Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, among shaped parts, decorative crystals and the like have large dimensional errors. Therefore, according to the structure described in Patent Document 1, it is necessary to adjust the inclination of the peripheral edge of the opening provided in the plate-like member to the inclination of the peripheral portion different for each shaped part. Further, according to the structure described in Patent Document 1, after sandwiching the shaped part between the upper and lower plate-like members, it is necessary to fix these upper and lower plate-like members using other members. Thus, mounting the shaped part on the dial or the like requires complicated work and is not easy.

[0010] Hereinafter, a clock 1 having three mounting structures 2, 4, and 6 with shaped parts 12 according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view of the clock 1. The clock 1 is, for example, a mechanical clock. FIG. 1 shows a state where the mechanical operation is not performed.

[0011] The mechanical operation refers to an operation such as the rotation of the dial 3 and the decoration device 16 described later when a predetermined time is reached. Further, a melody may flow. FIG. 2 is a perspective view of the internal structure of the clock 1.

[0012] As shown in FIG. 1, the clock 1 has a substantially elliptical housing 10 with the vertical direction as the long side when viewed from the front. Inside the housing 10, a clock device 14 and a decoration device 16 are arranged vertically.

[0013] As shown in FIGS. 1 and 2, the clock device 14 is installed at the center in the left-right direction of the housing 10 and in a region approximately two-thirds from the top. The clock device 14 has a dial 3, a pointer portion 18, and a rotating plate 40.

[0014] On the dial 3, the numbers from "1" to "12" representing the time are marked. Hereinafter, the 12 o'clock direction indicated by the dial 3 will be described as up, the 6 o'clock direction as down, the 3 o'clock direction as right, and the 9 o'clock direction as left. Also, the front of the clock 1 will be described as the front and the back as the rear. Note that the vertical direction, the horizontal direction, and the front-rear direction are orthogonal to each other.

[0015] The dial plate 3 has an annular shape when viewed from the front. The dial plate 3 includes a first dial plate 31, a second dial plate 32, a third dial plate 33, a fourth dial plate 34, a fifth dial plate 35, and a sixth dial plate 36.

[0016] On the dial plate 3, in a clockwise direction, the first dial plate 31, the second dial plate 32, the third dial plate 33, the fourth dial plate 34, the fifth dial plate 35, and the sixth dial plate 36 are arranged in this order, forming an annulus. Each dial plate 3 is provided rotatably with respect to a rotating plate 40 described later.

[0017] The number "12" is marked on the first dial plate 31. The number "4" is marked on the third dial plate 33. The number "8" is marked on the fifth dial plate 35.

[0018] The numbers "1", "2", and "3" are marked on the second dial plate 32. The numbers "5", "6", and "7" are marked on the fourth dial plate 34. The numbers "9", "10", and "11" are marked on the sixth dial plate 36.

[0019] The first dial plate 31, the third dial plate 33, and the fifth dial plate 35 are on the same plane. The second dial plate 32, the fourth dial plate 34, and the sixth dial plate 36 are on the same plane. The second dial plate 32, the fourth dial plate 34, and the sixth dial plate 36 are located in front of the first dial plate 31, the third dial plate 33, and the fifth dial plate 35.

[0020] FIG. 3 is a front perspective view of the second dial plate 32. FIG. 4 is a front view of the mounting structure 2. FIG. 5 is a rear perspective view of the second dial plate 32. FIG. 6 is a rear view of the mounting structure 2.

[0021] As shown in FIGS. 3 to 6, the second dial plate 32 is a plate-like member having a front main surface 321 and a rear main surface 322. The second dial plate 32 includes an annular plate 32a, a mounting structure 2, a left connecting plate 32b, a right connecting plate 32c, and a joining shaft 32d.

[0022] The annular plate 32a has a substantially fan-shaped annular shape. More specifically, the annular plate 32a is an area surrounded by two concentric circles centered on the central axis Ax of the dial plate 3 and two straight lines extending in the radial direction.

[0023] When viewed from the front, the mounting structure 2 has a substantially bell-shaped outer edge 21. Specifically, the lower part of the mounting structure 2 is connected by an arc where the left lower end and the right lower end of the mounting structure 2 protrude downward. The lower center of the mounting structure 2 has a downwardly protruding semi-circular shape. The diameter of the semi-circular shape is approximately one-third of the length of the arc connecting the left lower end and the right lower end.

[0024] The upper part of the mounting structure 2 has a substantially upwardly protruding semi-circular shape. The diameter of the substantially upwardly protruding semi-circular shape is shorter than the length of the arc connecting the left lower end and the right lower end. The upper part of the mounting structure 2 and the left and right lower ends are connected by a smooth curve.

[0025] The mounting structure 2 is located at the center of an isosceles triangle with the left connecting plate 32b and the right connecting plate 32c as the equal sides. More specifically, the mounting structure 2 is provided below the annular plate 32a. The upper end of the mounting structure 2 is connected to the center of the left and right lower ends of the annular plate 32a in the left-right direction.

[0026] When viewed from the front, the left connecting plate 32b extends linearly from the lower left part of the annular plate 32a in the lower right direction. When viewed from the front, the right connecting plate 32c extends linearly from the lower right part of the annular plate 32a in the lower left direction. The lower end of the left connecting plate 32b is connected to the left part of the mounting structure 2. The lower end of the right connecting plate 32c is connected to the right part of the mounting structure 2.

[0027] As shown in FIGS. 5 and 6, the joining shaft 32d protrudes rearward from the lower center of the rear main surface 322 of the second dial plate 32. The central axis of the joining shaft 32d is parallel to the central axis Ax (see FIG. 2).

[0028] As shown in FIG. 2, the rotating plate 40 has a substantially disk shape and is provided rotatably around the pointer shaft 18a. The rotating plate 40 has a front main surface 401 and a rear main surface 402 centered on the central axis Ax.

[0029] The rotating plate 40 is provided with a second character plate 32. The second character plate 32 is provided on the rotating plate 40 such that the front main surface 401 of the rotating plate 40 faces the rear main surface 322 of the second character plate 32. The second character plate 32 is provided on the rotating plate 40 such that the outer circumference of the rotating plate 40 and the outer edge on the arc of the second character plate 32 overlap when viewed from the front.

[0030] The joint shaft 32d is joined to a gear shaft (not shown) of the rotating plate 40. During the mechanism operation, the second character plate 32 rotates with respect to the rotating plate 40 about the joint shaft 32d. During the mechanism operation, the second character plate 32 rotates with the rotating plate 40 about the central axis Ax with respect to the housing 10. These two rotations may be performed simultaneously or at different timings.

[0031] As shown in FIG. 2, the fourth character plate 34 includes an annular plate 34a, a mounting structure 4, a left connecting plate 34b, a right connecting plate 34c, and a joint shaft (not shown). The fourth character plate 34 is formed in the same manner as the second character plate 32. However, the mounting structure 4 is provided on the annular plate 34a with the vertical direction opposite to that of the mounting structure 2.

[0032] The sixth character plate 36 includes an annular plate 36a, a mounting structure 6, a left connecting plate 36b, a right connecting plate 36c, and a joint shaft (not shown). The sixth character plate 36 is formed in the same manner as the second character plate 32.

[0033] On the rotating plate 40, the fourth character plate 34 and the sixth character plate 36 are provided in the same manner as the second character plate 32.

[0034] The fourth character plate 34 rotates with respect to the rotating plate 40 about a joint shaft (not shown) during the mechanism operation in the same manner as the second character plate 32. During the mechanism operation, the fourth character plate 34 rotates with the rotating plate 40 about the central axis Ax with respect to the housing 10. These two rotations may be performed simultaneously or at different timings.

[0035] Similar to the second dial plate 32, the sixth dial plate 36 rotates with respect to the rotating plate 40 about a joint axis (not shown) during the mechanism operation. During the mechanism operation, the sixth dial plate 36 rotates with respect to the housing 10 together with the rotating plate 40 about the central axis line Ax. These two rotations may be performed simultaneously or at different timings.

[0036] The first dial plate 31, the third dial plate 33, and the fifth dial plate 35 are different from the second dial plate 32, the fourth dial plate 34, and the sixth dial plate 36 in that they do not have the mounting structures 2, 4, 6. Connecting pins 42 are provided on the first dial plate 31, the third dial plate 33, and the fifth dial plate 35 instead of the mounting structures 2, 4, 6.

[0037] The pointer part 18 shown in FIG. 1 includes a pointer shaft 18a (see FIG. 2), an hour hand 18t, a minute hand 18m, and a second hand 18s. The hour hand 18t, the minute hand 18m, and the second hand 18s display the time.

[0038] The pointer shaft 18a protrudes forward along the central axis line Ax. One ends of the hour hand 18t, the minute hand 18m, and the second hand 18s are attached to the pointer shaft 18a. When viewed from the front, the other end of the hour hand 18t points to the time on the dial plate 3, and the other ends of the minute hand 18m and the second hand 18s overlap the dial plate 3. The pointer shaft 18a rotates about the central axis line Ax with respect to the dial plate 3.

[0039] Decorations such as jewels are attached to the decoration device 16. It is installed below the timepiece device 14 at the center in the left - right direction of the housing 10. During the mechanism operation, it rotates with respect to the housing 10 about the vertical axis line.

[0040] Next, the details of the mounting structure 2 will be described with reference to the drawings. FIG. 3 is a front perspective view of the second dial plate 32. FIG. 4 is a front view of the mounting structure 2. FIG. 5 is a rear perspective view of the second dial plate 32. FIG. 6 is a rear view of the mounting structure 2.

[0041] As shown in FIGS. 3 to 6, the mounting structure 2 includes an outer edge 21, an opening 22 located inside the outer edge 21, a pair of pressing arms 23 (first pressing portions) located above the opening 22, a pair of supports 24 (second supporting portions) located above and below the opening 22, and a pair of pressing plates 25 (second pressing portions) located on the rear side of the opening 22.

[0042] The mounting structure 2 is a plate-shaped member. The outer edge 21, the opening 22, a pair of pressing arms 23 formed in an arm shape, a pair of supports 24, and a pair of pressing plates 25 formed in a plate shape are integrally formed.

[0043] The mounting structure 2 can mount the shaped part 12. The shaped part 12 is mounted and held in the opening 22. Mounting means that the shaped part 12 inserted into the opening 22 is fixed in the vertical, horizontal, and front-rear directions.

[0044] As shown in FIGS. 3 to 6, the shaped part 12 is flat and extends in the vertical and horizontal directions. Specifically, the shaped part 12 has a regular octagonal prism part 121, a first regular octagonal pyramid part 122, and a second regular octagonal pyramid part 123. In other words, the shaped part 12 is formed by diamond cutting.

[0045] More specifically, the regular octagonal prism part 121 has a regular octagonal prism shape that slightly extends in the front-rear direction. The regular octagonal prism part 121 has eight side surfaces 121a that extend in the front-rear direction. The first regular octagonal pyramid part 122 is in the shape of a regular octagonal pyramid with its apex slightly protruding forward from the front surface of the regular octagonal prism part 121. The second regular octagonal pyramid part 123 is in the shape of a regular octagonal pyramid with its apex slightly protruding backward from the rear surface of the regular octagonal prism part 121.

[0046] The first regular octagonal pyramid part 122 protrudes forward from the regular octagonal prism part 121. The second regular octagonal pyramid part 123 protrudes backward from the regular octagonal prism part 121. Each ridge line of the first regular octagonal pyramid part 122 and the second regular octagonal pyramid part 123 is connected to each ridge line of the regular octagonal prism part 121.

[0047] The regular octagonal column portion 121 may be, for example, a regular decagonal column portion. At this time, the first regular octagonal pyramid portion 122 and the second regular octagonal pyramid portion 123 are decagonal pyramid portions.

[0048] An inner edge 221 is provided on the outer periphery of the opening of the opening portion 22. The shaped part 12 is surrounded by the inner edge 221 and penetrates the mounting structure 2 in the front-rear direction. Specifically, the opening portion 22 is an opening provided inside the outer edge 21, and is substantially regular octagonal in shape when viewed from the front.

[0049] As shown in FIG. 6, the lower part of the shaped part 12 inserted into the opening portion 22 is in contact with the inner edge 221 of the opening portion 22. More specifically, the inner edge 221 of the opening portion 22 is in contact with the side surface 121a8 located at the lower left end and the side surface 121a7 located at the lower right end of the shaped part 12.

[0050] As shown in FIGS. 3 and 4, the first pressing arm 231 and the second pressing arm 232 that constitute a pair of pressing arms 23 are provided symmetrically with respect to the central axis in the left-right direction of the opening portion 22. The first pressing arm 231 and the second pressing arm 232 are formed to be elastically deformable, and expand downward in a front view when the shaped part 12 is inserted.

[0051] More specifically, the first pressing arm 231 has a straight portion 231a extending vertically from the inner edge 221 and an inclined portion 231b extending obliquely downward to the lower right from the straight portion 231a. The acute angle formed by the inclined portion 231b and the vertical axis is approximately 45 degrees. The upper end of the straight portion 231a is connected to the upper right part of the opening portion 22. The lower end of the straight portion 231a is connected to the upper end of the inclined portion 231b.

[0052] The first pressing arm 231 is in contact with the upper part of the shaped part 12 inserted into the opening portion 22. More specifically, a bulging portion 231bt that bulges is formed at the tip portion of the inclined portion 231b, and this bulging portion 231bt is in contact with the side surface 121a5 (see FIG. 4) located at the upper right end of the regular octagonal column portion 121 provided in the shaped part 12.

[0053] The second pressing arm 232 is formed symmetrically with the first pressing arm 231 and has a straight portion 232a and an inclined portion 232b. In the second pressing arm 232, a bulging portion 232bt at the tip of the inclined portion 232b is in contact with a side surface 121a6 located at the upper left end of the regular octagonal prism portion 121 in the shaped part 12.

[0054] As shown in FIGS. 3 to 6, a set of supports 24 includes a first support 241 and a second support 242. The first support 241 and the second support 242 are provided facing each other vertically.

[0055] The first support 241 is located between the first pressing arm 231 and the second pressing arm 232 when viewed from the front. The first support 241 is located above the shaped part 12 inserted into the opening 22. The lower end of the first support 241 is located above the center of the shaped part 12.

[0056] The first support 241 includes a main body 241b and a first support head 241h. As shown in FIGS. 3 and 4, the main body 241b is a plate-like member extending downward (i.e., inside the opening 22) from the center of the upper end of the opening 22 where the inner edge 221 is interrupted when viewed from the front. The first support head 241h protrudes downward from the front lower end of the main body 241b.

[0057] More specifically, the first support head 241h is substantially semi-elliptical with the vertical direction as the major axis, and the arc of the substantially semi-elliptical shape is located downward. The first support head 241h has a front main surface 241ha and a rear main surface 241hb.

[0058] As shown in FIG. 7, the first support head 241h is located in front of the first regular octagonal pyramid portion 122 of the shaped part 12. A contact protrusion 241j is formed at the tip of the rear main surface 241hb of the first support head 241h. As shown in FIG. 8(b), the contact protrusion 241j is formed in a substantially V-shaped concave shape inclined in the front-rear direction. The contact protrusion 241j is arc-shaped following the tip shape of the first support head 241h. The contact protrusion 241j is in contact with the front portion of the first regular octagonal pyramid portion 122.

[0059] As shown in FIG. 6, the protrusion 241c (first protrusion) of the main body 241b has a slight gap with the side surface 121a1 located at the upper end of the regular octagonal column portion 121 (see also FIG. 7). This gap varies according to the dimensional error of the shaped part 12.

[0060] As shown in FIGS. 3 and 4, the second support 242 is a plate-like member that extends upward (i.e., inside the opening 22) from the center of the lower end of the opening 22 where the inner edge 221 is interrupted between a pair of support portions 221a (to be described later) when viewed from the front.

[0061] More specifically, the length of the second support 242 in the left-right direction is substantially equal to the length of the first support 241 in the left-right direction. The second support 242 is located below the shaped part 12 inserted into the opening 22. The upper end of the second support 242 is located below the center of the shaped part 12.

[0062] As shown in FIGS. 3 and 4, a second support head 242h that is substantially semicircular and has a substantially semicircular arc located upward is provided at the front upper part of the second support 242 when viewed from the front. The second support head 242h has a front main surface 242ha and a rear main surface 242hb.

[0063] The second support head 242h is located in front of the first regular octagonal pyramid portion 122 of the shaped part 12. The rear main surface 242hb is in contact with the lower part of the first regular octagonal pyramid portion 122. As shown in FIG. 7, the second support head 242h can cover the through hole 12a used during injection molding formed in the shaped part 12. Also, as shown in FIG. 8(b), the rear main surface 242hb is formed in a substantially V-shaped concave shape that is inclined in the front-rear direction. Therefore, the rear main surface 242hb is in contact along the ridge line of the first regular octagonal pyramid portion 122.

[0064] As shown in FIG. 7, the protrusion 242a (second protrusion) on the rear main surface 242hb of the second support 242 has a slight gap with the side surface 121a2 located at the lower end of the regular octagonal column portion 121. This gap changes according to the dimensional error of the shaped part 12.

[0065] As shown in FIGS. 5 and 6, a set of pressing plates 25 includes a first pressing plate 251 and a second pressing plate 252. The first pressing plate 251 and the second pressing plate 252 are line-symmetric with respect to the vertical axis passing through the center of the shaped part 12 inserted into the opening 22.

[0066] When viewed from the rear, the first pressing plate 251 and the second pressing plate 252 are plate-like members extending from left to right and from right to left of the opening 22, respectively. The first pressing plate 251 and the second pressing plate 252 each have a front main surface 251a, 252a and a rear main surface 251b, 252b.

[0067] More specifically, the vertical lengths of the first pressing plate 251 and the second pressing plate 252 are substantially equal to the left-right length of the first support 241, and are formed in a plate shape so as to be elastically deformable like a leaf spring. The tips of the first pressing plate 251 and the second pressing plate 252 are separated. The base ends of the first pressing plate 251 and the second pressing plate 252 are connected to the outside of the opening 22.

[0068] The first pressing plate 251 and the second pressing plate 252 are located behind the second regular octagonal pyramid portion 123 of the shaped part 12. As shown in Fig. 8(a), on the rear main surfaces 251b and 252b, first contact convex portions 251j1, 251j2 and second contact convex portions 252j1, 252j2 are provided at the tip side and the base end side respectively. The widths of the first contact convex portions 251j1, 251j2 at the tip side of the rear main surfaces 251b, 252b are narrower than those of the first contact convex portions 251j2, 252j2 at the base end side. The rear main surfaces 251b, 252b of the first contact convex portions 251j1, 251j2 and the second contact convex portions 252j1, 252j2 are formed in a substantially V-shaped concave shape where the bending positions are offset upward. The surfaces (rear main surface 251b) of the first contact convex portions 251j1, 251j2 and the second contact convex portions 252j1, 252j2 are in contact with the ridge lines of the second regular octagonal pyramid portion 123 such that the V-shaped tops coincide.

[0069] The attachment of the shaped part 12 to the attachment structure 2 can be performed as follows. The shaped part 12 is inserted into the opening 22 from the rear of the attachment structure 2. More specifically, the side surface 121a1 of the shaped part 12 is inserted into the opening 22 from the side of the second support 242 (in other words, from the bottom to the top of the opening 22). At this time, the side surfaces 121a4, 121a3 of the shaped part 12 are inserted along the left and right inner edges 221 of the opening 22.

[0070] Also, the insertion of the shaped part 12 into the opening 22 is performed such that the first pressing plate 251 and the second pressing plate 252 are located behind the shaped part 12. The insertion of the shaped part 12 into the opening 22 is preferably performed by tilting the upper end of the shaped part 12 forward.

[0071] More specifically, while pushing the front part of the first regular octagonal pyramid portion 122 of the shaped part 12 into contact with the rear main surface 241hb of the first support head 241h, the first pressing arm 231 and the second pressing arm 232 are elastically deformed rearward.

[0072] As the shaped part 12 is inserted, the pair of pressing arms 23 elastically deform so that the shaped part 12 can be easily inserted into the opening 22.

[0073] More specifically, looking from behind, the first pressing arm 231 is pressed against the side surface 121a5 located at the upper right end of the regular octagonal prism portion 121 and elastically deformed in the upper right direction. The second pressing arm 232 is pressed against the side surface 121a6 located at the upper left end of the regular octagonal prism portion 121 and elastically deformed in the upper left direction.

[0074] When inserted into the opening 22 of the shaped part 12, the side surface 121a1 located at the upper end of the shaped part 12 can abut against the protrusion 241c of the first support 241. Thereby, the upward movement of the shaped part 12 is restricted. In this way, the insertion of the shaped part 12 into the opening 22 can be easily inserted into a position where the upper part of the shaped part 12 is properly in contact with the pressing arm 23.

[0075] When the shaped part 12 is inserted into the opening 22, the shaped part 12 is biased downward (in the first direction) by the pressing arm 23. Then, the left and right side surfaces 121a4, 121a3 adjacent to the side surface 121a2 located at the lower end of the shaped part 12 come into contact with the inner edge 221 of the opening 22 and support the shaped part 12 against the biasing force of the pressing arm 23. The inner edge 221 that contacts and supports the side surfaces 121a4, 121a3 is the support portion 221a (first support portion). The support portion 221a is formed as a part of the inner edge 221.

[0076] At this time, the amount of protrusion of the second regular octagonal pyramid portion 123 from the opening 22 toward the rear is larger than the amount of protrusion of the first regular octagonal pyramid portion 122 from the opening 22 toward the front. Therefore, the protrusion 221b (auxiliary support portion) provided on the rear side of the inner edge 221 with which the side surfaces 121a4, 121a3 contact contacts the side surfaces 121a4, 121a3 and supports the shaped part 12. The surface of the protrusion 221b on the opening 22 side is continuous with the surface of the inner edge 221. As described above, the side surface 121a2 located at the lower end of the shaped part 12 is located above the protrusion 242a of the second support 242.

[0077] Furthermore, by contacting the second regular octagonal pyramid portion 123 of the shaped component 12, the pressing plate 25 biases the shaped component 12 forward (in the second direction). The pair of supports 24 supports the shaped component 12 against the biasing force of the pressing plate 25. The second direction is also a direction orthogonal to the plane including the first direction.

[0078] In this way, the shaped component 12 is housed in the opening 22, and the attachment of the shaped component 12 to the attachment structure 2 is completed. Note that the shaped component 12 can be removed from the attachment structure 2 by following the procedure reverse to the attachment.

[0079] According to the above embodiment, the attachment structure 2 of the mechanical clock 1 includes an inner edge 221 provided at the opening 22 in which the shaped component is housed, a pressing arm 23 provided on the inner edge 221 and serving as a first pressing portion that biases the shaped component in the first direction (for example, downward), a support portion 221a provided on the inner edge 221 and serving as a first support portion that supports the shaped component 12 against the biasing force of the pressing arm 23, a pressing plate 25 that contacts the second regular octagonal pyramid portion 123 which is one surface of the shaped component 12 and biases the shaped component 12 in a second direction (for example, forward) orthogonal to the plane including the first direction, and a support 24 that serves as a second support portion that supports the shaped component 12 against the biasing force of the pressing plate 25.

[0080] Thereby, the opening 22, the pair of pressing arms 23, the pair of supports 24, and the pair of pressing arms 23 can be integrally formed by injection molding with resin. Therefore, when attaching the shaped component 12, it is not necessary to perform operations such as removing the components constituting the attachment structure 2, and it can be easily assembled. Further, since the shaped component 12 is supported while being biased by the pressing arm 23 and the pressing plate 25, dimensional errors of the shaped component 12 can be absorbed. That is, according to the present invention, even when the dimensional error of the shaped component 12 is large, it is possible to provide the attachment structure 2 of the mechanical clock and the mechanical clock 1 that can be easily attached to the dial 3 and the like without complicated operations.

[0081] Further, the pressing arm 23 and the pressing plate 25 are provided in a set (a pair). This makes it easier to insert the pressing member.

[0082] Also, the support portion 221a is formed as a part of the inner edge 221. Further, it has a protrusion 221b as an auxiliary support portion having a surface continuous with the inner edge 221. Thereby, the shaped part 12 to be biased can be reliably supported.

[0083] Also, the protruding amount of the second regular octagonal pyramid portion 123, which is one side of the shaped part 12, from the opening 22 is larger than the protruding amount of the first regular octagonal pyramid portion 122, which is the other side, from the opening 22. Thereby, it is possible to reduce the shaped part 12 from accidentally popping out to the front side (the other side).

[0084] Also, the first support 241 and the second support 242 have protrusions 241c, 242a (the first protrusion, the second protrusion) arranged with a gap from the shaped part 12. Thereby, while further absorbing dimensional errors, it is possible to make the shaped part 12 difficult to come off by restricting the movement of the shaped part 12.

[0085] Also, the mounting structure 2 is provided on the dial 3 of the rotating plate 40 of the mechanical clock 1. Thereby, it is possible to provide the mechanical clock 1 provided with the shaped part 12 and having enhanced design.

[0086] The mounting structure according to the present invention is not limited to the mounting structures 2, 4, 6, and can be changed within the scope of the gist thereof. Note that the mounting structures 2, 4, 6 are not limited to being provided on the dial 3.
