  An operation window (window) 20 </ b> A is opened on the upper surface of the flat plate portion 21. The operation window 20 </ b> A is a substantially rectangular hole that penetrates to the back surface of the flat plate portion 21, and the circumferential surface is tapered so that the opening area on the back surface side becomes small. The lower end of the peripheral surface of the operation window 20A protrudes below the back surface of the flat plate portion 21, and constitutes an edge 20B as an engaging portion. And as shown in FIG. 3, the slide part 40 is exposed from the operation window 20A.

FIG. 6 is a perspective view showing the configuration of the slide portion 40. The slide part 40 as the moving member is located on the middle plate 25 side when disposed on the lid part 20 and receives a pressing operation described later, a connecting part 43 connected to the upper band 15, It is comprised from the standing wall part 42 which connects the press part 41 and the connection part 43. FIG.
The pressing portion 41 is provided with a rising portion 41A, a flat plate portion 41B, a first convex portion 41C, a second convex portion 41D, and a flat plate portion 41E in order from the tip by bending a single rectangular flat plate. It is. The rising portion 41A is a portion where the tip of the slide portion 40 is bent upward. The first convex portion 41 </ b> C as the protruding portion is a convex portion having a substantially trapezoidal cross-sectional shape including two upward inclined surfaces and a top flat surface connecting these inclined surfaces, and extending in the width direction of the lid portion 20. The 2nd convex part 41D as a protrusion part is a convex part extended in the width direction of the cover part 20 along with the flat plate part 41E side of the 1st convex part 41C. Similar to the first convex portion 41C, the second convex portion 41D has a substantially trapezoidal cross-sectional shape including two upward inclined surfaces and a top plane connecting these inclined surfaces. The inclined surface on the flat plate portion 41E side constituting the first convex portion 41C and the second convex portion 41D is configured to have a higher elevation angle than the other inclined surface. In addition, the height of the first protrusion 41C and the width of the top plane are larger than those of the second protrusion 41D.
The base end portion of the flat plate portion 41 </ b> E is connected to one end of the standing wall portion 42 that bends substantially vertically, and the other end of the standing wall portion 42 is connected to the lower plate portion 43 </ b> A of the connecting portion 43. The lower plate portion 43A is a flat plate formed one step lower than the flat plate portion 41E, and side walls 43B and 43C are provided on both side ends of the lower plate portion 43A. Each of the side walls 43B and 43C is formed with a long hole 40A extending along the longitudinal direction of the slide portion 40 and a spring bar insertion hole 40B through which a spring bar 37 described later is inserted.

As shown in FIG. 5, the slide portion 40 is disposed so as to overlap the lid portion 20. The pressing portion 41 of the slide portion 40 is located below the operation window 20A, and the first convex portion 41C and the second convex portion 41D are exposed from the operation window 20A. Since the widths of the first convex portion 41C and the second convex portion 41D are configured to be smaller than the opening width of the operation window 20A, the whole including the both side ends of the first convex portion 41C and the second convex portion 41D is operated. It is exposed from the window 20A. The rising portion 41 </ b> A is located closer to the middle plate 25 than the operation window 20 </ b> A and is hidden behind the flat plate portion 21. The flat plate portion 41 </ b> E is located between the flat plate portion 21 and the button unit 30. A support protrusion 49 provided on the upper surface of the button unit 30, that is, on the flat plate portion 21 side is in contact with the flat plate portion 41E. The support protrusions 49 are obtained by fixing a rounded protrusion to the main body of the button unit 30 and support the flat plate portion 41E from below. The support protrusion 49 may be a single elongated protrusion extending in the width direction of the flat plate portion 21, or may be constituted by a plurality of protrusions arranged in the width direction of the flat plate portion 21.
The standing wall portion 42 is located on the upper band 15 side of the button unit 30 and parallel to the side surface of the button unit 30 main body. Further, the lower plate portion 43 </ b> A connected to the lower end of the standing wall portion 42 extends to the upper band 15 side substantially in parallel with the flat plate portion 21. A spring rod 37 straddling the side walls 22 and 23 is inserted through the long holes 40A of the side walls 43B and 43C. A spring bar 39 is attached to the spring bar insertion hole 40B, and the side bars 43B and 43C and the top piece of the upper band 15 are connected by the spring bar 39.

A method for adjusting the length of the band portion 14 by operating the middle terminal 2 configured as described above will be described.
As shown in FIGS. 5 and 7, the slide portion 40 is connected to the lid portion 20 by a spring bar 37 inserted through the long hole 40 </ b> A. Since the long hole 40A is a long hole extending in the longitudinal direction of the band portion 14, the spring bar 37 is movable in the long hole 40A, and the relative position between the lid portion 20 and the slide portion 40 in the movement range. Can be shifted.
When a force in the direction of extending the band portion 14 is applied in the state shown in FIG. 5, the edge 20 </ b> B of the operation window 20 </ b> A engages with the second convex portion 41 </ b> D, and the lid portion 20 and the slide portion 40 are relative to each other at this position. Movement is restricted. Moreover, when the force of the direction which shrinks the band part 14 is added, since the standing wall part 42 hits the side surface of the button unit 30 main body, the band part 14 is hardly shortened.
For this reason, the length of the band portion 14 is substantially fixed when the second convex portion 41D contacts the edge 20B.

When the first convex portion 41C exposed to the operation window 20A is pressed in the state of FIG. 5, the pressing portion 41 is elastically deformed with the support protrusion 49 as a fulcrum by this pressing force. By this deformation, the second convex portion 41D is displaced below the lower end of the edge 20B, and the second convex portion 41D is detached from the edge 20B. That is, the pressing part 41 acts as an urging part, and urges the first convex part 41C and the second convex part 41D to the lid part 20 side.
When the first convex portion 41C is pushed into the upper band 15 side while the first convex portion 41C is pressed, the second convex portion 41D sinks into the back side of the flat plate portion 21, and the edge 20B is connected to the first convex portion 41C. It is located between the second convex portion 41D.
Here, when the force that presses the first convex portion 41C is released, the pressing portion 41 is restored by its own elastic force and displaced upward, and as shown in FIG. 7, the first convex portion 41C and the second convex portion are displaced. The edge 20B engages with the portion 41D.

When a force is applied to extend the band portion 14 in the state shown in FIG. 7, the edge 20B of the operation window 20A and the first convex portion 41C are engaged, and at this position, the lid 20 and the slide portion 40 are relative to each other. Movement is restricted. In addition, when a force in a direction in which the band portion 14 is contracted is applied, the second convex portion 41D hits the edge 20B, and thus the band portion 14 is hardly shortened.
For this reason, the length of the band portion 14 is substantially fixed when the first convex portion 41C contacts the edge 20B.
When the state shown in FIG. 5 is compared with the state shown in FIG. 7, the relative position of the lid portion 20 and the slide portion 40 is different, so that the length of the middle terminal 2 changes. That is, the length of the band portion 14 is changed by relatively moving the lid portion 20 and the slide portion 40.

Thus, in the middle end 2 of the first embodiment, the first convex portion 41C exposed to the operation window 20A is moved in the longitudinal direction of the band portion 14 while being pressed, thereby sliding with the lid portion 20. The relative position with respect to the portion 40 can be changed, and the length of the band portion 14 can be adjusted. According to this method of adjusting the length, it is only necessary to press the first convex portion 41C exposed to the operation window 20A and shift it in the longitudinal direction of the band portion 14, and to adjust the length of the middle terminal 2 by a simple and easy-to-understand operation. It can be performed.
Moreover, since the middle terminal 2 is a simple structure which connected the cover part 20 and the slide part 40, size reduction is easy and the decoration property of the band part 14 can be improved.

Further, in order to separate the first convex portion 41C or the second convex portion 41D from the edge 20B, it is necessary to elastically deform the pressing portion 41 with the support protrusion 49 as a fulcrum. Furthermore, as described above, the first convex portion 41C and the second convex portion 41D are configured such that the elevation angle of the slope on the edge 20B side is particularly large, so that the first convex portion 41C is not pressed. The edge 20B rarely climbs over the slopes of the first convex portion 41C and the second convex portion 41D. Therefore, the length of the band portion 14 does not change against the wearer's intention, and high stability and reliability can be ensured. Furthermore, since the height of the first convex portion 41C and the width of the top plane are larger than those of the second convex portion 41D, the band portion extends beyond the position where the inclined surface of the first convex portion 41C contacts the edge 20B. 14 cannot be shortened. For this reason, the length of the band part 14 does not change beyond the allowable range, and it is possible to sufficiently withstand an operation with an excessive force.
Further, since the first convex portion 41C and the second convex portion are exposed from the operation window 20A and the edge 20B is provided at the edge of the operation window 20A, the first convex portion 41C, the second convex portion and the edge 20B The engaged state can be visually recognized from the operation window 20A. For this reason, there exists an advantage that the state of the present length adjustment can be known easily.

In the middle end 2 of the first embodiment, two first convex portions 41C and second convex portions 41D that engage with the edge 20B are provided, and the length of the intermediate portion 2 can be adjusted in two stages. However, the present invention is not limited to this, and the number of convex portions arranged in the pressing portion 41 may be increased so that more lengths can be adjusted.
Moreover, in the middle end 2 of the first embodiment, one edge 20B is provided as an engaging portion, and a plurality of first convex portions 41C and second convex portions 41D are provided as protruding portions. However, the present invention is not limited to this, and a configuration using a plurality of engaging portions and one protruding portion may be used. Hereinafter, this case will be described as a second embodiment.

As shown in FIG. 12, the upper plate member 66 has a configuration in which an operation button 67 is erected on a flat plate-like member, and is disposed so as to overlap the lower plate member 61. One end of the upper plate member 66 is rounded into a cylindrical shape, and a spring bar accommodating portion 66A for allowing the spring bar 65 to pass therethrough is formed.
The operation button 67 is a round bar-shaped projection, and a narrower narrow portion 67B is formed between the proximal end portion 67A and the distal end portion 67C, and has a constricted shape. Since the distal end portion 67C receives a pressing operation by the wearer as will be described later, the corners are rounded to improve the operational feeling. The diameters of the base end portion 67A and the tip end portion 67C can be accommodated in the large diameter portions 52A and 52B of the Dalma hole 52 (FIG. 8) and exceed the width of the narrow width portion 52C. On the other hand, the diameter of the narrow portion 67B is smaller than the width of the narrow portion 52C.
As shown in FIG. 11, the lower plate member 61 and the upper plate member 66 are rotatably connected by a spring bar 65. A torsion coil spring 70 as an urging portion is passed through the spring bar 65, and the torsion coil spring 70 urges the lower plate member 61 and the upper plate member 66 in directions away from each other about the spring bar 65. Is done. As described above, the lower plate member 61 is connected to the lid portion 50 via the two spring bars 68 and 69, and is configured to restrict the tilting of the slide portion 60 relative to the lid portion 50. For this reason, the urging force of the torsion coil spring 70 acts in a direction in which the upper plate member 66 is pushed up from the lower plate member 61.

FIG. 13 is a cross-sectional view of a main part of the middle terminal 2A, and FIG. 14 is an enlarged cross-sectional view of a main part of the middle terminal 2A. In FIG. 13 and FIG. 14, the middle plate 25 and the upper band 15 are not shown.
In a state where the slide part 60 is attached to the lid part 50, the operation button 67 standing on the upper plate member 66 projects through the Dalma hole 52. Since the upper plate member 66 is pressed against the back surface of the flat plate portion 51 by the urging force of the torsion coil spring 70 (FIG. 11), the state where the operation button 67 protrudes from the Dharma hole 52 is maintained.

  Further, as shown in FIG. 13, the flat plate portion 51 has a shape in which the Dalma hole 52 and its periphery are recessed. The depth of the recess is sufficiently deeper than the protruding height of the operation button 67 protruding from the dharma hole 52. Therefore, the tip portion 67C does not protrude higher than the upper surface of the flat plate portion 51, and the operation button 67 protrudes when the wristwatch 1 is worn so that it does not hit the wearer's clothes or body.

  Since the long holes 61A and 61B of the slide part 60 are long holes extending in the longitudinal direction of the band part 14, the lid part 50 and the slide part 60 are within the range in which the spring bars 68 and 69 move in the long holes 61A and 61B. Can be moved relative to each other. However, since the base end portion 67A of the operation button 67 can be accommodated in the large diameter portions 52A and 52B and is thicker than the width of the narrow width portion 52C, in the state where the operation button 67 penetrates the large diameter portion 52B, the base end portion The portion 67A engages with the large diameter portion 52B and does not move. For this reason, the relative movement of the slide part 60 and the cover part 50 is controlled, and the length of the band part 14 is fixed.

Here, when the distal end portion 67 </ b> C of the operation button 67 receives a pressing operation, the upper plate member 66 is displaced downward against the urging force of the torsion coil spring 70 by this pressing force. Accordingly, the base end portion 67A is detached downward from the large diameter portion 52B, and the narrow width portion 67B is engaged with the large diameter portion 52B. In this state, since the narrow portion 67B is thinner than the width of the narrow portion 52C, the operation button 67 can be moved so that the narrow portion 67B passes through the narrow portion 52C, as shown in FIG. The entire slide part 60 moves together with the operation button 67 in the longitudinal direction of the band part 14. Since the base end portion 67A is thicker than the narrow width portion 52C, while the narrow width portion 67B passes through the narrow width portion 52C, even if there is no pressing force on the operation button 67, the base end portion 67A becomes the narrow width portion 52C. Never get in. For this reason, after the base end portion 67A is detached from the large diameter portion 52B, the operation button 67 can be moved even if the operation force is weakened.
When the operation button 67 reaches the large diameter portion 52A, the operation button 67 is naturally pushed up by the biasing force of the torsion coil spring 70, and the base end portion 67A enters the large diameter portion 52A. In this state, the base end portion 67A and the large diameter portion 52A are engaged to restrict the relative movement between the lid portion 50 and the slide portion 60, so that the length of the band portion 14 is fixed.

The length of the band portion 14 is different between the state where the base end portion 67A of the operation button 67 is engaged with the large diameter portion 52A and the state where the operation button 67 is engaged with the large diameter portion 52B. That is, the length of the band part 14 can be adjusted by pressing the operation button 67 and moving it in the longitudinal direction of the band part 14.
Thus, in the middle end 2A of the second embodiment, by moving the operation button 67 exposed from the dharma hole 52 provided in the lid portion 50 in the longitudinal direction of the band portion 14 while being pressed, The length of the band part 14 can be adjusted by changing the relative position of the lid part 50 and the slide part 60. In this method of adjusting the length, it is only necessary to press the operation button 67 exposed in the dharma hole 52 and shift it in the longitudinal direction of the band portion 14, and the length can be adjusted by a simple and easy-to-understand operation. In addition, when the operation button 67 is not pressed, the length of the band portion 14 is securely fixed, so that the length can be adjusted by a simple and easy-to-understand operation, and the adjusted length is reliably maintained. 2A can be provided.

  In addition, in the above-described middle end 2A of the second embodiment, the operation button 67 is engaged with either of the two large diameter portions 52A, 52B, and the length can be adjusted in two stages. The present invention is not limited to this, and a larger number of large diameter portions may be provided in the dharma hole 52 so that multi-stage length adjustment can be performed. In this case, if the adjacent large diameter portions are connected by the narrow width portion 52C, this can be easily realized. Moreover, in the middle terminal 2A according to the second embodiment, the displacement amount of the operation button 67 may be limited to an appropriate range. Hereinafter, this case will be described as a third embodiment.

[Third Embodiment]
FIG. 15 is a cross-sectional view of the main part showing the configuration of the middle terminal 2B according to the third embodiment. In FIG. 15, illustration of the middle plate 25 and the upper band 15 is omitted.
A middle dit 2B shown in FIG. 15 is obtained by providing an upper plate member 71 in place of the upper plate member 66 in the middle dit 2A according to the second embodiment. Similar to the upper plate member 66, the upper plate member 71 is a flat plate-like member provided with operation buttons 67, and is disposed so as to overlap the lower plate member 61.
One end of the upper plate member 71 is rounded into a cylindrical shape, and a spring bar accommodating portion 66A that allows the spring bar 65 to pass therethrough is formed. Further, the other end of the upper plate member 71 is bent at a substantially right angle toward the lower plate member 61 to form a displacement restricting portion 72. The distal end of the displacement restricting portion 72 is further bent at a substantially right angle to form a plane that faces the flat plate portion 62 of the lower plate member 61.

When the length is adjusted in the middle ring 2B shown in FIG. 15, the base end part 67A is separated from the large diameter parts 52A and 52B by pressing the operation button 67 in the same manner as the middle ring 2A. The operation button 67 is moved in the longitudinal direction of the band part 14.
If the pushing amount (displacement amount) of the operation button 67 is too large during this length adjustment operation, the distal end portion 67C may enter the large diameter portions 52A and 52B. In this case, since the diameter of the distal end portion 67C is larger than the width of the narrow width portion 52C, the movement of the operation button 67 is restricted by the distal end portion 67C, and the length cannot be adjusted. For this reason, it is necessary to stop the pressing operation and restore the displacement of the operation button 67.

In the middle end 2B according to the third embodiment, when the operation button 67 is pressed and displaced downward, the displacement restricting portion 72 approaches the flat plate portion 62 together with the displacement of the operation button 67. Then, when the base end portion 67A is completely separated from the large diameter portions 52A and 52B, or immediately after that, the displacement restricting portion 72 contacts the flat plate portion 62.
For this reason, since the amount of displacement of the operation button 67 when the operation button 67 is pressed is limited to an optimum amount for length adjustment, the operation button 67 is not pushed too much. Therefore, there is an advantage that the length can be adjusted reliably without paying attention to the force applied when pressing the operation button 67 or the amount of pressing. Further, since the member is not damaged even if the pressing force is too strong, the length can be adjusted with confidence.

  In the middle ends 2A and 2B according to the second and third embodiments, the torsion coil spring 70 is used to bias the operation button 67 toward the flat plate portion 51. However, the present invention is not limited thereto. Is not to be done. Hereinafter, a configuration for biasing the operation button 67 without using the torsion coil spring 70 will be described as a fourth embodiment.

[Fourth Embodiment]
FIG. 16 is a cross-sectional view of the main part showing the configuration of the middle ring 2C according to the fourth embodiment, and FIG. 17 is a perspective view showing the configuration of the upper plate member 75. In FIG. 16, illustration of the middle plate 25 and the upper band 15 is omitted.
The middle terminal 2C according to the fourth embodiment is obtained by disposing an upper plate member 75 in place of the upper plate member 66 in the middle terminal 2A according to the second embodiment. Similar to the upper plate member 66, the upper plate member 75 has a configuration in which an operation button 67 is erected on the flat plate portion 76, and is disposed so as to overlap the lower plate member 61.

At one end of the upper plate member 75, a spring bar accommodating portion 78 and an elastic support portion 79 as an urging portion are formed. The spring bar accommodating portion 78 is formed by winding the end of the upper plate member 75 in a cylindrical shape to allow the spring bar 65 to pass therethrough. The elastic support portions 79 are formed at both ends in the width direction of the upper plate member 75 so as to be arranged on both sides of the spring bar accommodating portion 78. The elastic support portion 79 is formed in a U-shaped cross section so as to form a space having substantially the same height as the spring rod accommodating portion 78 so that the spring rod 65 can be accommodated. The tip of the elastic support portion 79 is a flat plate that is substantially parallel to the flat plate portion 76 or that extends obliquely toward the flat plate portion 76.
Further, the other end of the upper plate member 75 is bent at a substantially right angle toward the lower plate member 61 to form a displacement restricting portion 77. The distal end of the displacement restricting portion 77 is further bent at a substantially right angle so as to be a flat surface facing the flat plate portion 62 of the lower plate member 61.
When the upper plate member 75 configured as described above is attached to the lower plate member 61, the torsion coil spring 70 is not required.

As shown in FIG. 16, when the upper plate member 75 is attached to the lower plate member 61 and connected to the lid portion 50, the operation button 67 is exposed from the Dalma hole 52, while the elastic support portion 79 is attached to the flat plate portion 62. Touching. Here, when the operation button 67 is pressed, the operation button 67 tends to be displaced downward, but since the elastic support portion 79 is in contact with the flat plate portion 62, the operation button 67 is displaced by the elasticity of the elastic support portion 79. Be disturbed. For this reason, only when the operation button 67 is pressed with a force sufficient to overcome the elasticity of the elastic support portion 79, the operation button 67 is displaced, and the length of the middle terminal 2 can be adjusted.
That is, the elastic support portion 79 has an effect of urging the operation button 67 so as to protrude from the dharma hole 52, similarly to the torsion coil spring 70 provided in the middle ring 2A according to the second embodiment.

Thus, in the case 2C according to the fourth embodiment, without using the torsion coil spring 70, the operation button 67 is urged to protrude from the Dharma hole 52, and the operation button 67 is pressed. A configuration is realized in which the length can be adjusted only in the case. According to this configuration, a reduction in cost can be expected due to a reduction in the number of parts and a reduction in assembly man-hours associated therewith.
In the second to fourth embodiments described above, the configuration in which the operation button 67 is always exposed on the upper surface of the lid portion constituting the middle ends 2A to 2C has been described. However, the present invention is not limited to this. For example, the operation button may be hidden when the length is not adjusted. Hereinafter, this case will be described as a fifth embodiment.

[Fifth Embodiment]
FIG. 18 is a cross-sectional view of the main part showing the configuration of the middle terminal 2D according to the fifth embodiment to which the present invention is applied. FIG. 19 is a main part perspective view showing the structure of the base part 100 constituting the middle ring 2D, and FIG. 20 is a main part perspective view showing the structure of the slide part 90. In FIG. 18, the middle plate 25 and the upper band 15 are not shown.
The middle end 2 of the fifth embodiment includes a lid portion 80 as a case instead of the lid portion 50 of the second to fourth embodiments described above, and the base portion 100 is disposed on the lid portion 80. The slide unit 90 as a moving member is connected to the base unit 100 so as to be relatively movable.
The intermediate plate 25 is rotatably connected to the lid portion 80 via a spring bar 35, and the base portion 100 is connected to the lid portion 80 by spring bars 98 and 99. In addition, the top piece of the upper band 15 is connected to the slide part 90 via the spring bar 39, and the slide part 90 and the base part 100 are relatively moved along the longitudinal direction of the band part 14, thereby The length of the band portion 14 can be adjusted by changing the length of the clamp 2D.

The lid portion 80 has a configuration in which side walls (not shown) are erected on both side ends of a substantially rectangular flat plate portion 81. In a space surrounded by the side walls and the flat plate portion 81, a button unit 30 and a base portion are provided. 100 and the slide part 90 are accommodated, and the end portions of the intermediate plate 25 and the upper band 15 enter.
The base portion 100 has a configuration in which side walls 103 and 104 are provided on both side ends of a substantially rectangular flat plate portion 101 extending in the longitudinal direction of the band portion 14. The center in the width direction of the flat plate portion 101 is a flat surface, and a dharma hole 102 as an engaging portion is formed in this flat surface.
The Dharma hole 102 is a hole composed of substantially circular large-diameter portions (holes) 102A and 102B, and a narrow-width portion 102C as a narrow-width opening that connects the large-diameter portion 102A and the large-diameter portion 102B. It penetrates to the back side of 101. The side walls 103 and 104 are formed with spring bar insertion holes 100A and 100B through which the spring bars 98 and 99 pass, respectively.

As shown in FIG. 20, the slide part 90 has a configuration in which a lower plate member 91 and an upper plate member 95 on which operation buttons 97 as rod-like bodies are erected are connected.
The lower plate member 91 has side walls 92 and 93 erected on both side ends of a flat plate, and a spring bar mounting hole 91 </ b> C is formed at one end of the side wall 92. Similarly, a spring bar mounting hole 91 </ b> C for mounting the spring bar is formed at one end of the side wall 92 facing the side wall 92. The lower plate member 91 is connected to the upper band 15 by attaching a spring bar (not shown) to the spring bar mounting holes 91C.
Long holes 91A and 91B extending in the longitudinal direction of the band portion 14 are formed in the side walls 92 and 93, respectively. A spring bar 98 is passed through the long hole 91A, and a spring bar 99 is passed through the long hole 91B. In addition, spring rod insertion holes 91 </ b> D are formed at end portions of the side walls 92 and 93. A spring bar 94 that rotatably connects the upper plate member 95 and the lower plate member 91 is fitted in the spring bar insertion hole 91D.

The upper plate member 95 is a plate in which an operation button 97 is erected, and is disposed on the upper side of the lower plate member 91. One end of the flat plate is rounded into a cylindrical shape to form a spring bar accommodating portion (not shown) through which the spring bar 94 passes. The other end of the flat plate is bent toward the lower plate member 91 to form a displacement restricting portion 96.
The operation button 97 is configured in the same manner as the operation button 67 described above. That is, the operation button 97 is a round bar-shaped protrusion, and a narrower width portion 97B having a narrower diameter is formed between the proximal end portion 97A and the distal end portion 97C, and has a constricted shape. The tip portion 97C has rounded corners to improve the operational feeling. The diameters of the proximal end portion 97A and the distal end portion 97C are sizes that can be accommodated in the large diameter portions 102A and 102B of the Dharma hole 102 (FIG. 19) and exceed the width of the narrow width portion 102C. On the other hand, the diameter of the narrow portion 97B is narrower than the width of the narrow portion 102C.
The lower plate member 91 and the upper plate member 95 are rotatably connected by the spring rod 94 described above. A torsion coil spring (not shown) is passed through the spring bar 94, and the upper plate member 95 is urged away from the lower plate member 91 by the torsion coil spring (not shown).

As shown in FIG. 18, the base portion 100 is disposed to face the back surface of the flat plate portion 81, and the slide portion 90 is accommodated in a space formed between the base portion 100 and the flat plate portion 81.
An operation button 97 erected on the upper plate member 95 of the slide portion 90 protrudes through a dharma hole 102 formed in the flat plate portion 101. As apparent from FIG. 18, the protruding direction of the operation button 97 is opposite to that of the middle ends 2 </ b> A to 2 </ b> C according to the second to fourth embodiments. Accordingly, when the middle terminal 2D is folded, the lower plate 27 overlaps the operation button 97, and the operation button 97 is hidden. As described above, the central portion of the flat plate portion 101 in which the Dalma hole 102 is formed is stepped from the periphery. The height of the step is sufficiently higher than the protruding height of the operation button 97 protruding from the dharma hole 102. For this reason, since the front end portion 97C is accommodated inside the step, the front end portion 97C does not contact the lower plate 27 when the middle retainer 2D is folded, and the folding operation of the middle retainer 2D is not hindered.

In the Dalma hole 102, the base end portion 97A of the operation button 97 enters the large diameter portion 102A or the large diameter portion 102B. Here, since the elongated holes 91A and 91B of the slide portion 90 are elongated holes extending in the longitudinal direction of the band portion 14, the slide portion 90 and the base are within the range in which the spring rods 98 and 99 move within the elongated holes 91A and 91B. The part 100 can be moved relative to each other.
However, as described above, the base end portion 97A of the operation button 97 can be accommodated in the large diameter portions 102A and 102B and is thicker than the width of the narrow width portion 102C. For this reason, when the base end portion 97A enters the large diameter portions 102A and 102B, the relative movement between the slide portion 90 and the base portion 100 is restricted, and the length of the band portion 14 is fixed.

Here, when the distal end portion 97C of the operation button 97 receives a pressing operation, the pressing force causes the upper plate member 95 to be displaced while rotating about the spring bar 94 against the biasing force of the torsion coil spring. To do. Here, the slide portion 90 is connected to the base portion 100 via two spring bars 98 and 99, and the tilt of the slide portion 90 relative to the base portion 100 is restricted. Therefore, the pressing force applied to the operation button 97 works to displace the upper plate member 95 toward the lower plate member 91, and the base end portion 97A of the operation button 97 is detached from the large diameter portion 102B by this displacement. In this state, the operation button 97 can be moved so that the narrow width portion 97B passes through the narrow width portion 102C, and the entire slide portion 90 moves in the longitudinal direction of the band portion 14 together with the operation button 97.
When the operation button 97 reaches the large diameter portion 102A, the operation button 97 is naturally pushed up by the biasing force of the torsion coil spring, and the base end portion 97A is fitted into the large diameter portion 102A. In this state, the base end portion 97 </ b> A and the large diameter portion 102 </ b> A are engaged to restrict the relative movement between the slide portion 90 and the base portion 100, so the length of the band portion 14 is fixed.
In this way, by pressing the operation button 97 and moving it in the longitudinal direction of the band portion 14, the length of the middle ring 2 </ b> D can be changed and the length of the band portion 14 can be adjusted.

As described above, in the middle end 2D of the fifth embodiment, the base portion 100 is fixed to the back surface side of the lid portion 80, and the slide portion 90 is connected to the base portion 100 so as to be relatively movable. . Then, while pressing the operation button 97 exposed from the Dharma hole 102 provided in the base part 100, by moving in the longitudinal direction of the band part 14, the relative position between the slide part 90 and the base part 100 is changed, The length of the band portion 14 can be adjusted by changing the length of the middle ring 2D. At the time of this length adjustment, it is only necessary to press the operation button 97 and shift it in the longitudinal direction of the band portion 14, and the length of the middle terminal 2 </ b> D can be adjusted by a simple and easy-to-understand operation.
Further, the operation button 97 is covered and hidden when the middle ring 2D is folded. In other words, since the operation button 97 is exposed only in the state in which the middle terminal 2D is opened, the length does not change accidentally at the time of wearing, and the erroneous operation is surely prevented, and high stability and reliability are ensured. It can be secured.
Furthermore, since the operation button 97 can be hidden when the length is not adjusted, the decorativeness of the band portion 14 can be improved.

  The detailed configuration of the wristwatch described in the first to fifth embodiments is arbitrary. For example, the upper band 15 and the lower band 16 are configured by connecting a number of frames made of a metal material. For example, a leather band such as a leather band or urethane / rubber may be used, and other detailed configurations can be appropriately changed. Furthermore, the present invention is not limited to the three-fold type middle ends described in the above embodiments, but can be widely applied to a two-fold type middle ends, double-open middle ends, and the like. In the above description, examples of applying the present invention to a wristwatch band have been described. However, the present invention can be widely applied to various belt-like accessories such as a bracelet, a necklace, a belt for clothes, and a belt for portable items such as bags.
