In addition, the lid member 64 can be rotated and tightened or removed from the support member accommodating portion 61. As a result, the second engaging portion 63 and the compression coil spring S2 housed in the support member accommodating portion 61 can be easily replaced.

When connecting the main body 2, the band 3, and the bezel 4 to each other, first, the bezel 4 is attached to the bezel arrangement portion 25 of the main body 2 so as to cover it from the display portion 24 side. In the state where the band 3 is not attached, as shown in FIG. 4, the second engaging portion 63 is urged toward the recess 261 by the compression coil spring S2. Therefore, the support projection 632 of the second engaging portion 63 has moved to the inside of the support member accommodating portion 61. In a state where the flange portion 633 of the second engaging portion 63 is in contact with the inner wall in the support member accommodating portion 61, the support projection 632 is in a state of being moved to the opening portion 642 side. That is, in the state of FIG. 4, the second engaged portion 63 is located at the second non-engaged position where the second engaged portion 63 is not engaged with the second engaged portion 431 (the engaged state is disengaged). Therefore, the main body 2 and the bezel 4 can be easily attached and detached.

When connecting the band 3 to the main body 2, the operation portion 523 of the first engagement portion 52 provided in the band connection portion 31 of the band 3 is operated to cause the first engagement portion 52 to be connected to the compression coil spring S1. The band 3 is moved inward in the width direction against the elastic force, and the support portion 522 of the first engaging portion 52 is moved toward the opening 311 side as shown in FIG. When the two first engaging portions 52 are urged in the separating direction as in the clock 1 of the present embodiment, the two first engaging portions can be engaged by pinching the two operating portions 523 with fingers or the like. The portion 52 can be easily moved to the opening 311 side. Then, while the first engaging portion 52 is in the state of the first non-engaging position in which the first engaging portion 52 is moved to the opening 311 side, the band connecting portion 31 is placed on the back of the main body portion 2 with respect to the concave portion 261 of the main body portion 2. It is attached from the lid member 22 side (state in FIG. 4).

When the band connecting portion 31 is attached to the recess 261 the first engaging portion 52 and the second engaging portion 63 are located on substantially the same axis. When the operation of the operating portion 523 to the first engaging portion 52 is released, the first engaging portion 52 moves in the outward direction of the band connecting portion 31 due to the elastic force of the compression coil spring S1. Further, the compression coil spring S1 has a larger elastic force than the compression coil spring S2. Therefore, the first engaging portion 52 moves toward the first engaged portion 62 while pushing the second engaging portion 63 against the elastic force of the compression coil spring S2. In this case, the stepped portion between the guide portion 521 and the support portion 522 of the first engaging portion 52 abuts on the edge portion of the opening 512 formed at the end portion of the support member accommodating portion 51. (1) The movement of the first engaging portion 52 toward the engaged portion 62 side is restricted. The legs 26a of the main body connecting portion 26 are arranged on the outward direction side of the first engaging portion 52, respectively.

Further, the first engaging portion 52 can be easily positioned at the first non-engaging position by the operation of the operating portion 523 by the operator. Further, since the second engaging portions 63 and 66 can also be moved in conjunction with each other by operating the first engaging portion 52, a plurality of members (in the present embodiment, the first member, the second member and the second member) can be moved. It is possible to configure a coupling device capable of easily performing a coupling operation and a coupling disconnection operation between the three members).

Further, the first member, the second member and the third member of the coupling device include a device main body (main body portions 2, 2A, 2B in the present embodiment), bands 3, 3B to 3D, and an exterior member (bezel 4 in the present embodiment). , 4D) can be combined. Therefore, even in a device including a device main body, a band, and an exterior member, a connection operation and a connection release operation between a plurality of members can be easily performed.

Further, the first engaging portion 52 is urged to the first engaging position side by the first elastic member, and the second engaging portions 63 and 66 are second by a second elastic member different from the first elastic member. The coupling device urged to the second non-engaging position side with a force weaker than that of the one elastic member can also move the second engaging portions 63 and 66 by operating the first engaging portion 52. , The connection operation and the connection release operation can be performed with a simple operation.

Further, in the coupling device in which the first elastic member and the second elastic member are the compression coil springs S1 and S2, the first engaging portion 52 is moved to the first engaging position by the elastic force of the compression coil spring S1 and compressed. The elastic force of the coil spring S2 can move the second engaging portion 63 to the second non-engaging position. Further, since the first engaging portion 52, the second engaging portion 63, and the compression coil springs S1 and S2 can be arranged substantially coaxially, the circumference of the outer periphery of the first engaging portion 52 and the second engaging portion 63 can be arranged. The configuration of can be miniaturized.

Further, in the coupling device in which the first elastic member is the compression coil spring S1 and the second elastic member is the leaf spring S3, the first engaging portion 52 is moved to the first engaging position by the elastic force of the compression coil spring S1. The second engaging portion 66 can be moved to the second non-engaged position by the elastic force of the leaf spring S3. Further, since the leaf spring S3 can be arranged on a side different from the coaxial direction of the second engaging portion 63 and the compression coil spring S1, the axial configuration of the second engaging portion 66 can be miniaturized. can.

Further, the coupling device in which the leaf spring S3 is provided on the third member side of the second member can easily accommodate the leaf spring S3 in the second member by attaching and detaching the third member. Further, as shown in the second, fourth and sixth embodiments (see FIGS. 6, 10 and 13 and the like), the lid member 64 can be omitted, so that the second elastic member is accommodated. The configuration can be simplified.

Further, the first member has a first connecting portion in which the first engaging portion 52 is accommodated, and the second member is provided with the first engaged portion 62 and accommodates the second engaging portions 63 and 66. The third member has a second connecting portion, and the third member has a third connecting portion provided with the second engaged portions 431 and 31D1. A coupling device in which either two are hinged with the first engaging portion or the second engaging portion as the axis is described. Thereby, the coupling device can be applied to a device in which any two of the first member, the second member and the third member rotate according to the function.

Further, the first connecting portion has two first engaging portions 52 urged in the direction away from each other, and the second connecting portion is arranged on the outward direction side of the first engaging portion 52, respectively, and the third connection portion is connected. The configuration in which the portions are arranged on the outward direction side of the second engaging portion has been described. As a result, the operation portions 523 of the first engaging portions 52 can be collectively operated so as to be close to each other, so that it is possible to configure a coupling device in which the coupling operation and the coupling disconnection operation are easy.

Further, a coupling device having a covering portion 44 in which one of the first connecting portion, the second connecting portion and the third connecting portion covers the other two from the front side is a first connecting portion, a second connecting portion and a third. It is possible to reduce the exposure of the coupling structure of the coupling portion to the visible side, and to configure a safe and good-looking coupling device.

Further, in the coupling device shown in each embodiment, the first member, the second member, and the third member have two engaging portions (first engaging portion 52 and second engaging portions 63, 66). It was configured to engage with each of the two engaged portions (first engaged portion 62 and second engaged portion 431, 31D1). Temporarily, a single engaging portion (for example, the first engaging portion 52 in each embodiment) engages with two engaged portions (first engaged portion 62 and second engaged portion 431, 31D1). If it is configured to fit, the stroke (moving distance) of the engaging portion becomes long, and the engaging portion and the first member provided with the engaging portion become large. Further, in order to reduce the stroke, if the wall thickness in the stroke direction of the second member located between the first member and the third member is reduced, the strength of the second member is lowered and the design is restricted. Also occur. Further, when a single engaging portion is used, the stroke becomes long and the elastic force of the elastic member (compression coil spring S1 in the embodiment) that urges the engaging portion may be set to be large, and the operating portion may be set. It is also assumed that the operation by the 523 becomes difficult and the reaction force acting on each member (first member, second member and third member) that receives the elastic force increases.

In the coupling device shown in the present embodiment, since each stroke of the first engaging portion 52 and the second engaging portions 63 and 66 can be reduced, the above-mentioned is described as compared with the case where a single engaging portion is provided. Since the first member can be made smaller and the strength of each member can be made relatively low without such restrictions, the entire coupling device can be made smaller. Further, an existing spring rod can be used as the spring rod (the first engaging portion 52 in the present embodiment or the support member accommodating portion 51 including the engaging portion 52).
