[0004] The structure of a conventional catch 90 will be described with reference to Fig. 1. Fig. 1 is a perspective view of the conventional catch 90. The catch 90 includes a vertical plate member 91, a lower plate member 92, and an upper plate member 93. The vertical plate member 91 is joined to the lower plate member 92 and the upper plate member 93 by welding. One end of the upper plate member 93 is spaced from one end of the lower plate member 92. The other end of the upper plate member 93 is joined to the other end of the lower plate member 92 by welding.

[0005] As described above, the conventional catch 90 is constructed by welding together a plurality of plate members. However, joining the plurality of plate members requires welding within a very narrow area. In this case, highly skilled workers are required to ensure the quality of the welded portion. However, it is becoming increasingly difficult to secure highly skilled workers, and there is a risk that the quality of the welded portion will vary depending on the worker's skill. The variation in the quality of the welded portion will lead to a decrease in the reliability of the catch.

[0006] To ensure the reliability of the catch, it is possible to use a base material for the catch, but if the entire catch is simply made of base material, it tends to be heavier than if it is formed by welding multiple plate members together.

[0007] An object of the present disclosure is to provide a catch that can be made lighter.

[0008] The receiving seat for mounting a functional component for a railway vehicle according to the present disclosure comprises a first member and a second member. The first member includes a first vertical plate, a first lower plate, and a first upper plate. The first lower plate is connected to the lower end of the first vertical plate. The first upper plate is connected to the upper end of the first vertical plate. When viewed from the surface side of the first vertical plate, one end of the first upper plate is spaced apart from the first lower plate, and the other end is connected to the first lower plate. The second member includes a second vertical plate, a second lower plate, and a second upper plate. The second vertical plate is disposed opposite the first vertical plate. The second lower plate is connected to the lower end of the second vertical plate. The second upper plate is connected to the upper end of the second vertical plate. When viewed from the surface side of the second vertical plate, one end of the second upper plate is spaced apart from the second lower plate, and the other end is connected to the second lower plate. One end of the first lower plate is connected to one end of the second lower plate. A portion of the first lower plate other than one end and a portion of the second lower plate other than one end are at least partially separated from each other. One end of the first upper plate is connected to one end of the second upper plate. A portion of the first upper plate other than one end and a portion of the second upper plate other than one end are at least partially separated from each other.

[0009] According to the catch seat according to the present disclosure, it is possible to provide a catch seat that can be made lighter.

FIG. 3 is a front view of the catch seat according to the first embodiment. FIG. 4 is a bottom view of the catch seat according to the first embodiment. FIG. 5 is a side view of a catch seat according to the second embodiment. FIG. 6 is a side view of a catch seat according to the second embodiment. FIG. 7 is a side view of a catch seat according to a modified example of the second embodiment. FIG. 8 is a side view of a catch seat according to the third embodiment. FIG. 9 is a side view of a catch seat according to the third embodiment. FIG. 10 is a perspective view of a catch seat according to a modified example of each embodiment.

[0011] A receiving seat for mounting a functional component for a railway vehicle according to an embodiment includes a first member and a second member. The first member includes a first vertical plate, a first lower plate, and a first upper plate. The first lower plate is connected to the lower end of the first vertical plate. The first upper plate is connected to the upper end of the first vertical plate. When viewed from the front surface side of the first vertical plate, one end of the first upper plate is spaced apart from the first lower plate, and the other end is connected to the first lower plate. The second member includes a second vertical plate, a second lower plate, and a second upper plate. The second vertical plate is disposed opposite the first vertical plate. The second lower plate is connected to the lower end of the second vertical plate. The second upper plate is connected to the upper end of the second vertical plate. When viewed from the front surface side of the second vertical plate, one end of the second upper plate is spaced apart from the second lower plate, and the other end is connected to the second lower plate. One end of the first lower plate is connected to one end of the second lower plate. A portion of the first lower plate other than one end and a portion of the second lower plate other than one end are at least partially separated from each other. One end of the first upper plate is connected to one end of the second upper plate. A portion of the first upper plate other than one end and a portion of the second upper plate other than one end are at least partially separated from each other (first configuration).

[0012] The receiving seat according to the first configuration includes a first member and a second member. A portion of the first lower plate of the first member other than one end and a portion of the second lower plate of the second member other than one end are at least partially separated from each other. That is, the first lower plate and the second lower plate include portions that are separated from each other. Similarly, a portion of the first upper plate of the first member other than one end and a portion of the second upper plate of the second member other than one end are at least partially separated from each other. That is, the first upper plate and the second upper plate include portions that are separated from each other. Therefore, compared to when the first lower plate and the second lower plate are entirely connected and when the first upper plate and the second upper plate are entirely connected, it is possible to reduce the amount of material used, thereby achieving weight reduction.

[0013] In the first configuration, the first member and the second member may be separate members. In this case, one end of the first lower plate may be joined to one end of the second lower plate by welding. Furthermore, one end of the first upper plate may be joined to one end of the second upper plate by welding (second configuration).

[0014] In the second configuration, the first member and the second member are separate bodies, and in this case, the first member and the second member can be molded separately.

[0015] In the receiving seat of the first or second configuration, the lower surface of the first lower plate and the lower surface of the second lower plate may each include a flat surface (third configuration).

[0016] In the seat of any one of the first to third configurations, the functional component is, for example, a brake caliper, a unit brake, a motor, or a gear device (fourth configuration).

[0017] In any of the first to fourth configurations, the seat may include a rib. The rib is provided on at least one of the first vertical plate and the second vertical plate (fifth configuration).

[0018] The receiving seat of the fifth configuration may have the following configuration: the rib is provided on the first vertical plate; and bolt holes for fastening functional components with bolts are provided on the first lower plate. When the length from one end of the first lower plate to the center position of the bolt holes is L1, the lower end of the rib provided on the first vertical plate is located within a range of 1 / 5 × L1 to 1 / 2 × L1 from the end of the first lower plate (sixth configuration).

[0019] The receiving seat of the fifth or sixth configuration may have the following configuration: the rib is provided on the second vertical plate; bolt holes for fastening functional components with bolts are provided on the second lower plate; and when the length from one end of the second lower plate to the center position of the bolt holes is L2, the lower end of the rib provided on the second vertical plate is located within a range of 1 / 5 × L2 or more and 1 / 2 × L2 or less from the end of the second lower plate (seventh configuration).

[0020] In the seat of any one of the fifth to seventh configurations, the rib may be provided on the first vertical plate. The rib provided on the first vertical plate may be connected to the first lower plate and the first upper plate (eighth configuration).

[0021] In the seat of any of the fifth to seventh configurations, the rib may be provided on the first vertical plate. The rib provided on the first vertical plate may not be connected to one or both of the first lower plate and the first upper plate (ninth configuration).

[0022] In the seat of any of the fifth to ninth configurations, the rib may be provided on the second vertical plate. The rib provided on the second vertical plate may be connected to the second lower plate and the second upper plate (tenth configuration).

[0023] In the seat of any of the fifth to ninth configurations, the rib may be provided on the second vertical plate. The rib provided on the second vertical plate may not be connected to one or both of the second lower plate and the second upper plate (eleventh configuration).

[0024] In the receiving seat of any of the first to eleventh configurations, a through hole may be formed in at least one of the first vertical plate and the second vertical plate (twelfth configuration).

[0025] In the catch seat according to the twelfth configuration, a through hole is formed in at least one of the first vertical plate and the second vertical plate, thereby reducing the volume of the first vertical plate and / or the second vertical plate, thereby reducing the weight of the catch seat.

[0026] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In each drawing, the same or equivalent components are designated by the same reference numerals, and the same description will not be repeated.

[0027] [First Embodiment] Figures 2 and 3 are a perspective view and a front view, respectively, of a catch seat 10 according to this embodiment. The catch seat 10 is used to mount a functional component (not shown) for a railway vehicle. The functional component is, for example, a brake caliper, a unit brake, a motor, or a gear device. Typically, a bogie frame for a railway vehicle includes a pair of side beams (not shown) and a cross beam 80 connecting the side beams. The cross beam 80 extends in the left-right direction (width direction) of the railway vehicle. As shown in Figure 2, the catch seat 10 is joined to the cross beam 80 of the bogie frame for the railway vehicle. Figure 2 schematically shows only a portion of the cross beam 80. Figure 3 shows a view of the catch seat 10 viewed in the fore-and-aft direction from the cross beam 80 side.

[0028] Hereinafter, for convenience of explanation, the up-down direction of the railway vehicle when the support seat 10 is joined to the cross beam 80 will be simply referred to as the up-down direction. Similarly, the left-right direction of the railway vehicle when the support seat 10 is joined to the cross beam 80 will be simply referred to as the left-right direction, and the front-to-rear direction (direction of travel) of the railway vehicle when the support seat 10 is joined to the cross beam 80 will be simply referred to as the front-to-rear direction.

[0029] 2 , the striker 10 is joined to the cross beam 80 from one side in the front-to-rear direction. The striker 10 and the cross beam 80 can be joined by welding, for example. In the example of FIG. 2 , the striker 10 is joined to the cross beam 80 at a welded portion W. The striker 10 includes a first member 20 and a second member 30.

[0030] The first member 20 includes a vertical plate 21 , a lower plate 22 , and an upper plate 23 .

[0031] When the catch 10 is attached to the cross beam 80, the vertical plate 21 intersects with the extension direction of the cross beam 80. The vertical plate 21 is arranged substantially along the front-to-rear direction. In this embodiment, the vertical plate 21 has a substantially constant thickness throughout the entire area in the front-to-rear direction. The lower plate 22 is connected to the lower end of the vertical plate 21. The upper plate 23 is connected to the upper end of the vertical plate 21. In other words, the lower plate 22 and the upper plate 23 are connected in the up-down direction by the vertical plate 21.

[0032] The lower plate 22 is provided along the lower end of the vertical plate 21. The upper plate 23 is provided along the upper end of the vertical plate 21. When viewed from the front side of the vertical plate 21, i.e., from the left-right direction, the upper plate 23 has one end 22a, 23a separated from the lower plate 22 and the other end 22b, 23b connected to each other. More specifically, on the side of the cross beam 80, the ends 22a, 23a of the lower plate 22 and the upper plate 23 are vertically separated from each other, while on the opposite side of the cross beam 80, the ends 22b, 23b of the lower plate 22 and the upper plate 23 are close to each other. The one end 22a is the end of the lower plate 22 on the cross beam 80 side in the front-to-rear direction, and the other end 22b is the end of the lower plate 22 opposite the cross beam 80 in the front-to-rear direction. Similarly, the one end 23a is the end of the upper plate 23 on the cross beam 80 side in the front-to-rear direction, and the other end 23b is the end of the upper plate 23 on the opposite side of the cross beam 80 in the front-to-rear direction. The lower plate 22 and the upper plate 23 form, for example, a substantially U-shape when viewed in the left-to-right direction. The dimension of the vertical plate 21 in the up-down direction is largest, for example, on the cross beam 80 side and gradually decreases as it moves away from the cross beam 80 in the front-to-rear direction.

[0033] The second member 30 is disposed next to the first member 20 in the left-right direction. The second member 30 includes a vertical plate 31, a lower plate 32, and an upper plate 33.

[0034] When the catch 10 is attached to the cross beam 80, the vertical plate 31 intersects with the extension direction of the cross beam 80. The vertical plate 31 is arranged so as to extend substantially along the front-rear direction. In this embodiment, the vertical plate 31 has a substantially constant thickness over the entire area in the front-rear direction. The vertical plate 31 is arranged opposite the vertical plate 21 of the first member 20. The vertical plate 31 faces the vertical plate 21 of the first member 20 with a gap in the left-right direction. Therefore, a space S is formed between the vertical plates 21, 31.

[0035] The lower plate 32 is connected to the lower end of the vertical plate 31. The upper plate 33 is connected to the upper end of the vertical plate 31. In other words, the lower plate 32 and the upper plate 33 are connected in the up-down direction by the vertical plate 31.

[0036] The lower plate 32 is provided along the lower end of the vertical plate 31. The upper plate 33 is provided along the upper end of the vertical plate 31. When viewed from the front side of the vertical plate 31, i.e., from the left-right direction, the upper plate 33 has one end 32a, 33a separated from the lower plate 32 and the other end 32b, 33b connected to each other. More specifically, on the side of the cross beam 80, the ends 32a, 33a of the lower plate 32 and the upper plate 33 are vertically separated from each other, while on the opposite side of the cross beam 80, the ends 32b, 33b of the lower plate 32 and the upper plate 33 are close to each other. The one end 32a is the end of the lower plate 32 on the cross beam 80 side in the front-to-rear direction, and the other end 32b is the end of the lower plate 32 opposite the cross beam 80 in the front-to-rear direction. Similarly, the one end 33a is the end of the upper plate 33 on the cross beam 80 side in the front-to-rear direction, and the other end 33b is the end of the upper plate 33 on the opposite side of the cross beam 80 in the front-to-rear direction. The lower plate 32 and the upper plate 33 form, for example, a substantially U-shape when viewed in the left-to-right direction. The dimension of the vertical plate 31 in the up-down direction is largest, for example, on the cross beam 80 side and gradually decreases as it moves away from the cross beam 80 in the front-to-rear direction.

[0037] 3 , in the first member 20, the one end 22a of the lower plate 22 and the one end 23a of the upper plate 23 have larger dimensions in the left-right direction than the vertical plate 21. Therefore, when the catch 10 is viewed from the front, the first member 20 can have a substantially I-shape. Similarly, in the second member 30, the one end 32a of the lower plate 32 and the one end 33a of the upper plate 33 have larger dimensions in the left-right direction than the vertical plate 31. Therefore, when the catch 10 is viewed from the front, the second member 30 can have a substantially I-shape.

[0038] The one end 22a of the lower plate 22 of the first member 20 is connected to the one end 32a of the lower plate 32 of the second member 30. The portions of the lower plate 22 other than the one end 22a and the portions of the lower plate 32 other than the one end 32a are at least partially separated from each other. In this embodiment, the lower plates 22 and 32 are disposed with a gap between them in the left-right direction over the entire portions other than the ends 22a and 32a.

[0039] The one end 23a of the upper plate 23 of the first member 20 is connected to the one end 33a of the upper plate 33 of the second member 30. The portion of the upper plate 23 other than the one end 23a and the portion of the upper plate 33 other than the one end 33a are at least partially separated from each other. In this embodiment, the upper plates 23 and 33 are disposed with a gap between them in the left-right direction over the entire portions other than the ends 23a and 33a.

[0040] 3, the lower plate 22 of the first member 20 includes an upper surface 221 and a lower surface 222. The upper plate 23 includes an upper surface 231 and a lower surface 232. The vertical plate 21 is connected to the upper surface 221 of the lower plate 22 and the lower surface 232 of the upper plate 23. On the other end 22b (FIG. 2) side of the lower plate 22, the upper plate 23 is connected to the upper surface 221 of the lower plate 22, for example.

[0041] The lower plate 32 of the second member 30 includes an upper surface 321 and a lower surface 322. The upper plate 33 includes an upper surface 331 and a lower surface 332. The vertical plate 31 is connected to the upper surface 321 of the lower plate 32 and the lower surface 332 of the upper plate 33. On the side of the other end 32b ( FIG. 2 ) of the lower plate 32, the upper plate 33 is connected to the upper surface 321 of the lower plate 32, for example.

[0042] The first member 20 and the second member 30 are each manufactured by, for example, forging or casting. In this case, the first member 20 and the second member 30 are separate bodies, and are molded separately. When the first member 20 and the second member 30 are separate bodies, the first member 20 may be joined to the second member 30 by welding. That is, the end 22a of the lower plate 22 of the first member 20 may be joined to the end 32a of the lower plate 32 of the second member 30 by welding. Furthermore, the end 23a of the upper plate 23 of the first member 20 may be joined to the end 33a of the upper plate 33 of the second member 30 by welding.

[0043] When the first member 20 is manufactured by forging or casting, the lower plate 22 and the upper plate 23 are provided integrally with the vertical plate 21. That is, the lower plate 22 and the upper plate 23 are each continuous with the vertical plate 21, and no joints, such as welds, exist between the lower plate 22 and the upper plate 23 and the vertical plate 21. When the first member 20 is manufactured by forging or casting, the lower plate 22 is also provided integrally with the upper plate 23. That is, the lower plate 22 is continuous with the upper plate 23 at an end 22b (FIG. 2) opposite the cross beam 80, and no joints, such as welds, exist between the end 22b of the lower plate 22 and the end 23b (FIG. 2) of the upper plate 23.

[0044] Similarly, when the second member 30 is manufactured by forging or casting, the lower plate 32 and the upper plate 33 are provided integrally with the vertical plate 31. That is, the lower plate 32 and the upper plate 33 are each continuous with the vertical plate 31, and no joints, such as welds, exist between the lower plate 32 and the vertical plate 31 and between the lower plate 32 and the upper plate 33 and between the upper plate 33 and the vertical plate 31. When the second member 30 is manufactured by forging or casting, the lower plate 32 is also provided integrally with the upper plate 33. That is, the lower plate 32 is continuous with the upper plate 33 at an end 32b (FIG. 2) opposite the cross beam 80, and no joints, such as welds, exist between the end 32b of the lower plate 32 and the end 33b (FIG. 2) of the upper plate 33.

[0045] FIG. 4 is a bottom view of the seat 10. Referring to FIG. 4, functional components for a railway vehicle are attached to, for example, the bottom surface 222 of the bottom plate 22 and the bottom surface 322 of the bottom plate 32. In this case, preferably, the bottom surfaces 222, 322 each include a flat surface. When the first member 20 and the second member 30 are manufactured by forging or casting, the bottom surfaces 222, 322 immediately after forging or casting have a draft angle in the stamping direction (left-right direction) of the die. Therefore, at least the portions of the bottom surfaces 222, 322 where the functional components are attached are machined flat, for example.

[0046] At least one bolt hole BH for fastening a functional component with a bolt may be provided in at least one of the lower plates 22 and 32. In the example of Fig. 4, a plurality of bolt holes BH are provided in each of the lower plates 22 and 32. In each of the lower plates 22 and 32, the bolt holes BH are arranged side by side in the front-to-rear direction, for example.

[0047] The lower plate 22 may include a curved portion 223. The curved portion 223 has a shape recessed inward of the lower plate 22. Specifically, the curved portion 223 has an arc shape recessed inward in the left-right direction. The curved portion 223 may be recessed inward in the left-right direction from the center of a bolt hole BH provided in the lower plate 22. In this case, the dimension x1 in the left-right direction from the innermost portion of the curved portion 223 to the center of the bolt hole BH may be 3.25 × h1 or less, where h1 is the thickness of the lower plate 22. Here, the thickness h1 refers to the thickness of the lower plate 22 at the end 22b. In the case where the lower plate 22 has multiple bolt holes BH, as in the present embodiment, the dimension x1 is the dimension in the left-right direction from the innermost portion of the curved portion 223 to the center of the bolt hole BH closest to the end 22b.

[0048] Similarly, the lower plate 32 may include a curved portion 323. The curved portion 323 has a shape recessed inward of the lower plate 32. Specifically, the curved portion 323 has an arc shape recessed inward in the left-right direction. The curved portion 323 may be recessed inward in the left-right direction from the center of a bolt hole BH provided in the lower plate 32. In this case, the dimension x2 in the left-right direction from the innermost portion of the curved portion 323 to the center of the bolt hole BH may be 3.25 × h2 or less, where h2 is the thickness of the lower plate 32. Here, the thickness h2 refers to the thickness of the lower plate 32 at the end 32b. In the case where the lower plate 32 has multiple bolt holes BH, as in the present embodiment, the dimension x2 is the dimension in the left-right direction from the innermost portion of the curved portion 323 to the center of the bolt hole BH closest to the end 32b.

[0049] [Effect] The catch 10 according to this embodiment includes a first member 20 and a second member 30. The lower plate 22 of the first member 20, other than the one end 22a, and the lower plate 32 of the second member 30, other than the one end 32a, are at least partially separated from each other. That is, the lower plate 22 and the lower plate 32 include portions that are separated from each other. Similarly, the upper plate 23 of the first member 20, other than the one end 23a, and the upper plate 33 of the second member 30, other than the one end 33a, are at least partially separated from each other. That is, the upper plates 23 and the upper plates 33 include portions that are separated from each other. Therefore, compared to when the lower plate 22 and the lower plate 32 are entirely connected in the front-rear direction and when the upper plate 23 and the upper plate 33 are entirely connected in the front-rear direction, it is possible to reduce the amount of material used, thereby achieving weight reduction.

[0050] In the first member 20, the lower plate 22 and the upper plate 23 may be provided integrally with the vertical plate 21, or the lower plate 22 may be provided integrally with the upper plate 23. In the second member 30, the lower plate 32 and the upper plate 33 may be provided integrally with the vertical plate 31, or the lower plate 32 may be provided integrally with the upper plate 33. In this case, it is not necessary to weld a plurality of plate members together in the manufacture of the first member 20 and the second member 30. Therefore, the striker 10 of this embodiment can reduce the amount of welding compared to the conventional striker 90 ( FIG. 1 ), and is therefore highly reliable.

[0051] The first member 20 may be a separate member from the second member 30. In this case, the first member 20 and the second member 30 can be molded separately.

[0052] The surfaces of the receiving seat 10 to which the functional components of the railway vehicle are attached are preferably flat. The functional components are attached, for example, to the lower surface 222 of the lower plate 22 and the lower surface 322 of the lower plate 32. In this case, it is preferable that the lower surfaces 222 and 322 each include a flat surface. This makes it easier to attach the functional components to the lower surfaces 222 and 322.

[0053] In the catch 10 according to this embodiment, the lower plates 22, 32 each include a curved portion 223, 323 that is concave inward in the left-right direction and has an arc shape. This reduces the volume of the lower plates 22, 32 compared to when the lower plates 22, 32 do not include the curved portion 223, 323. This allows the catch 10 to be made lighter.

[0054] [Second Embodiment] Figures 5 and 6 are side views of a catch 10A according to a second embodiment. Figure 5 is a side view of the catch 10A seen from the first member 20 side. Figure 6 is a side view of the catch 10A seen from the second member 30 side. The catch 10A of this embodiment differs from the catch 10 of the first embodiment (Figures 2 to 4) in that it includes ribs 24, 34.

[0055] 5, the ribs 24 are provided on the vertical plate 21. The ribs 24 protrude in the left-right direction from the vertical plate 21. In the example of FIG. 5, the ribs 24 are provided on the side of the vertical plate 21 opposite to the second member 30 (FIG. 6). However, the ribs 24 may be provided on the second member 30 side of the vertical plate 21. Furthermore, the ribs 24 may be provided on both the second member 30 side and the side opposite to the second member 30 side of the vertical plate 21. The ribs 24 are provided integrally with the vertical plate 21, for example. The ribs 24 may be connected to the lower plate 22 and the upper plate 23.

[0056] When the length from the end of the lower plate 22 on the end 22a side to the center of the bolt hole BH is defined as L1, the lower end 24a of the rib 24 is preferably located within a range of 1 / 5 × L1 to 1 / 2 × L1 from the end of the lower plate 22 on the end 22a side. In other words, the center of the thickness of the lower end 24a of the rib 24 is located within a range of 1 / 5 × L1 to 1 / 2 × L1 from the end of the lower plate 22 on the end 22a side. Here, length L1 refers to the dimension in the front-to-rear direction from the end of the lower surface 222 on the end 22a side of the lower plate 22 to the center of the bolt hole BH (see FIG. 4). In the present embodiment, when the lower plate 22 has multiple bolt holes BH, length L1 refers to the length from the end of the lower surface 222 (FIG. 4) on the end 22a side of the lower plate 22 on the end 22b side to the center of the bolt hole BH closest to the end 22b side. In the front-rear direction, the entire lower end 24a of the rib 24 may be included within a range of ⅕×L1 to ½×L1 from the end of the lower plate 22 on the end 22a side. The rib 24 may be provided, for example, on the vertical plate 21 at a position corresponding to the bolt hole BH of the lower plate 22 closest to the end 22a.

[0057] 6 , the ribs 34 are provided on the vertical plate 31. The ribs 34 protrude in the left-right direction from the vertical plate 31. In the example of FIG. 6 , the ribs 34 are provided on the side of the vertical plate 31 opposite to the first member 20 ( FIG. 5 ). However, the ribs 34 may be provided on the first member 20 side of the vertical plate 31. Furthermore, the ribs 34 may be provided on both the first member 20 side and the side opposite to the first member 20 side of the vertical plate 31. The ribs 34 are provided integrally with the vertical plate 31, for example. The ribs 34 may be connected to the lower plate 32 and the upper plate 33.

[0058] When the length from the end of the lower plate 32 closest to the end 32a to the center of the bolt hole BH is defined as L2, the lower end 34a of the rib 34 is preferably located within a range of 1 / 5 × L2 to 1 / 2 × L2 from the end of the lower plate 32 closest to the end 32a. In other words, the center of the thickness of the lower end 34a of the rib 34 is located within a range of 1 / 5 × L2 to 1 / 2 × L2 from the end of the lower plate 32 closest to the end 32a. Here, length L2 refers to the dimension in the front-to-rear direction from the end of the lower surface 322 of the lower plate 32 closest to the end 32a to the center of the bolt hole BH (see FIG. 4). When multiple bolt holes BH are formed in the lower plate 32, as in this embodiment, length L2 is the length from the end of the lower surface 322 (FIG. 4) of the lower plate 32 closest to the end 32a to the center of the bolt hole BH closest to the end 32b. In the front-to-rear direction, the entire lower end 34a of the rib 34 may be within a range of ⅕ × L2 or more and ½ × L2 or less from the end of the lower plate 32 on the end 32a side. The center position of the thickness of the lower end 34a of the rib 34 may substantially coincide with the center position of the bolt hole BH closest to the end 32a. The rib 34 may be provided, for example, on the vertical plate 31 at a position corresponding to the bolt hole BH closest to the end 32a of the lower plate 32.

[0059] In this embodiment, the rib 24 is provided on the vertical plate 21 so that its lower end 24a is located within a range of 1 / 5 × L1 to 1 / 2 × L1 from the end of the lower plate 22 on the end 22a side. Similarly, the rib 34 is provided on the vertical plate 31 so that its lower end 34a is located within a range of 1 / 5 × L2 to 1 / 2 × L2 from the end of the lower plate 32 on the end 32a side. In this case, the ribs 24, 34 are likely to be located in positions where high stress is generated in the striker 10A. For example, if the lower plates 22, 32 have multiple bolt holes BH, if the ribs 24, 34 are located within the above range, the ribs 24, 34 are likely to be located in positions corresponding to the bolt holes BH closest to the ends 22a, 32a (closer to the cross beam 80) among the multiple bolt holes BH. Here, because the striker 10A receives loads from functional components at the positions of the bolt holes BH, relatively high stress is likely to be generated at the positions of the striker 10A corresponding to the bolt holes BH. Therefore, by providing the ribs 24, 34 within the above range, the rigidity of the receiving seat 10A can be improved at positions where the generated stress is relatively large, and the strength of the receiving seat 10A can be ensured.

[0060] In the present embodiment, the rib 24 is connected to the lower plate 22 and the upper plate 23. However, the rib 24 does not have to be connected to one or both of the lower plate 22 and the upper plate 23. For example, as shown in FIG. 7 , the rib 24 may be connected to the upper plate 23 but not connected to the lower plate 22. Also, although not shown, the rib 24 may be connected to the lower plate 22 but not connected to the upper plate 23. Furthermore, the rib 24 does not have to be connected to either the lower plate 22 or the upper plate 23. Like the rib 24, the rib 34 does not have to be connected to one or both of the lower plate 32 and the upper plate 33.

[0061] In this embodiment, the ribs 24, 34 are provided on both the vertical plates 21, 31. However, the ribs 24, 34 may be provided on only one of the vertical plates 21, 31. That is, the ribs 24 may be provided on the vertical plate 21, and the ribs 34 may not be provided on the vertical plate 31. Conversely, the ribs 34 may be provided on the vertical plate 31, and the ribs 24 may not be provided on the vertical plate 21.

[0062] 8 and 9 are side views of a catch 10B according to a third embodiment. Fig. 8 is a side view of the catch 10B seen from the first member 20 side. Fig. 9 is a side view of the catch 10B seen from the second member 30 side. The catch 10B of this embodiment has different shapes of the vertical plates 21, 31 compared to the catch 10A of the second embodiment (Figs. 5 and 6).

[0063] 8, at least one through hole 211 is formed in the vertical plate 21. In this embodiment, two through holes 211 are formed in the vertical plate 21. Each of the through holes 211 penetrates the vertical plate 21 in the plate thickness direction.

[0064] The through holes 211 are preferably formed in positions on the vertical plate 21 where stress generated when a functional component is attached to the receiving seat 10B and operated is relatively small. For example, when a rib 24 is provided on the vertical plate 21, the through holes 211 may be formed in positions different from the rib 24 in the front-rear direction. In the example of Fig. 8, one through hole 211 is disposed on one side of the rib 24 in the front-rear direction, and the other through hole 211 is disposed on the other side of the rib 24 in the front-rear direction.

[0065] The shape of the through hole 211 can be selected as appropriate. The through hole 211 may be circular, elliptical, polygonal, or any other shape when viewed from the side of the catch 10B. When the vertical plate 21 has multiple through holes 211 as in this embodiment, these through holes 211 may have the same shape or different shapes. Furthermore, the sizes of the through holes 211 may be the same or different.

[0066] 9 , at least one through hole 311 is formed in the vertical plate 31. In this embodiment, two through holes 311 are formed in the vertical plate 31. Each of the through holes 311 penetrates the vertical plate 31 in the plate thickness direction.

[0067] The through holes 311 are preferably formed in positions on the vertical plate 31 where stress generated when a functional component is attached to the catch 10B and operated is relatively small. For example, when a rib 34 is provided on the vertical plate 31, the through holes 311 may be formed in positions different from the rib 34 in the front-rear direction. In the example of Fig. 9, one through hole 311 is disposed on one side of the rib 34 in the front-rear direction, and the other through hole 311 is disposed on the other side of the rib 34 in the front-rear direction.

[0068] The shape of the through hole 311 can be selected as appropriate. The through hole 311 may be circular, elliptical, polygonal, or any other shape when viewed from the side of the catch 10B. When the vertical plate 31 has multiple through holes 311 as in this embodiment, the through holes 311 may have the same shape or different shapes. The sizes of the through holes 311 may also be the same or different. Furthermore, the through holes 311 may have the same shape as the through holes 211 ( FIG. 8 ) provided in the vertical plate 21 or may have a different shape. The sizes of the through holes 311 may also be the same as or different from the through holes 211.

[0069] In the catch 10B according to this embodiment, through holes 211, 311 are formed in the vertical plates 21, 31. This allows the volume of the vertical plates 21, 31 to be reduced, thereby making it possible to reduce the weight of the catch 10B.

[0070] 8 and 9, two through holes 211, 311 are formed in each of the vertical plates 21, 31. However, the number of through holes formed in each of the vertical plates 21, 31 is not limited to this. Each of the vertical plates 21, 31 may have a single through hole 211, 311, or three or more through holes 211, 311.

[0071] In this embodiment, the through holes 211, 311 are formed in both the vertical plates 21, 31. However, the through holes 211, 311 may be formed in only one of the vertical plates 21, 31. That is, the through hole 211 may be formed in the vertical plate 21, and the through hole 311 may not be formed in the vertical plate 31. Conversely, the through hole 311 may be formed in the vertical plate 31, and the through hole 211 may not be formed in the vertical plate 21.

[0072] In this embodiment, the ribs 24, 34 are provided on both the vertical plates 21, 31. However, the ribs 24, 34 do not necessarily have to be provided on one or both of the vertical plates 21, 31.

[0073] Although the embodiments of the present disclosure have been described above, the present disclosure is not limited to the above-described embodiments, and various modifications are possible without departing from the spirit of the present disclosure.

[0074] In the examples of the above-described embodiments, the first member 20 is separate from the second member 30. However, the first member 20 may be provided integrally with the second member 30. In this case, the first member 20 is continuous with the second member 30, and there is no joint, which is a welded portion, between the first member 20 and the second member 30. Such a first member 20 and second member 30 can be manufactured, for example, by a 3D printer or additive manufacturing. In this case, the amount of welding can be reduced compared to the examples of the above-described embodiments.

[0075] In the above embodiments, the lower plate 22 of the first member 20 is connected to the end 32a of the lower plate 32 of the second member 30 at the end 22a on the cross beam 80 side. The lower plate 22 and the lower plate 32 are separated from each other in portions other than the ends 22a and 32a. However, the lower plate 22 and the lower plate 32 may be connected at a portion other than the ends 22a and 32a. FIG. 10 is a perspective view of a strike plate 10 according to a modified example. In the example of FIG. 10, the lower plate 22 is also connected to the end 32b of the lower plate 32 at the end 22b opposite the end 22a. Furthermore, similar to the lower plates 22 and 32, the upper plate 23 of the first member 20 and the upper plate 33 of the second member 30 may be connected at a portion other than the ends 23a and 33a.

[0076] In the above-described embodiments, the thickness of the vertical plates 21, 31 is constant throughout the entire area in the front-to-rear direction. However, the thickness of the vertical plates 21, 31 may vary throughout the front-to-rear direction. For example, when the bolt holes BH are provided in the lower plate 22, the thickness of at least a portion of the vertical plates 21 within a range of 1 / 5 × L1 to 1 / 2 × L1 from the end of the lower plate 22 on the end 22a side in the front-to-rear direction may be greater than the thickness of the vertical plates 21 at other positions. Similarly, when the bolt holes BH are provided in the lower plate 32, the thickness of at least a portion of the vertical plates 31 within a range of 1 / 5 × L2 to 1 / 2 × L2 from the end of the lower plate 32 on the end 32a side in the front-to-rear direction may be greater than the thickness of the vertical plates 31 at other positions.
