Description

[Technical field]

[0001] The present invention relates to a band and a watch. [Background technology]

[0002] Conventionally, a band that can be attached to a wristwatch or the like has a structure that includes a parent band (referred to as the "first band" in Patent Document 1) with a keeper ring attached and a tip band (referred to as the "second band" in Patent Document 1), and when the parent band (first band) and the tip band (second band) are connected, the tip of the tip band (second band) is engaged by passing the tip of the tip band (second band) through the keeper ring.

[0003] The keeper ring is designed to move freely along the band. Therefore, even if the tip of the tip band (second band) is passed through the keeper ring, if the keeper ring moves (shifts) toward the tip of the tip band (second band), there is a risk that the tip band (second band) will unintentionally come off the keeper ring.

[0004] In this regard, for example, Patent Document 1 describes providing an inclined hook part that is thicker than the band at the tip of the tip band (second band). As a result, after the hook part passes through the idle ring, the thick part of the hook part gets caught in the narrow part of the tapered inner surface of the idle ring, so that the hook part does not easily come off the idle ring.

[0005] [Patent Document 1] Japanese Utility Model Application Publication No. 63-178507 Summary of the Invention [Problem to be solved by the invention]

[0006] However, if the tip band (second band) has a thicker portion such as a hook, it is necessary to forcefully push the tip band (second band) through the keeper ring, which may cause the inner surface of the keeper ring to rub against the band, damaging the parts that make up the band's exterior.

[0007] The present invention has been made in consideration of the above circumstances, and has as its object to provide a band and a watch that can restrict the free movement of a free ring without damaging the external appearance of the band. [Means for solving the problem]

[0008] In order to solve the above problems, the band according to the present invention comprises: A first band including a band body with a free loop inserted therethrough and one end of which is attached to the case; A second band having one end attached to the case and a portion of the second band inserted into the free ring when the second band is attached to the case; Including, The first band is A protrusion protruding from a reference surface is provided on a surface of the band body that contacts an object when the band body is worn, In a side view of the band body, the protrusion is characterized in that the rise angle from the reference plane of the rising portion on the one end side is gentler than the rise angle from the reference plane of the rising portion on the other end side. Effect of the Invention

[0009] According to the present invention, it is possible to restrict the free movement of the free ring without damaging the outer surface of the band. [Brief description of the drawings]

[0011] An embodiment of a band and a watch according to the present invention will be described with reference to Figs. 1 to 8. In the following embodiment, the band is provided on a wristwatch (hereinafter, referred to as "watch 100") that is worn on the wrist. Although the following embodiment includes various technically preferable limitations for implementing the present invention, the scope of the present invention is not limited to the following embodiment and illustrated examples.

[0012] 〔composition〕 Fig. 1 is a schematic plan view of a watch equipped with a band according to this embodiment. In the following, the front surface of the band 2 shown in Fig. 1 will be referred to as the "front surface" of the band 2, and the back surface not shown in Fig. 1 will be referred to as the "back surface" of the band 2. The extension direction of the band 2 will be referred to as the longitudinal direction of the band 2 ("longitudinal direction L" in Fig. 1), and the short side direction of the band 2 perpendicular to the longitudinal direction L will be referred to as the width direction of the band 2 ("width direction W" in Fig. 1).

[0013] As shown in FIG. 1, a watch 100 of this embodiment includes a watch body 1 and a band 2 that is connected to the case of the watch body 1 (hereinafter referred to as the "main case 10"). First, the main body case 10 constituting the watch body 100 is formed in a hollow short column shape. The material from which the main body case 10 is formed is not particularly limited, but it is formed from a hard material such as a hard synthetic resin, such as super engineering plastics such as polyarylate (PAR) or engineering plastics such as polyacetal (POM), or various metals such as titanium or stainless steel (SUS).

[0014] Although not shown, a clock module is housed in the hollow portion of the main body case 10. The clock module includes various components necessary for clock functions, such as a clock movement including an analog display mechanism for moving the hands and a digital display mechanism having a liquid crystal display unit, and a circuit section for controlling the driving of these. In addition, a display section 11 for displaying the time and various information is provided on the surface of the main body case 10. In addition, operating sections such as a crown and push buttons (not shown) are provided on the sides of the main body case 10. It should be noted that FIG. 1 is a schematic illustration of the watch body 1 and does not accurately show the specific shape, configuration, etc.

[0015] As shown in FIG. 1, band attachment portions 12 for connecting a band 2 to the main case 10 are provided on the outer side of the main case 10 at positions corresponding to the 6 o'clock and 12 o'clock sides of an analog watch. The band attachment portion 12 in the illustrated example has a shape in which lugs 121 protrude from both sides in the width direction of the main body case 10, and the attachment portion 26 of the band 2 fits between the lugs 121. Note that the shape of the band attachment portion 12 is not limited to the illustrated example. The band 2 is provided with an attachment portion 26 that matches the shape of the band attachment portion 12.

[0016] As shown in FIG. 1, the band 2 includes a parent band 21 (first band) which is a short band, and a tip band 22 (second band) which is a long band. The band 2 (at least the band body 20) of this embodiment is formed in a long strip shape from various synthetic resins such as fluororubber (a resin having rubber elasticity composed of fluororesin), urethane resin, silicone resin, etc. Note that the material forming the band body 20 is not limited to those exemplified here.

[0017] The parent band 21 (first band) is attached to the band attachment part 12 on the 12 o'clock side of an analogue timepiece. The parent band 21 has an attachment part 26 attached to the main case 10 at one end, and a buckle 23 and a fastening pin 24 at the other end. In the example shown in FIG. 1, two fastening pins 24 are provided side by side in the width direction W (see FIG. 1) of the band 2. The shapes of the buckle 23 and the fastening pin 24 are not limited to the illustrated example. Only one fastening pin 24 may be provided in approximately the center of the width direction W. In addition, a free ring 25 is inserted into the band body 20 (see FIG. 1) of the parent band 21 (first band). The free ring 25 is an annular member made of the same resin material as the band body 20. The free ring 25 is movable along the longitudinal direction L of the band 2.

[0018] Furthermore, in the parent band 21 (first band) of this embodiment, a plurality of protrusions 3 protruding from a reference surface 20a (described later) are formed on the surface of the band body 20 that contacts the object to be worn (the "rear surface" of the band 2) (see FIG. 2, etc.). In this embodiment, the object to be worn by the band 2 is a human arm. If the surface that comes into contact with the arm is flat, band 2 will stick to the arm when you sweat, which is uncomfortable.

[0019] For this reason, it is preferable to provide a sweat-relief structure, such as an uneven surface, on the "back side" of the band 2 (particularly the band body 20). By providing a sweat-relief structure, it is possible to prevent the band 2 from sticking to the wearer and prevent sweat from becoming stuffy, thereby achieving a comfortable fit. In this embodiment, the protrusion 3 functions as a sweat escape structure in the band body 20 .

[0020] The range in which the protrusions 3 are provided is not limited to the example shown in Fig. 2 etc., but it is preferable that the protrusions 3 are arranged in a row over almost the entire length from one end side to the other end side of the longitudinal direction L of the band body 20. In the example shown in Fig. 2, the protrusions 3 are provided at approximately equal intervals. Also, from the standpoint of effectively allowing sweat to escape and preventing stuffiness, it is preferable that the protrusions 3 be located at least at both ends of the band body 20 in the width direction W.

[0021] The tip band 22 (second band) is attached to the band attachment portion 12 on the 6 o'clock side of an analog timepiece. The tip band 22 has an attachment portion 26 that is attached to the main case 10 on one end side. The tip band 22 (second band) has small holes 221 into which the joining bars 24 are inserted formed in a row along the longitudinal direction L. In this embodiment, the small holes 221 of the tip band 22 are also formed in a row in the width direction W of the band 2, two by two, corresponding to the joining bars 24 arranged side by side in the width direction W as shown in Fig. 1. In the case where there is only one joining bar 24, the small holes 221 may also be arranged in a row, for example in the center of the width direction W, corresponding to the positions of the joining bars 24.

[0022] When the band 2 of this embodiment is worn, the other end (free end) of the pointed end band 22 (second band) is inserted into the buckle 23 provided on the other end of the parent band 21 (first band). The parent band 21 (first band) and the pointed end band 22 (second band) are then connected by engaging the buckle pin 24 of the buckle 23 with one of the small holes 221. In this state, the other end of the pointed end band 22 (second band) overlapping the front side of the parent band 21 (first band) is inserted into the free ring 25 (see FIG. 6).

[0023] The thickness of the arms of users on whom the band 2 is to be worn varies. The tip band 22 (second band) is formed to be longer so that the band 2 can be worn on thick arms as well. For this reason, when the band 2 is worn on a thin arm, for example, the free end side (the other end side not connected to the main body case 10) of the tip band 22 (second band) may be left largely surplus. In this regard, by inserting the other end side of the tip band 22 into the free ring 25, it is possible to prevent the surplus part of the tip band 22 from jumping up and interfering with wearing the band or from getting caught on the cuffs of clothing, etc.

[0024] FIG. 2 is a plan view of the parent band (first band) as viewed from the back side of the band, and FIG. 3 is an enlarged view of an area III enclosed by a dashed line in FIG. 4 is a side view of the parent band (first band), and FIG. 5 is an enlarged view of a V portion enclosed by a dashed line in FIG. Fig. 6 is a side view of the main part of the band in a state where the parent band (first band) and the tip band (second band) are connected. In Fig. 6, the thick arrow indicates the direction in which the tip band 22 (second band) is inserted into the buckle 23 of the parent band 21 (first band) when the band is attached. 2 to 6, "D1" is the direction in which the idler ring 25 faces the buckle 23, and "D2" is the direction in which the idler ring 25 faces the attachment portion 26 of the parent band 21 (first band). In Fig. 2 to 6, the "D1" direction and the "D2" direction are each indicated by an outlined arrow.

[0025] As shown in Fig. 6, the free end side of the tip band 22 (second band) inserted into the buckle 23 is inserted into the free ring 25 in the "D2" direction. If the free ring 25 moves in the "D2" direction beyond the free end of the tip band 22 (second band), the free ring 25 will no longer be able to hold the tip band 22 (second band). Conversely, when the free ring 25 moves in the "D1" direction, the free ring 25 does not come off the tip band 22 (second band) and can hold down the free end side of the tip band 22 (second band).

[0026] For this reason, in band 2 of this embodiment, by devising the shape of protrusion 3 that functions as a sweat escape structure as described above, it is configured so that loose ring 25 provided on parent band 21 (first band) moves easily in the "D1" direction and does not move easily in the "D2" direction. In other words, when watch 100 is worn on the wrist, loose ring 25 moves easily, but while watch 100 is worn on the wrist, loose ring 25 does not move easily. A specific configuration will be described below.

[0027] 4 and 5, in a side view of the band body 20, the rise angle of the rising portion 31 at one end side (attachment portion 26 side) of the parent band 21 (first band) from the reference surface 20a is gentler than the rise angle of the rising portion 32 at the other end side (buckle 23 side) from the reference surface 20a. In the example shown in Figs. 2 and 4, the protrusion 3 provided on the side of the parent band 21 (first band) closest to the buckle 23 has only the rising portion 31 at one end side, and the other end side is integrated with the band body 20.

[0028] Here, reference surface 20a refers to the flat surface of the "back side" of band 2. For example, even if part of the "back side" of band 2 is dug out to have a thin portion or conversely, has a thick portion, the surface on which protrusion 3 is formed is taken as reference surface 20a, and the rising angles of rising portions 31, 32 are compared in terms of the angle from reference surface 20a.

[0029] There is no particular limitation on the method for making the rise angle from the reference surface 20a of the rising portion 31 on one end side gentler than the rise angle from the reference surface 20a of the rising portion 32 on the other end side. For example, a rounded portion having the smallest possible radius of curvature ("R2" in Figures 3 and 5) is formed at the upper portion of the raised portion 32 on the other end side of the protrusion 3, while a rounded portion having a larger radius of curvature ("R1" in Figures 3 and 5) is formed at the upper portion of the raised portion 31 on one end side of the protrusion 3 than the rounded portion R2 formed at the upper portion of the raised portion 32 on the other end side.

[0030] As described above, when the band 2 is made of synthetic resin, the corners are not made perfectly right angles but are made somewhat rounded in order to facilitate removal from the mold during molding. The rounded portion R2 of the rising portion 32 on the other end side being a "rounded portion with the minimum radius of curvature that can be processed" means that the rounded portion R2 has the minimum degree of roundness required for such processing. Since the radius of curvature of the rounded portion R2 is small and the rising portion 32 on the other end side rises steeply from the reference surface 20a, the free ring 25 gets caught more when it tries to move in the "D2" direction, making it difficult to move. In contrast, the larger the radius of curvature of rounded portion R1 of rising portion 31 on one end side, the less the free ring 25 gets caught when it moves in the "D1" direction, and the easier it is for the free ring 25 to move smoothly.

[0031] Furthermore, in order to make the rising portion 31 on one end side rise more gently, the rising portion 31 on one end side of the protrusion 3 may be subjected to C-face processing. It is sufficient that the rising portion 31 on one end side (the mounting portion 26 side) of the protrusion 3 is gentler than the rising portion 32 on the other end side (the buckle 23 side). The radii of curvature of the rounded portions R1, R2, and, if C-face processing is applied to the rising portion 31 on the one end side, the extent of the C-face to be provided, are set appropriately.

[0032] [Effect] Next, the operation of the band 2 and the watch 100 equipped with the band 2 of this embodiment will be described. When attaching the band 2 to the watch body 1, the attachment portion 26 of the band 2 is fitted into the band attachment portion 12 of the main body case 10 of the watch body 1, and a spring bar or the like is inserted into the fitted portion. This causes the band 2 to be locked onto the main body case 10.

[0033] When attaching the band 2 to an object such as the arm, the free end of the pointed band 22 (second band) is inserted into the buckle 23 of the main band 21 (first band), and the buckle 24 is inserted into the small hole 221 at a position that matches the thickness of the arm to lock it into the main band 21 (first band), as shown in Fig. 6. Once the main band 21 (first band) and the pointed band 22 (second band) are connected in this way, the free end of the pointed band 22 (second band) is inserted into the free ring 25 to hold the free end of the pointed band 22 (second band) so that it does not jump up.

[0034] At this time, if the free ring 25 is pushed by the tip band 22 (second band) and moves in the "D2" direction, the free end of the tip band 22 (second band) cannot be held down by the free ring 25. If the free end of the tip band 22 (second band) comes off the free ring 25, not only will the excess part of the tip band 22 bounce up and get in the way of putting it on or get caught on the cuffs of clothing, but the attachment bar 24 will also be more likely to come off the small hole 221. If the attachment bar 24 comes off the small hole 221, there is also the risk that the band 2 will come off the arm unintentionally.

[0035] In this regard, in the present embodiment, the rising portion 32 on the other end side (buckle 23 side) of the protrusion 3 rises steeply from the reference plane 20a, and the rising portion 31 on one end side (mounting portion 26 side) rises at a gentler angle than the rising portion 32 on the other end side. For this reason, the idler ring 25 is easy to move in the direction "D1", which is the direction away from the free end of the tip band 22 (second band), but is difficult to move in the direction "D2", which is the direction approaching the free end of the tip band 22 (second band), as it gets caught on the raised portion 32 of the protrusion 3.

[0036] As a result, even if the idling ring 25 is pushed slightly in the "D2" direction when threading the tip band 22 (second band), the idling ring 25 does not move in the "D2" direction, and the tip band 22 (second band) can be easily threaded through the idling ring 25. Also, even after the tip band 22 (second band) is threaded through the idling ring 25, the idling ring 25 is unlikely to move in the "D2" direction toward the free end of the tip band 22 (second band). For this reason, the idling ring 25 is unlikely to come off the tip band 22 (second band). On the other hand, the keeper ring 25 moves smoothly in the "D1" direction. For this reason, even if the excess portion on the free end side of the tip band 22 (second band) is short, such as when the band 2 is worn on a thick arm, the tip band 22 (second band) can be firmly held in place near the buckle 23.

[0037] Furthermore, because the idle ring 25 is an annular member made of the same resin material as the band body 20, it is prone to bulging or bending and floating in the center of the width direction W of the band 2. However, the protrusions 3 of this embodiment are provided at both ends of the width direction W of the band 2, as shown in Figure 2. For this reason, even if the center of the idle ring 25 bulges or bends slightly, the protrusions 3 (particularly the raised portion 32 on the other end side (buckle 23 side) of the protrusion 3) will catch on the inside surface of the idle ring 25, and the movement of the idle ring 25 in the "D2" direction can be appropriately restricted.

[0038] Furthermore, the position of the free ring 25 that holds the tip band 22 (second band) varies depending on the thickness of the arm on which the band 2 is worn. For example, when worn on a thin arm, the excess portion on the free end side of the tip band 22 (second band) is long, and in order to effectively prevent the tip band 22 (second band) from jumping up, it is preferable that the free ring 25 holds the tip band 22 (second band) relatively close to the attachment portion 26 of the parent band 21 (first band). Also, for example, when worn on a thick arm, the excess portion on the free end side of the tip band 22 (second band) is short, and the free ring 25 holds the tip band 22 (second band) relatively close to the buckle 23 of the parent band 21 (first band).

[0039] In this embodiment, the protrusion 3 is provided over almost the entirety of the band body 20 from one end side to the other end side in the longitudinal direction L. Therefore, no matter where the free ring 25 is positioned to press the tip band 22 (second band), the free ring 25 can be effectively prevented from moving (shifting) in the "D2" direction, which is the direction in which the free ring 25 comes off the tip band 22 (second band).

[0040] 7 is a plan view of the band shown in FIG. 6 as seen from the direction of an arrow VII, and FIG. 8 is a cross-sectional view of a main part of the band taken along line VIII in FIG. 6 to 8, the tip band 22 (second band) of the band 2 is disposed so that a large portion of the tip band 22 overlaps the front side of the parent band 21 (first band). The parent band 21 (first band) has a large portion that comes into contact with the arm of the wearer. For this reason, by providing a protrusion 3 on the back side of band body 20 of parent band 21 (first band), band 2 is prevented from sticking to the arm even when sweating, and sweat can be effectively released.

[0041] 6 to 8 (particularly FIG. 8), only the parent band 21 (first band) has a back side of the band body 20 in contact with the free ring 25. For this reason, it is only the parent band 21 (first band) that needs to be provided with the protrusion 3 to restrict the movement of the free ring 25 in the "D2" direction. Furthermore, even if the band 2 (parent band 21 and tip band 22) and the free ring 25 rub against each other repeatedly, it is the protruding part 3 that protrudes more than the others that is most likely to be damaged. In this regard, by providing the protruding part 3 that restricts the movement of the free ring 25 on the back side of the band body 20, even if the protruding part 3 is scratched and scraped off through repeated use, the appearance of the watch 100 is not affected and a beautiful appearance can be maintained.

[0042] 〔effect〕 As described above, the band 2 in this embodiment includes a band main body 20 through which the idler ring 25 is inserted, a parent band (first band) 21 having one end attached to the case (main body case 10), and a pointed band (second band) 22 having one end attached to the main body case 10 and a portion of which is inserted into the idler ring 25 when worn, and the parent band (first band) 21 has a protrusion 3 that protrudes from a reference surface 20a on the surface of the band main body 20 that comes into contact with the object to be worn, such as the arm, when worn (the "rear surface" of the band 2), and in a side view of the band main body 20, the rise angle of the rise portion 31 on one end side from the reference surface 20a is gentler than the rise angle of the rise portion 32 on the other end side from the reference surface 20a. As a result, when the idler ring 25 tries to move in the "D2" direction, it gets caught on the raised portion 32 on the other end side and the movement is restricted, whereas when the idler ring 25 tries to move in the "D1" direction, it can move smoothly with less getting caught. Therefore, when the position of the swivel ring 25 is moved according to the thickness of the user's arm, it can be moved and adjusted without getting caught, and once the tip band 22 (second band) is inserted into the swivel ring 25, it is possible to effectively prevent the swivel ring 25 from moving (shifting) in the direction "D2", which is the direction in which the swivel ring 25 comes off the tip band 22 (second band).

[0043] In this embodiment, the parent band (first band) 21 has a buckle 23, and the parent band (first band) 21 and the tip band (second band) 22 have attachment portions 26 that are attached to the main body case 10, and the band body 20 of the parent band (first band) 21 has a plurality of protrusions 3. When the parent band 21 and the tip band 22 are connected and the other end of the tip band 22 is inserted into the idling ring 25 during wearing, the appropriate position of the idling ring 25 changes depending on the thickness of the user's arm, such that if the arm is thick, it is positioned closer to the buckle 23, and if the arm is thin, it is positioned closer to the attachment part 26. In this regard, by providing multiple protrusions 3 as in this embodiment, the movement of the free ring 25 can be appropriately restricted regardless of the thickness of the arm on which the band 2 is worn, making it less likely to come off.

[0044] In addition, in the band 2 of this embodiment, a rounded portion R2 having the smallest radius of curvature that can be processed is formed at the upper part of the raised portion 32 on the other end side of the protrusion 3, and a rounded portion R1 having a radius of curvature larger than the radius of curvature of the rounded portion R2 formed at the upper part of the raised portion 32 on the other end side is formed at the upper part of the raised portion 31 on one end side of the protrusion 3. This makes it difficult for the free ring 25 to move in the direction "D2", which is the direction in which it would come off the tip band 22 (second band), and conversely makes it easier for the free ring 25 to move in the direction "D1", which is the direction in which it becomes difficult for the free ring 25 to come off the tip band 22 (second band). This makes it easy to adjust the position of the free ring 25 according to the thickness of the user's arm, etc.

[0045] In the band 2 of this embodiment, the rising portion 31 on one end side of the projection 3 may be subjected to C-face processing. The more gentle the rise of the rising portion 31 on one end side, the easier it is for the free ring 25 to move smoothly in the "D1" direction, and the easier it is to adjust the position of the free ring 25 according to the thickness of the user's arm, etc. In this regard, providing a C-face on the rising portion 31 on one end side is also effective in making the rise of the rising portion 31 on one end side more gentle.

[0046] In the band 2 of this embodiment, the protrusions 3 are arranged in a row over the entire length of the band body 20 in the longitudinal direction L from one end side to the other end side. As a result, when the position of the swivel ring 25 is moved along the longitudinal direction L in accordance with the thickness of the arm of the user wearing the band 2, the swivel ring 25 moves smoothly in the "D1" direction in any position, and movement in the "D2" direction can be restricted by the protrusion 3. It also allows sweat to escape effectively when you sweat.

[0047] In the band 2 of this embodiment, the protrusions 3 are disposed at least at both ends of the band body 20 in a width direction W perpendicular to the longitudinal direction L. Therefore, even if the center portion of the idle ring 25 in the width direction W swells or bends and does not easily come into close contact with the band body 20, the protrusion 3 can effectively restrict the movement of the idle ring 25.

[0048] In the band 2 of this embodiment, the protruding portion 3 also serves as a sweat escape structure in the band body 20 . This prevents the band 2 from becoming stuffy or sticking to the arm even when sweating, allowing the band 2 to be worn comfortably. In the embodiment, the function of the sweat escape structure provided to obtain a comfortable fit is given to the protrusion 3 for restricting the movement of the free ring 25. This makes it possible to improve the fit and make the free ring 25 less likely to come off without adding a separate new structure.

[0049] Furthermore, when such a band 2 is attached to the main body case 10 of the watch main body 1 to form a watch 100 (wristwatch), the movement of the free ring 25 is restricted, and it is possible to prevent the free ring 25 from unintentionally coming off the pointed band 22 (second band) and the free end side of the pointed band 22 (second band) from getting caught on the sleeve of clothing or the like and becoming an obstacle. Furthermore, it is possible to avoid the risk that the hook bar 24 will come off the small hole 221 when the pointed band 22 (second band) comes off, and the entire band 2 will come off and the watch 100 will be dropped. In addition, since the movement of the free ring 25 is restricted by the protrusion 3 provided on the back surface of the band 2, even if the protrusion 3 is scraped off or the inside of the free ring 25 is rubbed and scratched by repeatedly putting on and taking off the band 2, the appearance of the band 2 and therefore the watch 100 will not be impaired.

[0050] [Modifications] Although one embodiment of the present invention has been described above, it goes without saying that the present invention is not limited to this embodiment, and various modifications are possible as appropriate without departing from the spirit and scope of the present invention.

[0051] For example, in this embodiment, the protrusion 3 is provided only on the band body 20 of the parent band 21 (first band), but the protrusion 3 may also be provided on the back side of the band body 20 of the pointed end band 22 (second band). This allows the parent band 21 (first band) and the pointed end band 22 (second band) to have the same design, and excellent design effects can be expected.

[0052] In addition, in the present embodiment, the protrusions 3 are provided at both ends of the band 2 in the width direction W, but the arrangement and configuration of the protrusions 3 are not limited to this. For example, the protrusions 3 may be provided across the entire width direction W of the band 2, forming a striped pattern when the band body 20 is viewed from the back side. In this case as well, when viewed from the side of the band body 20, the protrusions 3 are configured such that the rise angle from the reference plane 20a of the rising portion 31 on one end side is gentler than the rise angle from the reference plane 20a of the rising portion 32 on the other end side.

[0053] In addition, in this embodiment, the idler ring 25 is an annular member formed from the same resin material as the band main body 20, but the idler ring 25 may be formed from a material other than resin, such as metal, for example. In this case, the free ring 25 does not swell, bend or deform in the center of the width direction W of the band 2. For this reason, the protrusion 3 may be provided in the center of the width direction W of the band 2, for example.

[0054] Furthermore, in this embodiment, an example has been described in which the band 2 is connected to the main case 10 of the watch 100, but the band 2 is not limited to being a watch band 2 that is attached to the main case 10 of the watch 100. For example, the band 2 of the present invention can be applied as a band that is connected to the main body case of various devices (for example, a smart watch, a pedometer, a heart rate monitor, etc.) that are fixed to the body by the band 2. Furthermore, the band 2 has a slack ring 25, and can be widely used as long as the free end side of the pointed band 22 (second band) is inserted into the slack ring 25, for example, it may be worn around a pet's neck, etc.

[0055] Although several embodiments of the present invention have been described above, the scope of the present invention is not limited to the above-described embodiments, but includes the scope of the invention described in the claims and its equivalents. [Explanation of symbols]
