Next, the effect of the band installation constitution of such wrist-watch is described.
First, when watchband 10 is installed on Wristwatch case 1, assembles watch or clock glass 4, clock module 6 and back of the body lid 5 in the housing body 2 of Wristwatch case 1 in advance, at the outer peripheral face of housing body 2, bezel, cluster 3 is installed in this condition.
Now, at the outer peripheral face configuration bezel, cluster 3 of housing body 2, and by the outer peripheral face of bezel, cluster 3 covering shell main body 2, by multiple screw 3a, bezel, cluster 3 is fixed on the outer peripheral face of housing body 2 in this condition.Thus, the main body jut 9a of housing body 2 is covered by the bezel, cluster jut 9b of bezel, cluster 3, thus defines the band installation portion 8 possessing a pair installation jut 9 at Wristwatch case 1.
Under this state, first, at the end 10a of watchband 10, buffer unit 16 is installed.Now, the pipe portion 20a of spring rod 20 is made to be inserted in the connect apertures 22 of the end 10a of watchband 10, and the spring force overcoming volute spring (not shown) is pressed into pair of pin portion 20b in pipe portion 20a, and in this condition the linking part 18 of buffer unit 16 is configured at the upper surface of watchband 10, and make each arm 17 of buffer unit 16 corresponding with the two sides of the end 10a of watchband 10.
And, make the pin mounting hole 21 of each heavy section 17b being located at each arm 17 corresponding with the connect apertures 22 of the end 10a of watchband 10.Like this, the pair of pin portion 20b of spring rod 20 is extruded because of the spring force of volute spring (not shown), thus makes it the pin mounting hole 21 being inserted in each arm 17.Thus, clamp between the linking part 18 and spring rod 20 of buffer unit 16 and under the state maintaining watchband 10, buffer unit 16 be installed on the end 10a of watchband 10.
Afterwards, install between jut 9 for a pair that the end 10a of watchband 10 and buffer unit 16 is configured in together the band installation portion 8 being located at Wristwatch case 1.Now, each thinner wall section 17a of each arm 17 of buffer unit 16 is configured between the two sides of each main body jut 9a of a pair installation jut 9 and the end 10a of watchband 10, and makes the pin insertion hole 15 of each arm mounting hole 19 of each thinner wall section 17a, a pair installation each mounting hole 12 of jut 9 and the end 10a of watchband 10 corresponding on the same axis.
And, by connecting member 11, watchband 10 is installed on together with buffer unit 16 the band installation portion 8 of Wristwatch case 1.Now, make the first threaded portion 13 of connecting member 11 be inserted in the arm mounting hole 19 of an arm 17 of buffer unit 16 from the mounting hole 12 that a pair is installed each mounting hole 12 of jut 9, make the internal thread part 13a of the first threaded portion 13 after this insertion be inserted in the pin insertion hole 15 of watchband 10, the arm mounting hole 19 of another arm 17 of buffer unit 16 and another mounting hole 12 of installing in each mounting hole 12 of jut 9 for a pair.
Under this state, the external thread part 14a of the second threaded portion 14 of the connecting member 11 and internal thread part 13a of the first threaded portion 13 is made to be screwed and to tighten.Thus, between the two sides of the end 10a of watchband 10 and each main body jut 9a of band installation portion 8, flexibly push each thinner wall section 17a of each arm 17 of buffer unit 16, in this condition the end 10a of watchband 10 is installed on together with buffer unit 16 the band installation portion 8 of Wristwatch case 1.
