has a through hole (13) for accommodating the paired sliders (2 and 3), and a mounting window (16) opened in the side face of the casing (1) and communicating with the through hole (13). A stopper (5) is fitted from the mounting window (16) in the individual slide grooves (25 and 35) of the sliders (2 and 3), and is supported on the inner walls of the casing (1), so that the paired sliders (2 and 3) have their slide ranges regulated by the slide grooves (25 and 35) and the stopper (5).

Provided is a band of piece-connected structure, which has pieces formed of ceramics or a super-hard alloy, which is excellent in appearance, which can be easily worked, and which is reliably assembled. The band of piece-connected structure is made by staggering pluralities of outer pieces (2) and inner pieces (1) and by connecting the adjoining outer pieces (2) and inner pieces (1) individually through connecting pins (3). The outer piece (2) is constituted to include a bottomed inner cap member (5) containing two tubular members (4) having a C-shaped section, a retaining member (6) covering the open side of the inner cap member (5), having two through holes (6a) corresponding to the tubular members (4), and retained in the portion of the inner cap member (5), and an outer cap member (7) housing and fixing the unit body having the retaining member (6) retained on the inner cap member (5). The outer pieces (2) are individually arranged on the two sides of the inner pieces (1) such that the connecting pins (3) are loosely fitted in through holes (1a) of the inner pieces (1), and such that the two end portions of the connecting pins (3) are individually fitted on the tubular members (4) through through holes (5b) in the inner cap member (5) of the outer pieces (2).

Intended is to provide an intermediate clasp for a band, which has an excellent wearing feel on a wrist or the like but does not hurt, when worn, the wrist or finger and the clothes. The intermediate clasp includes a curved base plate (1), two curved folding plates (2) connected directly or indirectly to chain members (C) and supported turnably on the two end portions of the base plate (1) so that they can be folded and extended in a hinged double door manner, and a lock mechanism (4) for locking the folded closure of the folding plates. The lock mechanism (4) adopts a constitution, in which it is locked not through the base plate (1) butdirectly between the folding plates (2).
