In the present embodiment, the first pin 123 is cylindrical. In addition, the first pin 123 and the band holding device 10 together constitute the band holding mechanism 1 of the present disclosure.

[0042] Moreover, in the present embodiment, the clock main body 110 includes a band holding device 10. Additionally, the clock main body 110 is an example of the main body portion of the wrist-worn device of the present disclosure.

[0043] (Band holding device)

[0044] The band holding device 10 is a device for connecting the band 120 to the housing 111 of the clock main body 110. In the present embodiment, the band holding device 10 includes a holding member 20 and an adapter member 30.

[0045] (Holding member)

[0046] The holding member 20 is configured to hold the band 120 by engaging with the first pin 123 of the band 120. In the present embodiment, the holding member 20 has a holding member main body portion 21 and an elastic member 22.

[0047] The holding member main body portion 21 is housed in a housing recess 313 of the adapter member 30 described later and is fastened to the bottom surface of the housing recess 313 by a fastening member 33, thereby being supported by the adapter member 30. Moreover, as described later, the holding member main body portion 21 is configured to be movable relative to the housing recess 313 of the adapter member 30 between a fixed position and a loading / unloading position. In the present embodiment, the holding member main body portion 21 has a contact surface 211 that contacts the first pin 123 inserted into an introduction groove 311 of the adapter member 30 described later. Additionally, a hole portion 212 is formed in the holding member main body portion 21 through which the fastening member 33 described later is inserted.

[0048] The elastic member 22 is configured as a so-called spiral spring. Moreover, the elastic member 22 is housed in the housing recess 313 of the adapter member 30 described later. More specifically, the elastic member 22 is sandwiched and housed between the holding member main body portion 21 and the bottom surface of the housing recess 313. Thereby, the elastic member 22 is configured to apply a force to the holding member main body portion 21 toward the back side of the clock 100.

[0049] (Adapter member)

[0050] The adapter member 30 supports the holding member 20 and is fixed to the housing 111. In the present embodiment, the adapter member 30 has an adapter member main body portion 31, a second pin 32, and a fastening member 33.

[0051] The adapter member main body portion 31 is a metal component and is formed with an introduction groove 311, an insertion hole 312, and a housing recess 313.

[0052] The insertion groove 311 is a groove into which the first pin 123 of the aforementioned belt 120 is inserted. In the present embodiment, the insertion groove 311 is formed to open on the back side of the adapter member main body portion 31 closer to the timepiece 100. Further, an opening portion 314 and a bottom portion 315 are formed in the insertion groove 311.

[0053] As described above, the opening portion 314 opens on the back side of the adapter member main body portion 31 closer to the timepiece 100. Further, the opening portion 314 is an example of the opening of the present disclosure.

[0054] The bottom portion 315 is provided at the inner end of the insertion groove 311.

[0055] The insertion hole 312 is a hole into which the second pin 32 is inserted. In the present embodiment, the insertion hole 312 is formed in the adapter member main body portion 31 so as to penetrate in the width direction of the adapter member main body portion 31.

[0056] The storage recess 313 is formed to open on the back side of the adapter member main body portion 31 closer to the timepiece 100 in the same manner as the insertion groove 311. Further, as described above, the holding member main body portion 21 and the elastic member 22 are stored in the storage recess 313.

[0057] The second pin 32 is configured as a so-called spring rod. Further, it is inserted into the insertion hole 312 of the adapter member main body portion 31 and is supported by a pair of holding piece portions 112A and 112B of the lug 112. Thereby, the adapter member 30 is fixed to the housing 111.

[0058] The fastening member 33 is configured as a so-called stepped screw. Further, the fastening member 33 is inserted through the hole portion 212 of the holding member main body portion 21 and is screwed into a threaded hole (not shown) formed in the bottom surface of the storage recess 313. Thereby, the fastening member 33 attaches the holding member main body portion 21 to the storage recess 313. At this time, the fastening member 33 attaches the holding member main body portion 21 to the storage recess 313 in such a manner that the holding member main body portion 21 can slide within the storage recess 313.

[0059] (Fixing position and loading / unloading position of the holding member)

[0060] Next, the fixing position and the loading / unloading position of the holding member 20 will be described.

[0061] Figure 5 is a cross-sectional view showing the fixing position of the holding member 20, Figure 6 is a cross-sectional view showing the loading / unloading position of the holding member 20.

[0062] First, as Figure 5As shown, in the normal state, the holding member main body 21 of the holding member 20 is biased by the elastic member 22, so as to slide in the receiving recess 313 toward the back side of the timepiece 100, Figure 5 in the first direction L1 shown. In this state, in a cross-sectional view, a part of the opening 314 of the introduction groove 311 is covered by the holding member main body 21. In the present disclosure, the Figure 5 position of the holding member 20 shown is referred to as the fixed position.

[0063] Moreover, when the holding member main body 21 in this state is pressed toward the front side of the timepiece 100, as Figure 6 shown, the holding member main body 21 slides in the receiving recess 313 toward the front side of the timepiece 100, Figure 6 in the second direction L2 shown. 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, but opens toward the back side of the timepiece 100. In the present disclosure, the Figure 6 position of the holding member 20 shown is referred to as the attachment / detachment position.

[0064] Thus, in the present embodiment, the holding member main body 21 of the holding member 20 is configured to be movable between the fixed position and the attachment / detachment position by sliding in the receiving recess 313 toward the first direction L1 and the second direction L2.

[0065] (Method for attaching and detaching the band)

[0066] Next, a method for attaching and detaching the band 120 of the present embodiment will be described.

[0067] Figure 7 、 Figure 8 is a cross-sectional view showing a state where the band 120 is attached to the housing 111.

[0068] First, as Figure 7 shown, in a state where the first pin 123 of the band 120 is not inserted into the introduction groove 311, that is, in a state where the band 120 is not attached to the timepiece main body 110, by pressing the holding member main body 21 toward the second direction L2, the holding member main body 21 is moved to the attachment / detachment position. Then, the first pin 123 is inserted from the opening 314 along the introduction groove 311 toward the bottom 315.

[0069] Then, as Figure 8 shown, in a state where the first pin 123 is inserted until it abuts against the bottom 315 of the introduction groove 311, when the pressing of the holding member main body 21 is released, the holding member main body 21 is biased by the elastic member 22. Then, the holding member main body 21 slides toward the first direction L1, so that as Figure 4is moved to a fixed position. Also, as described above, the opening 314 of the insertion groove 311 is covered by the holding member main body 21, and the first pin 123 is engaged with the holding member main body 21. Thus, in a state where the first pin 123 is engaged with the holding member main body 21, the first pin 123 does not come out of the insertion groove 311, so that the band 120 is attached to the watch main body 110.

[0070] On the other hand, when detaching the band 120 from the watch main body 110, the wearer presses the holding member main body 21 from the Figure 4 state shown in FIG., so that the holding member main body 21 slides in the second direction L2. Thus, as Figure 8 shown in FIG., the holding member main body 21 is moved to the attachment / detachment position, so that the first pin 123 can be moved along the insertion groove 311 and pulled out from the opening 314.

[0071] Thus, in the present embodiment, since the holding member 20 that holds the band 120 is supported by the adapter member 30 attached to the case 111, it is only necessary to provide the first pin 123 extending in the width direction at the end of the band 120. That is, since the member that connects the band 120 to the watch main body 110 is attached to the case 111, the member disposed at the end of the band 120 can be miniaturized and the number of components can be reduced.

[0072] In addition, in the present embodiment, the contact surface 211 of the holding member main body 21 is inclined with respect to the insertion direction of the first pin 123, that is, the direction in which the insertion groove 311 opens. Therefore, even if the holding member main body 21 is not pressed, the first pin 123 can be inserted into the insertion groove 311 to attach the band 120 to the watch main body 110.

[0073] That is, in a state where the holding member main body 21 is located at the fixed position, when the first pin 123 is inserted into the insertion groove 311, the first pin 123 abuts against the contact surface 211 of the holding member main body 21. Here, in the present embodiment, the contact surface 211 is inclined in the insertion direction of the first pin 123 so that the holding member main body 21 slides in the second direction L2. Therefore, in this state, when the first pin 123 is further inserted toward the bottom 315 of the insertion groove 311, the contact surface 211 is pressed by the first pin 123, and the holding member main body 21 slides in the second direction L2. Thus, the holding member main body 21 is moved to the attachment / detachment position, so that the wearer can attach the band 120 to the watch main body 110 even without pressing the holding member main body 21.

[0074] (Function and Effect of the First Embodiment)

[0075] According to such a first embodiment, the following effects can be obtained.

[0076] In the present embodiment, the holding member 20 that holds the belt 120 by engaging with the first pin 123 is supported by the adapter member 30 attached to the housing 111. Therefore, it is only necessary to provide the first pin 123 extending in the width direction at the end of the belt 120. As a result, the components arranged at the end of the belt 120 can be miniaturized, and the number of components can be reduced.

[0077] In the present embodiment, by inserting the first pin 123 into the insertion groove 311 provided in the adapter member 30, the first pin 123 can be engaged with the holding member 20. Therefore, the belt 120 can be easily attached to the housing 111.

[0078] In the present embodiment, by moving the holding member 20 between the fixed position and the loading / unloading position, the first pin 123 can be engaged with the holding member 20, or the first pin 123 can be removed from the insertion groove 311. Therefore, the belt 120 can be easily loaded and unloaded with respect to the housing 111.

[0079] In the present embodiment, the contact surface 211 of the holding member 20 is inclined with respect to the insertion direction of the first pin 123. Therefore, the first pin 123 can be inserted into the insertion groove and engaged with the holding member 20 without operating the holding member 20. As a result, the installation operation of the belt 120 can be easily performed.

[0080] (Second Embodiment)

[0081] Next, Figures 9 to 14 the clock 100A according to the second embodiment of the present invention will be described.

[0082] The belt holding device 10A of the second embodiment is different from the above-described first embodiment in that the holding member 20A is rotatably supported by the adapter member 30A. In addition, in the second embodiment, the same reference numerals are assigned to the same or similar structures as those in the first embodiment, and the description thereof is omitted.

[0083] Figure 9 is a schematic exploded perspective view showing the main part of the belt holding mechanism 1A of the second embodiment, Figure 10 is a cross-sectional view showing the main part of the belt holding mechanism 1A.

[0084] As Figure 9 、 Figure 10 shown, the belt 120 is the same as that in the aforementioned first embodiment, and has the first pin 123 provided at the engaging side end engaged with the housing 111 and extending in the width direction. In addition, the first pin 123 and the belt holding device 10A together constitute the belt holding mechanism 1A of the present disclosure.

[0085] (Belt Holding Device)

[0086] The band holding device 10A is a device for connecting the band 120 to the case 111 of the watch body 110A. In the present embodiment, the band holding device 10A includes a holding member 20A and an adapter member 30A.

[0087] (Holding member)

[0088] The holding member 20A is configured to hold the band 120 by engaging with the first pin 123 of the band 120, similarly to the first embodiment described above. In the present embodiment, the holding member 20A has a holding member main body portion 21A and an elastic member 22A.

[0089] The holding member main body portion 21A is supported by a spring rod 32A of the adapter member 30A described later, and thus is supported by the adapter member 30A so as to be rotatable. And, as will be described later, the holding member main body portion 21A is configured to be movable between a fixed position and a loading / unloading position. In the present embodiment, the holding member main body portion 21A has an abutting surface 211A that abuts against the first pin 123 inserted into an introduction groove 311A of the adapter member 30A described later. And, a hole portion 212A through which the spring rod 32A described later is inserted, an engaging portion 213A that engages with the first pin 123, and an operation portion 214A for the wearer to operate are provided in the holding member main body portion 21A.

[0090] The elastic member 22A is configured as a so-called torsion spiral spring, one end portion of the coil is fixed to the adapter member 30A, and the other end portion is attached to the holding member main body portion 21A. And, in the present embodiment, the elastic member 22A is configured to apply a force to the holding member main body portion 21A so that the engaging portion 213A of the holding member main body portion 21A rotates in a direction away from the case 111.

[0091] (Adapter member)

[0092] The adapter member 30A supports the holding member 20A and is fixed to the case 111. In the present embodiment, the adapter member 30A has an adapter member main body portion 31A, a spring rod 32A, and a cylindrical member 33A.

[0093] The adapter member main body portion 31A is a metal member, and an introduction groove 311A and an insertion hole 312A are formed therein.

[0094] The introduction groove 311A is a groove into which the first pin 123 of the band 120 is inserted, similarly to the first embodiment described above. In the present embodiment, the introduction groove 311A is formed to open on the back side of the adapter member main body portion 31A closer to the watch 100A. Moreover, an opening portion 314A and a bottom portion 315A are formed in the introduction groove 311A.

[0095] As described above, the opening 314A opens toward the back side of the adapter member main body 31A near the timepiece 100A. Further, the opening 314A is an example of the opening of the present disclosure.

[0096] The bottom 315A is provided at the inner end of the introduction groove 311A.

[0097] The insertion hole 312A is a hole into which the spring rod 32A and the cylindrical member 33A are inserted. In the present embodiment, the insertion hole 312A is formed in the adapter member main body 31A so as to penetrate in the width direction of the adapter member main body 31A.

[0098] The spring rod 32A and the cylindrical member 33A are inserted into the hole portion 212A of the holding member main body 21A and the insertion hole 312A of the adapter member main body 31A. Specifically, the spring rod 32A is inserted into the inner peripheral side of the cylindrical member 33A, and the spring rod 32A and the cylindrical member 33A in this state are inserted into the insertion hole 312A of the adapter member main body 31A. Thus, the holding member main body 21A is supported by the adapter member 30A so as to be rotatable. Further, the spring rod 32A is supported by a pair of holding piece portions 112A, 112B of the lug 112. Thus, the adapter member 30A is fixed to the housing 111.

[0099] Thus, in the present embodiment, the spring rod 32A supports the holding member main body 21A so as to be rotatable and fixes the adapter member main body 31A to the housing 111. That is, the spring rod 32A constitutes the second pin and the third pin of the present disclosure. Accordingly, the spring rod 32A serves as both the second pin that supports the holding member 20A so as to be rotatable and the third pin that fixes the adapter member 30A to the housing, and thus the number of components can be reduced.

[0100] (Fixing position and loading / unloading position of the holding member)

[0101] Next, the fixing position and the loading / unloading position of the holding member 20A will be described.

[0102] Figure 11 is a cross-sectional view showing the fixing position of the holding member 20A, Figure 12 is a cross-sectional view showing the loading / unloading position of the holding member 20A.

[0103] First, as Figure 11 shown, in a normal state, the holding member main body 21A of the holding member 20A is biased by the elastic member 22A so as to rotate in a first direction R1, which is a direction in which the holding member main body 21A moves away from the timepiece main body 110A. Figure 11 shown, in this state, in a cross-sectional view, the opening 314A of the introduction groove 311A is covered by the engaging portion 213A of the holding member main body 21A. In the present disclosure,Figure 11 The position of the holding member 20A shown is referred to as the fixed position.

[0104] Moreover, when the operation portion 214A of the holding member main body portion 21A in this state is pressed toward the back side of the timepiece 100A, as Figure 12 shown, the engaging portion 213A of the holding member main body portion 21A rotates in the second direction R2, which is the direction approaching the timepiece main body 110A. In this state, in a cross-sectional view, the opening portion 314A of the introduction groove 311A is not covered by the engaging portion 213A of the holding member main body portion 21A, but opens toward the back side of the timepiece 100A. In the present disclosure, the Figure 12 position of the holding member 20A shown is referred to as the loading / unloading position. Figure 12 position of the holding member 20A shown is referred to as the loading / unloading position.

[0105] Thus, in the present embodiment, the holding member main body portion 21A of the holding member 20A is configured to be movable between the fixed position and the loading / unloading position by rotating in the first direction R1 and the second direction R2.

[0106] (Method for loading / unloading the band)

[0107] Next, a method for loading / unloading the band 120 of the present embodiment will be described.

[0108] Figure 13 , Figure 14 is a cross-sectional view showing a state where the band 120 is attached to the housing 111.

[0109] First, as Figure 13 shown, in a state where the first pin 123 of the band 120 is not inserted into the introduction groove 311A, that is, in a state where the band 120 is not attached to the timepiece main body 110A, by pressing the operation portion 214A of the holding member main body portion 21A toward the second direction R2, the holding member main body portion 21A is moved to the loading / unloading position. Then, the first pin 123 is inserted from the opening portion 314A along the introduction groove 311A toward the bottom portion 315A.

[0110] Then, as Figure 14 shown, in a state where the first pin 123 is inserted until it abuts against the bottom portion 315A of the introduction groove 311A, when the pressing of the operation portion 214A of the holding member main body portion 21A is released, the holding member main body portion 21A is biased by the elastic member 22A. Then, the holding member main body portion 21A rotates in the first direction R1, as Figure 10is moved to a fixed position. Further, as described above, the opening 314A of the insertion groove 311A is covered by the engaging portion 213A of the holding member main body portion 21A, and the first pin 123 engages with the engaging portion 213A of the holding member main body portion 21A. Thus, the first pin 123 is prevented from coming out of the insertion groove 311A in a state of engaging with the engaging portion 213A of the holding member main body portion 21A, and thus the band 120 is attached to the watch main body 110A.

[0111] On the other hand, when detaching the band 120 from the watch main body 110A, the wearer presses the operation portion 214A of the holding member main body portion 21A from the Figure 10 state shown, causing the holding member main body portion 21A to rotate in the second direction R2. As a result, as Figure 13 shown, the holding member main body portion 21A moves to the attachment / detachment position, and thus the first pin 123 can be moved along the insertion groove 311A and pulled out from the opening 314A.

[0112] Thus, in the present embodiment, similar to the first embodiment described above, the holding member 20A for holding the band 120 is supported by the adapter member 30A attached to the housing 111. Therefore, it is only necessary to provide the first pin 123 extending in the width direction at the end of the band 120. That is, since the member connecting the band 120 to the watch main body 110A is attached to the housing 111, the member disposed at the end of the band 120 can be miniaturized, and the number of components can be reduced.

[0113] In addition, in the present embodiment, the adapter member 30A has a spring rod 32A that supports the holding member 20A so as to be rotatable. Therefore, the holding member 20A can be supported so as to be rotatable between the fixed position and the attachment / detachment position.

[0114] In addition, in the present embodiment, similar to the first embodiment described above, the contact surface 211A of the holding member main body portion 21A is inclined with respect to the insertion direction of the first pin 123, that is, the direction in which the insertion groove 311A opens. Therefore, even if the holding member main body portion 21A is not pressed, the first pin 123 can be inserted into the insertion groove 311A to attach the band 120 to the watch main body 110A.

[0115] (Function and Effect of the Second Embodiment)

[0116] According to such a second embodiment, the following effects can be obtained.

[0117] In the present embodiment, the adapter member 30A has a spring rod 32A that supports the holding member 20A so as to be rotatable. Therefore, the holding member 20A can be supported so as to be rotatable between the fixed position and the attachment / detachment position.

[0118] In the present embodiment, the adapter member 30A is attached to the housing 111 via the spring rod 32A, so that the adapter member 30A can be easily fixed relative to the housing 111.

[0119] In the present embodiment, the spring rod 32A supports the holding member 20A so as to be rotatable and fixes the adapter member 30A to the housing 111, thus reducing the number of components.

[0120] (Modification example)

[0121] In addition, the present disclosure is not limited to the above-described embodiments, and modifications, improvements, etc. within the scope that can achieve the object of the present disclosure are included in the present disclosure.

[0122] Figure 15 It is a schematic cross-sectional view showing the main part of the belt holding mechanism 1B of the modification example. Figure 16 It is a rear view showing the main part of the timepiece 100B of the modification example.

[0123] As Figure 15 , Figure 16 shown, the belt holding device 10B constituting the belt holding mechanism 1B of the modification example includes a holding member 20B and an adapter member 30B. Further, the adapter member 30B includes an adapter member main body portion 31B. Similar to the second embodiment described above, an engaging portion 213B and an operating portion 214B are provided on the holding member 20B. Further, a cover portion 215B that covers the back surface side of the adapter member main body portion 31B facing the timepiece main body 110B is provided on the adapter member main body portion 31B of the modification example. Thus, since the back surface side of the adapter member main body portion 31B is covered by the cover portion, it is possible to suppress the exposure of a part of the first pin 123 or the like, and the appearance can be improved.

[0124] Figure 17 It is a schematic perspective view showing the main part of the timepiece 100C of another modification example.

[0125] In the above-described first and second embodiments, the belt 120 has a belt main body 122 formed by combining a plurality of metal links 121, but is not limited thereto. For example, as Figure 17 shown, the belt main body 122C may be formed of leather, cloth, synthetic resin, or the like.

[0126] Figure 18 It is a schematic exploded perspective view showing the main part of the belt holding mechanism 1D of still another modification example.

[0127] As Figure 18As shown, the belt holding device 10D of the belt holding mechanism 1D of the clock 100D constituting the modified example includes a holding member 20D and an adapter member 30D. Further, the adapter member main body portion 31D of the adapter member 30D is integrally provided with the housing 111 of the clock main body 110D. Thereby, a spring rod or the like for attaching the adapter member main body portion 31D to the housing 111 is not required, and thus the number of components can be reduced.

[0128] In the above-described second embodiment, the spring rod 32A serves both as the second pin for supporting the holding member 20A and as the third pin for fixing the adapter member 30A to the housing 111, but the present invention is not limited thereto. For example, a second pin for supporting the holding member and a third pin for fixing the adapter member to the housing may be provided separately.

[0129] In the above-described embodiments, the first pin 123 has a cylindrical shape. However, the present invention is not limited thereto. For example, the first pin may have an elliptical cylindrical shape or a polygonal prism shape. By configuring in this way, the mounting angle of the belt with respect to the adapter member can be arbitrarily set.

[0130] In addition, the case where the first pin has a cylindrical shape or a polygonal cylindrical shape is also included in the present disclosure.

[0131] In the above-described embodiments, the clocks 100, 100A, 100B, 100C, and 100D are exemplified as wrist-worn devices, but the present invention is not limited thereto. For example, the present disclosure can be applied to wrist-worn devices such as a pulse meter and a belt attached to the wrist-worn device. Moreover, as the clocks 100, 100A, 100B, 100C, and 100D which are wrist-worn devices, whether they are so-called digital clocks, analog clocks, etc., can be applied to clocks that are worn on the wearer's wrist using a belt.

[0132] (Summary of the present disclosure)

[0133] The belt holding mechanism of the present disclosure is characterized by including: a belt having a first pin extending in the width direction at a fitting side end portion that fits with a housing; a holding member that holds the belt by fitting with the first pin; and an adapter member that supports the holding member and is attached to the housing or integrally provided with the housing.

[0134] Thereby, the holding member that holds the belt by fitting with the first pin is supported by the adapter member that is attached to the housing or integrally provided with the housing, and thus it is only necessary to provide the first pin extending in the width direction at the end portion of the belt. Therefore, the components disposed at the end portion of the belt can be miniaturized, and the number of components can be reduced.

[0135] In the belt holding mechanism of the present disclosure, it is also possible that the adapter member has a guiding groove into which the first pin can be inserted, and the first pin fits with the holding member by being inserted into the guiding groove.

[0136] Thus, by inserting the first pin into the insertion groove provided in the adapter member, the first pin can be engaged with the holding member, and thus the tape can be easily mounted relative to the housing.

[0137] In the tape holding mechanism of the present disclosure, the adapter member may support the holding member so as to be movable between a fixed position where the first pin is fixed to the insertion groove and a loading / unloading position where the first pin inserted into the insertion groove can be removed.

[0138] Thus, by moving the holding member between the fixed position and the loading / unloading position, the first pin can be engaged with the holding member, or the first pin can be removed from the insertion groove, and thus the tape can be easily loaded and unloaded relative to the housing.

[0139] In the tape holding mechanism of the present disclosure, the holding member may have a contact surface that contacts the first pin inserted into the insertion groove from the opening of the insertion groove, and the contact surface is inclined with respect to the insertion direction of the first pin so that when the first pin further inserts into the insertion groove in a state where the first pin contacts the contact surface, the holding member moves toward the loading / unloading position.

[0140] Thus, since the contact surface of the holding member is inclined with respect to the insertion direction of the first pin, the first pin can be inserted into the insertion groove and engaged with the holding member without operating the holding member. Therefore, the mounting operation of the tape can be easily performed.

[0141] In the tape holding mechanism of the present disclosure, the adapter member may also have a second pin that supports the holding member so as to be rotatable.

[0142] Thus, the adapter member can support the holding member so as to be rotatable between a fixed position and a loading / unloading position.

[0143] In the tape holding mechanism of the present disclosure, the adapter member may have a third pin for mounting to the housing.

[0144] Thus, the adapter member can be easily fixed to the housing.

[0145] In the tape holding mechanism of the present disclosure, the adapter member may also have a spring rod that constitutes the second pin and the third pin.

[0146] Thus, since the spring rod also serves as the second pin that supports the holding member so as to be rotatable and the third pin that fixes the adapter member to the housing, the number of components can be reduced.

[0147] The wrist-worn device of the present disclosure is characterized by including: a housing; a band having a first pin extending in the width direction at a fitting-side end portion that fits with the housing; a holding member that holds the band by fitting with the first pin; and an adapter member that supports the holding member and is mounted on the housing or integrally provided with the housing.

[0148] The main body portion of the wrist-worn device of the present disclosure is characterized by including: a housing; a holding member that holds the band by fitting with a first pin provided on the band; and an adapter member that supports the holding member and is mounted on the housing or integrally provided with the housing.

[0149] The band holding device of the present disclosure is characterized by including: a holding member that holds the band by fitting with a first pin provided on the band; and an adapter member that supports the holding member and is mounted on a housing or integrally provided with the housing.

[0150] The band of the present disclosure is characterized in that the band has a first pin extending in the width direction at a fitting-side end portion that fits with the housing, and the band is connected to the housing through a holding member and an adapter member, the holding member fitting with the first pin, and the adapter member supporting the holding member and being mounted on the housing or integrally provided with the housing.
