[0012] [First embodiment] A timepiece 100 according to a first embodiment of the present disclosure will now be described with reference to Figures 1 to 4. The timepiece 100 is an example of a wrist device worn on the wearer's wrist. FIG. 1 is a perspective view showing an outline of the main parts of a watch 100 of the first embodiment, FIG. 2 is an exploded perspective view showing an outline of the main parts of a band holding mechanism 1, FIG. 3 is a perspective view showing an outline of the main parts of the watch 100 seen from a different direction than FIG. 1, and FIG. 4 is a cross-sectional view showing an outline of the main parts of the band holding mechanism 1. 1, the watch 100 has a watch body 110 and a band 120. Note that the watch 100 is an example of a wrist device disclosed herein.

[0013] [Watch body] The watch body 110 has a case 111 and a lug 112 . The case 111 includes a case body 113, a bezel 114, a back cover 115, and a cover crystal (not shown). The case 113 is a cylindrical member made of metal, and houses the dial, movement, and other components (not shown) inside. Bezel 114 is a ring-shaped member made of metal and is located at the top of case 113. A cover crystal (not shown) is fixed to bezel 114. Back cover 115 is a member made of metal and is located to cover the opening on the lower side of case 113.

[0014] The lugs 112 are provided at the 6 o'clock and 12 o'clock positions on the case 113. Each lug 112 has a pair of retaining pieces 112A, 112B that protrude from the side of the case 113. The pair of retaining pieces 112A, 112B may have the same shape when viewed from above or from the side, or they may be different. A plan view refers to the shape when viewed from a direction perpendicular to the dial of the timepiece 100, and a side view refers to the shape when viewed from the 3 o'clock or 9 o'clock position on the timepiece 100.

[0015] The band 120 has a band body 122 formed by combining multiple metal links 121, and a first pin 123 that is provided at the end of the band body 122 that engages with the case 111 and extends in the width direction. In this embodiment, the first pin 123 is cylindrical. The first pin 123, together with the band holding device 10, constitutes the band holding mechanism 1 of the present disclosure. Furthermore, in this embodiment, the watch body 110 is equipped with a band holder 10. The watch body 110 is an example of a wrist device body of the present disclosure.

[0016] [Band holding device] The band holding device 10 is a device for connecting the band 120 to the case 111 of the watch body 110. In this embodiment, the band holding device 10 comprises a holding member 20 and an intermediate member 30.

[0017] [Holding member] The holding member 20 is configured to hold the band 120 by engaging with the first pin 123 of the band 120. In this embodiment, the holding member 20 has a holding member main body 21 and an elastic member 22. The holding member main body 21 is stored in a storage recess 313 of the intermediate member 30, which will be described later, and is supported by the intermediate member 30 by being fastened to the bottom surface of the storage recess 313 with a fastening member 33. As will be described later, the holding member main body 21 is configured to be movable between a fixed position and a detachable position with respect to the storage recess 313 of the intermediate member 30. In this embodiment, the holding member main body 21 has an abutment surface 211 that abuts against a first pin 123 that is inserted into an introduction groove 311 of the intermediate member 30, which will be described later. In addition, the holding member main body 21 is formed with a hole 212 through which the fastening member 33, which will be described later, is inserted.

[0018] The elastic member 22 is configured as a so-called coil spring. The elastic member 22 is stored in a storage recess 313 of the intermediate member 30, which will be described later. More specifically, the elastic member 22 is stored interposed between the holding member main body 21 and the bottom surface of the storage recess 313. In this way, the elastic member 22 is configured to bias the holding member main body 21 toward the back side of the timepiece 100.

[0019] [Intermediate parts] The intermediate member 30 supports the holding member 20 and is fixed to the case 111. In this embodiment, the intermediate member 30 has an intermediate member main body 31, a second pin 32, and a fastening member 33.

[0020] The intermediate member main body 31 is a metal member, and has an introduction groove 311, an insertion hole 312, and a storage recess 313 formed therein. The guide groove 311 is a groove into which the first pin 123 of the band 120 described above is inserted. In this embodiment, the guide groove 311 is formed so as to open onto the back side of the watch 100 in the intermediate member main body 31. The guide groove 311 has an opening 314 and a bottom 315 formed therein. As mentioned above, the opening 314 is open toward the back side of the watch 100 in the intermediate member main body 31. The opening 314 is an example of an opening in this disclosure. The bottom 315 is provided at the end of the guide groove 311 on the far side.

[0021] The insertion hole 312 is a hole into which the second pin 32 is inserted. In this embodiment, the insertion hole 312 is formed in the intermediary member main body 31 so as to penetrate the intermediary member main body 31 in the width direction. Similar to the guide groove 311, the storage recess 313 is formed so as to open on the back side of the watch 100 in the intermediate member main body 31. As mentioned above, the holding member main body 21 and elastic member 22 are stored in the storage recess 313.

[0022] The second pin 32 is configured as a so-called spring rod. The second pin 32 is inserted into the insertion hole 312 of the intermediate member main body 31 and is supported by the pair of holding pieces 112A, 112B of the can 112. This fixes the intermediate member 30 to the case 111. The fastening member 33 is configured as a so-called shoulder screw. The fastening member 33 is inserted through the hole 212 of the holding member main body 21 and is screwed into a screw hole (not shown) formed in the bottom surface of the storage recess 313. In this way, the fastening member 33 attaches the holding member main body 21 to the storage recess 313. At this time, the fastening member 33 attaches the holding member main body 21 to the storage recess 313 so that the holding member main body 21 can slide within the storage recess 313.

[0023] [Fixed and detached positions of the holding member] Next, the fixed position and detachable position of the holding member 20 will be described. FIG. 5 is a cross-sectional view showing the fixed position of the holding member 20, and FIG. 6 is a cross-sectional view showing the attachment / detachment position of the holding member 20. As shown in FIG. First, as shown in Fig. 5, in the normal state, the holding member main body 21 of the holding member 20 is biased by the elastic member 22, causing it to slide within the storage recess 313 toward the back side of the watch 100, in the first direction L1 shown in Fig. 5. In this state, in a cross-sectional view, part of the opening 314 of the guide groove 311 is covered by the holding member main body 21. In this disclosure, the position of the holding member 20 shown in Fig. 5 is referred to as the fixed position.

[0024] When the holding member main body 21 in this state is pressed toward the front side of the watch 100, the holding member main body 21 slides inside the storage recess 313 toward the front side of the watch 100, in the second direction L2 shown in Figure 6, as shown in Figure 6. In this state, in a cross-sectional view, the opening 314 of the introduction groove 311 is not covered by the holding member main body 21, and opens toward the back side of the watch 100. In this disclosure, the position of the holding member 20 shown in Figure 6 is referred to as the attachment / detachment position. Thus, in this embodiment, the holding member main body portion 21 of the holding member 20 is configured to be movable between a fixed position and a detachable position by sliding within the storage recess 313 in the first direction L1 and the second direction L2.

[0025] [How to attach and remove the band] Next, a method for attaching and detaching the band 120 of this embodiment will be described. 7 and 8 are cross-sectional views showing the state in which the band 120 is attached to the case 111. FIG. 7, when the first pin 123 of the band 120 is not inserted into the guide groove 311, that is, when the band 120 is not attached to the watch body 110, the holding member main body 21 is pressed in the second direction L2 to move the holding member main body 21 to the attachment / detachment position. Then, the first pin 123 is inserted from the opening 314 along the guide groove 311 toward the bottom 315.

[0026] 8, when the pressure on the holding member main body 21 is released with the first pin 123 inserted until it abuts against the bottom 315 of the guide groove 311, the holding member main body 21 is urged by the elastic member 22. This causes the holding member main body 21 to slide in the first direction L1 and move to the fixed position as shown in FIG. 4. Then, as described above, the opening 314 of the guide groove 311 is covered by the holding member main body 21, and the first pin 123 and the holding member main body 21 engage with each other. As a result, the first pin 123, while engaged with the holding member main body 21, cannot be removed from the guide groove 311, and the band 120 is attached to the watch body 110.

[0027] On the other hand, when removing the band 120 from the watch body 110, the wearer presses the holding member main body 21, causing it to slide in the second direction L2 from the state shown in Fig. 4. This moves the holding member main body 21 to the attachment / detachment position as shown in Fig. 8, allowing the first pin 123 to be moved along the guide groove 311 and pulled out from the opening 314.

[0028] In this way, in this embodiment, the holding member 20 that holds the band 120 is supported by the intermediate member 30 that is attached to the case 111, so it is sufficient to provide the first pin 123 that extends in the width direction at the end of the band 120. In other words, because the member that connects the band 120 to the watch body 110 is attached to the case 111, the member that is placed at the end of the band 120 can be made smaller, and the number of parts can be reduced.

[0029] In this embodiment, the abutment surface 211 of the retaining member main body 21 is inclined relative to the insertion direction of the first pin 123, i.e., the direction in which the introduction groove 311 opens, so that the first pin 123 can be inserted into the introduction groove 311 and the band 120 can be attached to the watch body 110 without pressing the retaining member main body 21. That is, when the first pin 123 is inserted into the introduction groove 311 while the holding member main body 21 is in the fixed position, the first pin 123 comes into contact with the contact surface 211 of the holding member main body 21. In this embodiment, the contact surface 211 is inclined toward the insertion direction of the first pin 123 so that the holding member main body 21 slides in the second direction L2. Therefore, when the first pin 123 is further inserted toward the bottom 315 of the introduction groove 311 in this state, the first pin 123 presses against the contact surface 211, causing the holding member main body 21 to slide in the second direction L2. This moves the holding member main body 21 to the attachment / detachment position, allowing the wearer to attach the band 120 to the watch body 110 without having to press the holding member main body 21.

[0030] [Effects of the first embodiment] According to the first embodiment, the following effects can be obtained. In this embodiment, the holding member 20, which holds the band 120 by engaging with the first pin 123, is supported by the intermediate member 30 attached to the case 111, so it is sufficient to provide the first pin 123 extending in the width direction at the end of the band 120. This makes it possible to reduce the size of the members disposed at the end of the band 120 and the number of parts.

[0031] In this embodiment, the first pin 123 can be inserted into the guide groove 311 provided in the intermediate member 30 to engage with the holding member 20, so that the band 120 can be easily attached to the case 111.

[0032] In this embodiment, by moving the holding member 20 between a fixed position and a detachable position, the first pin 123 can be engaged with the holding member 20 or removed from the guide groove 311, thereby making it possible to easily attach and detach the band 120 to and from the case 111.

[0033] In this embodiment, the abutment surface 211 of the holding member 20 is inclined with respect to the insertion direction of the first pin 123, so that the first pin 123 can be inserted into the guide groove without operating the holding member 20, and the first pin 123 can be engaged with the holding member 20. This makes it easy to attach the band 120.

[0034] [Second embodiment] Next, a timepiece 100A according to a second embodiment of the present invention will be described with reference to FIGS. The band holding device 10A of the second embodiment differs from the first embodiment in that a holding member 20A is rotatably supported by an intermediate member 30A. In the second embodiment, the same or similar components as those in the first embodiment are denoted by the same reference numerals, and descriptions thereof will be omitted.

[0035] FIG. 9 is an exploded perspective view showing an outline of the main parts of a band holding mechanism 1A according to the second embodiment, and FIG. 10 is a cross-sectional view showing the main parts of the band holding mechanism 1A. 9 and 10, similar to the first embodiment described above, band 120 has a first pin 123 that is provided at the end on the side that engages with case 111 and extends in the width direction. Note that first pin 123, together with band holding device 10A, constitutes band holding mechanism 1A of the present disclosure.

[0036] [Band holding device] The band holding device 10A is a device for connecting the band 120 to the case 111 of the watch body 110A. In this embodiment, the band holding device 10A includes a holding member 20A and an intermediate member 30A.

[0037] [Holding member] Similar to the first embodiment described above, the holding member 20A is configured to hold the band 120 by engaging with the first pin 123 of the band 120. In this embodiment, the holding member 20A has a holding member main body 21A and an elastic member 22A. The holding member main body 21A is supported by a spring pin 32A of the intermediate member 30A (described later), and is thereby rotatably supported by the intermediate member 30A. As described later, the holding member main body 21A is configured to be movable between a fixed position and a detachable position. In this embodiment, the holding member main body 21A has an abutment surface 211A that abuts against a first pin 123 that is inserted into an introduction groove 311A of the intermediate member 30A (described later). Furthermore, the holding member main body 21A is provided with a hole 212A through which the spring pin 32A (described later) is inserted, an engagement portion 213A that engages with the first pin 123, and an operation portion 214A that is operated by the wearer.

[0038] Elastic member 22A is configured as a so-called torsion coil spring, with one end of the coil locked to intermediate member 30A and the other end attached to holding member main body 21A. In this embodiment, elastic member 22A is configured to bias holding member main body 21A so that engaging portion 213A of holding member main body 21A rotates in a direction away from case 111.

[0039] [Intermediate parts] The intermediate member 30A supports the holding member 20A and is fixed to the case 111. In this embodiment, the intermediate member 30A has an intermediate member main body 31A, a spring pin 32A, and a cylindrical member 33A.

[0040] The intermediate member main body 31A is a metal member, and is formed with an introduction groove 311A and an insertion hole 312A. As with the first embodiment described above, the guide groove 311A is a groove into which the first pin 123 of the band 120 is inserted. In this embodiment, the guide groove 311A is formed so as to open onto the back side of the watch 100A in the intermediate member main body 31A. The guide groove 311A is formed with an opening 314A and a bottom 315A. As mentioned above, the opening 314A is open toward the back side of the timepiece 100A in the intermediate member main body 31A. Note that the opening 314A is an example of an opening in this disclosure. The bottom portion 315A is provided at the end portion on the far side of the introduction groove 311A.

[0041] The insertion hole 312A is a hole into which the spring pin 32A and the cylindrical member 33A are inserted. In this embodiment, the insertion hole 312A is formed in the intermediate member main body 31A so as to penetrate through the intermediate member main body 31A in the width direction. The spring pin 32A and the cylindrical member 33A are inserted into the hole 212A of the holding member main body 21A and the insertion hole 312A of the intermediate member main body 31A. Specifically, the spring pin 32A is inserted into the inner periphery of the cylindrical member 33A, and in this state, the spring pin 32A and the cylindrical member 33A are inserted into the insertion hole 312A of the intermediate member main body 31A. This allows the holding member main body 21A to be rotatably supported by the intermediate member 30A. Furthermore, the spring pin 32A is supported by a pair of holding pieces 112A, 112B of the can 112. This allows the intermediate member 30A to be fixed to the case 111.

[0042] Thus, in this embodiment, spring pin 32A rotatably supports holding member main body 21A and fixes intermediate member main body 31A to case 111. That is, spring pin 32A constitutes the second pin and third pin of the present disclosure. As a result, spring pin 32A serves both as the second pin that rotatably supports holding member 20A and the third pin that fixes intermediate member 30A to the case, thereby reducing the number of parts.

[0043] [Fixed and detached positions of the holding member] Next, the fixed position and the detachable position of the holding member 20A will be described. FIG. 11 is a cross-sectional view showing the fixed position of the holding member 20A, and FIG. 12 is a cross-sectional view showing the attachment / detachment position of the holding member 20A. First, as shown in Fig. 11, in the normal state, the holding member main body 21A of the holding member 20A is biased by the elastic member 22A and rotates in the direction in which the holding member main body 21A moves away from the watch body 110A, in the first direction R1 shown in Fig. 11. In this state, in a cross-sectional view, the opening 314A of the guide groove 311A is covered by the engagement portion 213A of the holding member main body 21A. In this disclosure, the position of the holding member 20A shown in Fig. 11 is referred to as the fixed position.

[0044] When the operating section 214A of the holding member main body 21A in this state is pressed toward the back side of the watch 100A, the engaging section 213A of the holding member main body 21A rotates toward the watch body 110A, in the second direction R2 shown in Fig. 12, as shown in Fig. 12. In this state, in a cross-sectional view, the opening 314A of the introduction groove 311A is not covered by the engaging section 213A of the holding member main body 21A, and opens toward the back side of the watch 100A. In this disclosure, the position of the holding member 20A shown in Fig. 12 is referred to as the attachment / detachment position. As described above, in this embodiment, the holding member main body 21A of the holding member 20A is configured to be movable between the fixed position and the detachable position by rotating in the first direction R1 and the second direction R2.

[0045] [How to attach and remove the band] Next, a method for attaching and detaching the band 120 of this embodiment will be described. 13 and 14 are cross-sectional views showing the state in which the band 120 is attached to the case 111. FIG. 13, when the first pin 123 of the band 120 is not inserted into the guide groove 311A, that is, when the band 120 is not attached to the watch body 110A, the operating part 214A of the holding member main body 21A is pressed in the second direction R2 to move the holding member main body 21A to the attachment / detachment position. Then, the first pin 123 is inserted from the opening 314A along the guide groove 311A toward the bottom 315A.

[0046] 14, when the pressure on the operating portion 214A of the holding member main body 21A is released with the first pin 123 inserted until it abuts against the bottom portion 315A of the guide groove 311A, the holding member main body 21A is biased by the elastic member 22A. This causes the holding member main body 21A to rotate in the first direction R1 and move to the fixed position as shown in FIG. 10. Then, as described above, the opening 314A of the guide groove 311A is covered by the engaging portion 213A of the holding member main body 21A, and the first pin 123 engages with the engaging portion 213A of the holding member main body 21A. As a result, the first pin 123, while engaged with the engaging portion 213A of the holding member main body 21A, cannot be removed from the guide groove 311A, and the band 120 is attached to the watch body 110A.

[0047] On the other hand, when removing band 120 from watch body 110A, the wearer rotates holding member main body 21A in second direction R2 by pressing operating portion 214A of holding member main body 21A from the state shown in Fig. 10. This moves holding member main body 21A to the attachment / detachment position as shown in Fig. 13, and first pin 123 can be moved along guide groove 311A and pulled out from opening 314A.

[0048] Thus, in this embodiment, as in the first embodiment described above, the holding member 20A that holds the band 120 is supported by the intermediate member 30A attached to the case 111, so it is sufficient to provide the first pin 123 extending in the width direction at the end of the band 120. In other words, because the member that connects the band 120 to the watch body 110A is attached to the case 111, the member placed at the end of the band 120 can be made smaller and the number of parts can be reduced. In addition, in this embodiment, the intermediate member 30A has the spring pin 32A that rotatably supports the holding member 20A, so that the holding member 20A can be rotatably supported between the fixed position and the detachable position.

[0049] In this embodiment, as in the first embodiment described above, the abutment surface 211A of the retaining member main body 21A is inclined with respect to the insertion direction of the first pin 123, i.e., the direction in which the introduction groove 311A opens, so that the first pin 123 can be inserted into the introduction groove 311 and the band 120 can be attached to the watch body 110A without pressing the retaining member main body 21A.

[0050] [Effects of the second embodiment] According to the second embodiment, the following effects can be obtained. In this embodiment, the intermediate member 30A has a spring pin 32A that rotatably supports the holding member 20A, and therefore, the holding member 20A can be rotatably supported between the fixed position and the detachable position.

[0051] In this embodiment, the intermediate member 30A is attached to the case 111 by the spring rod 32A, so that the intermediate member 30A can be easily fixed to the case 111.

[0052] In this embodiment, the spring pin 32A rotatably supports the holding member 20A and also fixes the intermediate member 30A to the case 111, thereby reducing the number of parts.

[0053] [Variations] The present disclosure is not limited to the above-described embodiments, and includes modifications, improvements, etc. within the scope of achieving the object of the present disclosure. FIG. 15 is a cross-sectional view showing the outline of the main parts of a modified band holding mechanism 1B, and FIG. 16 is a rear view showing the main parts of a modified timepiece 100B. As shown in Figures 15 and 16, band holding device 10B, which constitutes band holding mechanism 1B of the modified example, is equipped with holding member 20B and intermediate member 30B. Intermediate member 30B is equipped with intermediate member main body 31B, which is provided with engagement portion 213B and operating portion 214B, as in the second embodiment described above. Furthermore, intermediate member main body 31B of the modified example is provided with lid portion 215B that covers the back side of watch body 110B of intermediate member main body 31B. As a result, the back side of intermediate member main body 31B is covered by the lid portion, which prevents part of first pin 123 from being exposed, improving the design.

[0054] FIG. 17 is a perspective view showing the outline of the main parts of a timepiece 100C of another modified example. In the first and second embodiments described above, the band 120C has a band main body 122C configured by combining multiple metal links 121, but this is not limited to this. For example, as shown in Fig. 17, the band main body 122C may be made of leather, cloth, synthetic resin, or the like.

[0055] FIG. 18 is an exploded perspective view showing an outline of the main parts of a band holding mechanism 1D according to yet another modified example. As shown in Figure 18, the band holding device 10D that makes up the band holding mechanism 1D of a modified timepiece 100D is equipped with a holding member 20D and an intermediate member 30D. An intermediate member main body 31D of the intermediate member 30D is formed integrally with the case 111 of the watch body 110D. This eliminates the need for spring rods or the like to attach the intermediate member main body 31D to the case 111, reducing the number of parts.

[0056] In the second embodiment, the spring pin 32A serves both as the second pin that supports the holding member 20A and as the third pin that fixes the intermediate member 30A to the case 111, but is not limited to this. For example, the second pin that supports the holding member and the third pin that fixes the intermediate member to the case may be provided separately.

[0057] In the above embodiments, the first pin 123 is cylindrical. However, this is not limiting. For example, the first pin may be shaped like an elliptical cylinder or a polygonal cylinder. This configuration allows the attachment angle of the band to the intermediate member to be set as desired. Furthermore, the present disclosure also includes cases where the first pin has a cylindrical or polygonal cylindrical shape.

[0058] In the above embodiments, watches 100, 100A, 100B, 100C, and 100D are used as examples of wrist devices, but the present disclosure is not limited to these. For example, the present disclosure can be applied to wrist devices such as pulse monitors and bands attached to such wrist devices. Furthermore, watches 100, 100A, 100B, 100C, and 100D as wrist devices can be applied to any watch that is worn on the wearer's wrist using a band, regardless of whether it is a so-called digital watch or an analog watch.

[0059] Summary of this disclosure The band holding mechanism of the present disclosure is characterized by comprising a band having a first pin extending in the width direction at the end on the side that engages with the case, a holding member that holds the band by engaging with the first pin, and an intermediate member that supports the holding member and is attached to the case or is formed integrally with the case. As a result, the holding member that holds the band by engaging with the first pin is attached to the case or is supported by an intermediate member that is integral with the case, so it is only necessary to provide the first pin extending in the width direction at the end of the band, which makes it possible to reduce the size of the members placed at the end of the band and the number of parts.

[0060] In the band holding mechanism of the present disclosure, the intermediary member may have an introduction groove into which the first pin can be inserted, and the first pin may be inserted into the introduction groove to engage with the holding member. With this, by inserting the first pin into the guide groove provided in the intermediate member, the first pin and the holding member can be engaged, so that the band can be easily attached to the case.

[0061] In the band holding mechanism of the present disclosure, the intermediary member may movably support the holding member between a fixed position in which the first pin is fixed to the guide groove and a detachable position in which the first pin inserted into the guide groove can be removed. This allows the first pin to be engaged with the holding member or removed from the guide groove by moving the holding member between the fixed position and the detachable position, making it possible to easily attach and detach the band to and from the case.

[0062] In the band holding mechanism disclosed herein, the holding member has an abutment surface that abuts against the first pin inserted into the introduction groove from the opening of the introduction groove, and the abutment surface may be inclined with respect to the insertion direction of the first pin so that when the first pin is further inserted into the introduction groove while the first pin and the abutment surface are in abutment, the holding member moves toward the attachment / detachment position. As a result, the abutment surface of the holding member is inclined relative to the insertion direction of the first pin, so the first pin can be inserted into the guide groove without operating the holding member, and the first pin can be engaged with the holding member, making the band attachment operation easier.

[0063] In the band holding mechanism of the present disclosure, the intermediate member may have a second pin that rotatably supports the holding member. This allows the intermediate member to support the holding member so that it can rotate between the fixed position and the detachable position.

[0064] In the band holding mechanism of the present disclosure, the intermediate member may have a third pin for attachment to the case. This allows the intermediate member to be easily fixed to the case.

[0065] In the band holding mechanism of the present disclosure, the intermediate member may have spring rods that constitute the second pin and the third pin. As a result, the spring pin serves both as a second pin that rotatably supports the holding member and as a third pin that fixes the intermediate member to the case, making it possible to reduce the number of parts.

[0066] The wrist device disclosed herein is characterized by comprising a case, a band having a first pin extending widthwise at an end of the engagement side with the case, a holding member that holds the band by engaging with the first pin, and an intermediate member that supports the holding member and is attached to the case or formed integrally with the case.

[0067] The wrist device main body of the present disclosure is characterized by comprising a case, a holding member that holds the band by engaging with a first pin on the band, and an intermediate member that supports the holding member and is attached to the case or formed integrally with the case.

[0068] The band holding device of the present disclosure is characterized by comprising a holding member that holds the band by engaging with a first pin carried by the band, and an intermediate member that supports the holding member and is attached to a case or formed integrally with the case.

[0069] The band of the present disclosure is characterized by having a first pin extending widthwise at the end on the side that engages with the case, a retaining member that engages with the first pin, and being connected to the case by an intermediate member that supports the retaining member and is attached to the case or is integrally formed with the case.
