The outer conductor has a cylindrical portion that is electrically connected to the other outer conductor. The plate-shaped conductive member extends throughout the inside and outside of the housing and has a first connection portion that is electrically connected to a grounding member on the outside of the housing and a second connection portion that is electrically connected to the cylindrical portion on the inside of the housing.

[0004] However, as in the present invention Figure 10 As shown, the following structure can also be adopted: the grounding connection member 1 (the plate-shaped conductive member of Patent Document 1, equivalent to the member of the housing-side grounding connection portion of Patent Document 2) extends upward from the holding portion 5 held in the housing 2 and obliquely to the left from the housing 2, and the upper end of the grounding connection member 1 contacts the grounding member 3 from below. The holding portion 5 has a locking portion (not shown) that locks into the housing 2. Here, the grounding connection member 1, through contact with the grounding member 3, moves away from the rotational direction of the housing 2 (refer to...) Figure 10 Arrow B) is subjected to force. At this time, the retaining part 5 becomes the rotation center of the grounding connection member 1. Therefore, it is possible to apply a large load to the retaining part 5, and the locking position of the locking part may shift relative to the housing 2, etc., weakening the locking force of the grounding connection member 1. When the locking force of the grounding connection member 1 weakens, the shielding performance of the connector 4 may decrease.

[0006] The shielded connector of the present invention comprises: Insulating casing; A conductive outer conductor is held within the housing; and A conductive, plate-shaped connecting member is connected to the outer conductor, wherein... The housing has a slot that opens on one side of the housing. The connecting member has: a base portion that allows the board surface to be arranged along one side surface of the housing; an elastically deformable extension portion that extends from a connecting portion connected to the base portion to a contact portion that contacts an external grounding member; and a locking piece that is bent from the base portion and arranged in the groove, wherein the extension portion is inclined toward the contact portion in a direction away from the one side surface of the housing, the locking piece has a plurality of locking protrusions that lock to an inner surface of the groove.

[0009] [Explanation of Embodiments of the Invention] First, an embodiment of the present application will be explained. (1) The shield connector of the present application comprises: an insulating housing; an electrically conductive outer conductor held by the housing; and an electrically conductive plate-shaped connection member connected to the outer conductor, the housing having a groove open on one side surface of the housing, the connection member having: a base portion having a plate surface arranged along the one side surface of the housing; an elastically deformable extension portion extending from a link portion connected to the base portion to a contact portion that contacts an external grounding member; and a locking piece bent from the base portion and arranged in the groove, the extension portion being inclined toward the contact portion in a direction away from the one side surface of the housing, and the locking piece having a plurality of locking protrusions that lock to an inner surface of the groove.

[0010] According to the above (1), by the contact of the connection member with the external grounding member, even if a force in a rotational direction away from the one side surface of the housing is applied to the connection member, the locking force of the plurality of locking protrusions can resist the force. Therefore, the rotation of the connection member can be suppressed.

[0011] (2) In the shield connector described in the above (1), it is preferable that a part of the plurality of locking protrusions protrude in one direction of a plate thickness direction of the locking piece, and another part of the plurality of locking protrusions protrude in another direction of the plate thickness direction of the locking piece.

[0012] According to the above (2), when the locking piece is inserted into the groove, a part of the locking protrusions lock to one of the inner surfaces of the groove, and another part of the locking protrusions lock to another of the inner surfaces of the groove. Therefore, the sliding marks (movement tracks) of the respective parts and the other part of the locking protrusions can be prevented from overlapping on the inner surfaces of the groove, and the respective locking protrusions can be stably held to the inner surfaces of the groove.

[0013] (3) In the shield connector described in the above (2), it is preferable that the plurality of locking protrusions are arranged on the plate surface of the locking piece at positions on a straight line extending in a bending direction of the locking piece.

[0014] According to the above (3), the plate width (width dimension in a direction orthogonal to the bending direction of the locking piece on the plate surface of the locking piece) of the locking piece can be reduced, and the shield connector can be corresponded to the miniaturization.

[0015] (4) In the shield connector described in the above (1), it is preferable that the plate width direction of the base portion is toward a width direction of the one side surface of the housing, the groove is provided at both end portions in the width direction on the one side surface of the housing, the locking piece is bent in pairs from both end portions in the plate width direction of the base portion, and the base portion is gradually formed in a wide width from the link portion toward the locking piece.

[0016] According to the above (4), when the connecting member and the external grounding member contact, stress generated at the base portion is dispersed to the wide portion from the connecting portion toward the locking piece. Therefore, the connecting member is less likely to rotate toward the side surface of the housing.

[0017] (5) In the shielded connector according to any one of (1) to (4), it is preferable that the extension portion has a root portion including the connecting portion, a tip portion including the contact portion, and an intermediate portion disposed between the root portion and the tip portion, the root portion has a plate width dimension larger than a plate width dimension of the tip portion, and the intermediate portion is gradually formed narrower from the root portion toward the tip portion.

[0018] According to the above (5), since the root portion has a plate width dimension larger than a plate width dimension of the tip portion, the strength of the root portion can be improved compared to a case where the root portion and the tip portion have the same plate width dimension. In addition, since the tip portion has a plate width dimension smaller than a plate width dimension of the root portion, the elastic force of the connecting member can be reduced compared to a case where the root portion and the tip portion have the same plate width dimension. Further, by the intermediate portion being gradually formed narrower from the root portion toward the tip portion, stress generated at the intermediate portion can be dispersed.

[0019] (6) In the shielded connector according to any one of (1) to (5), it is preferable that the extension portion extends in a straight line from the connecting portion to the contact portion.

[0020] According to the above (6), the processing procedure of the connecting member can be easily simplified. Therefore, cost reduction of the shielded connector can be achieved.

[0021] [Details of Embodiments of the Invention] A specific example of an embodiment of the present application will be described below with reference to the drawings. Furthermore, the present application is not limited to this example, but is shown by claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0022] [Embodiment 1] Referring to Figures 1 to 9 A specific example of Embodiment 1 of the present application will be described. As shown in Figure 1 The shielded connector 10 has an inner conductor 11, a dielectric body 12, an outer conductor 13, a housing 14, and a connecting member 15. As shown in Figure 2As shown, the connecting member 15 is electrically connected to the external grounding member 16. The grounding member 16 is a metal frame. The shielded connector 10 is a board connector mounted on the circuit board 17. Furthermore, in each figure, the X direction, Y direction, and Z direction represent the front, right, and top directions, respectively. In the case of this embodiment 1, the top direction is the side where the counterpart connector 34 engages with the shielded connector 10. The left-right direction aligns with the width direction of the housing 14. Furthermore, the reference points for these directions may not necessarily align with the reference points for the direction of the shielded connector 10 when mounted in a vehicle (not shown) or similar vehicle.

[0023] (Inner conductor 11) like Figure 1 As shown, the inner conductor 11 is a conductive metal plate, in the form of a tab or pin. In this embodiment 1, the shielded connector 10 has two inner conductors 11 of the same shape. Each inner conductor 11 has a mating connection portion 18, a relay portion 19, and a substrate connection portion 20. The mating connection portion 18 extends in the vertical direction. Figure 2 As shown, the lower part of the peer connection portion 18 is held in place by the dielectric body 12. The upper part of the peer connection portion 18 protrudes upwards from the dielectric body 12. A relay portion 19 is disposed between the peer connection portion 18 and the substrate connection portion 20. The relay portion 19 extends forward and downward from the lower end of the peer connection portion 18. The substrate connection portion 20 extends forward from the lower end of the relay portion 19. The substrate connection portion 20 is disposed along the upper surface of the circuit board 17 and is soldered to the conductive portion of the circuit board 17.

[0024] (Dielectric 12) Dielectric 12 is made of synthetic resin. For example... Figure 2 As shown, the dielectric body 12 has an L-shaped block when viewed from the side. The dielectric body 12 has a terminal mounting portion 21 and a terminal lead-out portion 22. The terminal mounting portion 21 is shaped to extend in the vertical direction. The terminal lead-out portion 22 is connected to the lower end of the terminal mounting portion 21 and extends forward.

[0025] The terminal mounting portion 21 has a plurality of mounting holes 23. Each mounting hole 23 extends vertically. In the case of this embodiment 1, two mounting holes 23 are provided at intervals in the left-right direction. The counterpart connection portion 18 of the inner conductor 11 is inserted into the mounting hole 23 from below. The lower part of the counterpart connection portion 18 is pressed in and held in the mounting hole 23.

[0026] (Outer conductor 13) The outer conductor 13 is conductive and is formed by die casting. For example... Figure 2 As shown, a dielectric body 12 containing an inner conductor 11 is disposed inside the outer conductor 13. The outer conductor 13 has a bottom 24, a flange 25, and a cylindrical portion 26 in sequence from bottom to top.

[0027] As shown in Figure 3 , the flange portion 25 is flat-plate shaped, and has an outer shape that is a quadrangle in plan view. The bottom portion 24 protrudes downward from the flange portion 25. The bottom portion 24 is in the shape of a door in plan view, and is open to the front and the lower side.

[0028] As shown in Figure 4 , the cylindrical portion 26 protrudes upward from the flange portion 25. The cylindrical portion 26 is in the shape of a square tube with rounded corners, and is open to the upper side. As shown in Figure 2 , the outer conductor 13 has an insertion hole 27 that penetrates in the vertical direction from the flange portion 25 to the cylindrical portion 26.

[0029] The terminal mounting portion 21 of the dielectric body 12 is inserted into the insertion hole 27 from the lower side of the outer conductor 13 through the inner side of the bottom portion 24. The upper end surface of the terminal mounting portion 21 is disposed at the upper-middle portion of the insertion hole 27 of the cylindrical portion 26. The upper end portion of the counterpart connecting portion 18 of the inner conductor 11 protrudes from the upper end surface of the terminal mounting portion 21, and is disposed in the insertion hole 27 of the cylindrical portion 26. The relay portion 19 of the inner conductor 11 protrudes downward from the insertion hole 27 of the flange portion 25, and is disposed on the inner side of the bottom portion 24 except for the lower end portion. The substrate connecting portion 20 of the inner conductor 11 is disposed on the front side of the inner side of the bottom portion 24, and is connected to the circuit substrate 17. The terminal lead-out portion 22 of the dielectric body 12 is housed in the inner side of the bottom portion 24.

[0030] As shown in Figure 4 , a plurality of protrusions 28 are formed protruding on the upper surface of the flange portion 25. Each of the protrusions 28 is disposed at intervals in the circumferential direction on the outer peripheral surface of the cylindrical portion 26. Each of the protrusions 28 extends in the vertical direction and is connected to the outer peripheral surface of the cylindrical portion 26. The protrusions 28 can be caught in the recesses 29 of the housing 14 described later.

[0031] A plurality of substrate fitting portions 30 are formed protruding on the lower surface of the flange portion 25. As shown in Figure 3 , each of the substrate fitting portions 30 is in the shape of a cylinder, and a total of five are formed. In each of the substrate fitting portions 30, four of the substrate fitting portions 30 are connected to the four corners of the bottom portion 24 from the lower surface of the flange portion 25 to the halfway position toward the lower side, and the remaining one is connected to the left and right middle portions of the back surface of the bottom portion 24 from the lower surface of the flange portion 25 to the halfway position. As shown in Figure 2 , the lower end portion (the portion on the lower side of the bottom portion 24) of each of the substrate fitting portions 30 is positioned and inserted into the plurality of fitting holes 31 provided in the circuit substrate 17.

[0032] (Housing 14) The housing 14 is made of synthetic resin. As shown in Figure 5 , the housing 14 is in the shape of a square tube. The housing 14 has a bottom wall portion 32 and a fitting portion 33.

[0033] The bottom wall portion 32 is a plate shape in a quadrangle in plan view, and constitutes a lower end portion of the housing 14. A fitting portion 33 protrudes upward from an outer peripheral edge portion of an upper surface of the bottom wall portion 32. A counterpart connector 34 is fitted to the fitting portion 33. As shown in Figure 2 the housing 14 has a through-hole 35 extending in the vertical direction from the bottom wall portion 32 to the fitting portion 33. The cylindrical portion 26 of the outer conductor 13 is inserted into the through-hole 35 from below.

[0034] As shown in Figure 5 a plurality of recessed portions 29 are formed in a lower surface of the bottom wall portion 32. Each of the recessed portions 29 is provided in correspondence with each of the protruded portions 28. Each of the recessed portions 29 is open in the lower surface of the bottom wall portion 32, and further open in an inner peripheral surface of the through-hole 35. Each of the protruded portions 28 of the outer conductor 13 is inserted into and stopped by each of the recessed portions 29. Thus, the outer conductor 13 and the housing 14 are joined in a state in which separation in the vertical direction is suppressed.

[0035] A pair of protruded portions 36 are protrusively formed in a rear surface 58 (corresponding to one side surface of the present application) of the housing 14. Each of the protruded portions 36 is a prismatic shape. Each of the protruded portions 36 is disposed at a lower end of the rear surface 58 with a spacing in the lateral direction. Each of the protruded portions 36 is fitted to a receiving portion 37 of the connection member 15, which will be described later.

[0036] A pair of grooves 38 are formed in the lower end of the rear surface 58. Each of the grooves 38 is disposed on the rear surface 58 outside the lateral direction of each of the protruded portions 36. Each of the grooves 38 is a slit shape. The width of each of the grooves 38 is defined by the spacing of inner surfaces opposed in the lateral direction. Each of the grooves 38 extends in the front-rear direction, is open in the rear surface 58, and further open in the lower surface of the bottom wall portion 32. The inner surface of each of the grooves 38 has a first surface 39 as a wall surface on the inner side in the lateral direction and a second surface 40 as a wall surface on the outer side in the lateral direction. The first surface 39 and the second surface 40 are opposed in the lateral direction. In the state in which the outer conductor 13 and the housing 14 are joined, the lower surface opening of each of the grooves 38 is closed by the flange portion 25. The stop piece 41 of the connection member 15, which will be described later, is inserted into the groove 38.

[0037] ( Connection member 15 ) The connection member 15 is formed of a metal plate material having electrical conductivity. As shown in Figure 6 the connection member 15 has a base portion 42, a plurality of elongated portions 43 which are elastically deformable, an outer conductor connecting portion 44, and a plurality of stop pieces 41.

[0038] The base portion 42 is a flat plate shape, and the plate width direction thereof is oriented in the lateral direction. As shown in Figure 3 the base portion 42 is disposed along the rear surface 58 of the housing 14 in a manner to cover the lower end portion of the rear surface 58. The plate width of the base portion 42 (the lateral dimension of the base portion 42) is smaller than the width of the rear surface 58 of the housing 14 (the lateral dimension of the rear surface of the housing 14).

[0039] As Figure 6 illustrated, the base 42 has a pair of end portions 45 disposed at left and right end portions of the base 42 and a central portion 46 disposed at left and right central portions of the base 42. The central portion 46 has a larger up-and-down dimension than the end portions 45. The end portions 45 have a pair of receiving portions 37 left and right. Each receiving portion 37 is located at the left or right inner side of the end portion 45 and is opened in a concave shape at the lower end of the end portion 45. As Figure 3 illustrated, each protruding portion 36 of the housing 14 is fitted with each receiving portion 37 from below.

[0040] As Figure 6 illustrated, the outer conductor connecting portion 44 has a plate surface facing the up-and-down direction. The outer conductor connecting portion 44 is connected with the lower end of the central portion 46. Specifically, as Figure 2 illustrated, the outer conductor connecting portion 44 has an outer conductor contact portion 47 which is bent in a mountain shape toward the upper side in a side view and extends toward the front. A front portion of the outer conductor connecting portion 44 extends from the outer conductor contact portion 47 to the obliquely lower front side by a short distance. The outer conductor connecting portion 44 is elastically deformable in the up-and-down direction with the connected portion of the central portion 46 as a fulcrum. In the case of the present embodiment 1, the outer conductor connecting portion 44 is in contact with the lower surface of the flange portion 25 of the outer conductor 13. Thus, the outer conductor connecting portion 44 is electrically connected with the outer conductor 13.

[0041] As Figure 7 illustrated, the base 42 has a pair of inclined portions 48 which are tapered toward the upper side at the left and right end edges of each end portion 45. The base 42 is gradually formed to have a wide width from the upper side toward the lower side in a range corresponding to each inclined portion 48.

[0042] As Figure 6 illustrated, each locking piece 41 is bent (protrudes) forward from a portion of the left or right end edge of each end portion 45 which is lower than the inclined portion 48. The locking piece 41 has a plate thickness direction facing the left and right directions.

[0043] In addition, the locking piece 41 has a plurality of locking protrusions 49 which protrude toward the left and right directions as the plate thickness direction from the plate surface (left and right surfaces, front and back surfaces) of the locking piece 41. Each locking protrusion 49 is formed by, for example, die cutting such as louver processing or bending processing based on a knock-out. As Figure 8 illustrated, the rear end surface 59 of each locking protrusion 49 is the plate thickness surface (extrusion surface or cut-out surface) of each locking piece 41 and is disposed along the up-and-down direction. The outer periphery of the rear end surface 59 has a circular arc shape which bulges toward the left and right directions as viewed from the rear.

[0044] The protruding amount of each locking protrusion 49 toward the left and right directions gradually increases from the front end toward the rear end surface 59. In addition, each locking protrusion 49 has a triangular shape in a side view and the up-and-down dimension gradually increases from the front end toward the rear end surface 59.

[0045] As shown in Figure 9 each of the locking pieces 41 has a first locking protrusion 50 and a second locking protrusion 51 as the locking protrusions 49. The first locking protrusion 50 protrudes toward the inside in the left-right direction (the left and right center side of the housing 14) of the locking piece 41. The second locking protrusion 51 protrudes toward the outside in the left-right direction (the side away from the left and right center of the housing 14) of the locking piece 41. As shown in Figure 6 the first locking protrusion 50 is disposed at the front end portion of the locking piece 41. The second locking protrusion 51 is located further back than the first locking protrusion 50 and is disposed at the rear end portion of the locking piece 41. In each of the locking pieces 41, the upper and lower center portions (top portions) of the first locking protrusion 50 and the second locking protrusion 51 are each arranged in a position on a straight line in the front-rear direction.

[0046] As shown in Figure 7 each of the locking pieces 41 is inserted from the rear into the groove 38 of the housing 14. As shown in Figure 9 the first locking protrusion 50 is engaged in and locked by the first surface 39. Likewise, the second locking protrusion 51 is engaged in and locked by the second surface 40.

[0047] As shown in Figure 6 three are arranged in the left-right direction in the connection member 15. Each of the extension portions 43 has the plate width direction oriented in the left-right direction. The extension portion 43 has a shape of a fold line extending in a straight line in a direction (obliquely upward and rearward) in which the housing 14 is gradually distanced from the rear surface 58 from the link portion 52 to the contact portion 53, which will be described later. The link portion 52 is connected to the upper end of the base portion 42 along the left-right direction. As shown in Figure 2 the extension portion 43 is connected to the base portion 42 at an obtuse angle at the link portion 52. The extension portion 43 is elastically deformable in the up-down direction with the link portion 52 as a fulcrum.

[0048] In addition, as shown in Figure 6 the extension portion 43 has a root portion 54, a tip end portion 55, and an intermediate portion 56. The root portion 54 is a portion extending from the link portion 52. The plate width dimension of each of the root portion 54 and the tip end portion 55 is constant in the extension direction of the extension portion 43. The plate width dimension of the root portion 54 is larger than the plate width dimension of the tip end portion 55. The tip end portion 55 is disposed at the end portion in the extension direction of the extension portion 43. The intermediate portion 56 is disposed between the root portion 54 and the tip end portion 55. The intermediate portion 56 is gradually formed to be narrow from the root portion 54 to the tip end portion 55.

[0049] The contact portion 53 is the upper end portion of the tip end portion 55. As shown in Figure 2 the contact portion 53 protrudes toward the ground member 16 at the upper end portion of the tip end portion 55, and the curved upper surface is brought into contact with the lower surface of the ground member 16. In the case of the present embodiment 1, the lower surface of the ground member 16 is a horizontal surface along the front-rear direction and the left-right direction.

[0050] A bent tip portion 57 is connected to the contact portion 53 of the extension portion 43. The bent tip portion 57 is the rear end of the tip portion 55, which bends downward and backward from the contact portion 53 and extends for a shorter period. In addition, the connecting member 15 is symmetrical on the left and right sides of the left and right centers of the connecting member 15.

[0051] (Assembly sequence of shielded connector 10) like Figure 2 As shown, the connecting portion 18 of the inner conductor 11 is inserted from below into the mounting hole 23 of the dielectric body 12. The dielectric body 12 is mounted on the outer conductor 13 after the inner conductor 11 is installed. Specifically, the terminal mounting portion 21 of the dielectric body 12 is inserted from below into the insertion hole 27 of the outer conductor 13. In addition, the cylindrical portion 26 of the outer conductor 13 is inserted from below into the through hole 35 of the housing 14. At this time, the upper surface of the flange portion 25 of the outer conductor 13 and the lower surface of the bottom wall portion 32 of the housing 14 are in a facing state.

[0052] After assembling the outer conductor 13 and the housing 14, as Figure 7 As shown, each locking tab 41 of the connecting member 15 is inserted from the rear into each slot 38 of the housing 14, and the connecting member 15 is mounted on the housing 14. During the insertion of each locking tab 41 relative to each slot 38, each locking protrusion 49 sometimes scrapes the inner surface (first surface 39 or second surface 40) of each slot 38, leaving a track. In the case of this embodiment 1, the first locking protrusion 50 is locked to the first surface 39, and the second locking protrusion 51 is locked to the second surface 40. Therefore, the second locking protrusion 51 will not pass through the track that could be formed on the first surface 39. Therefore, the second locking protrusion 51 is properly locked to the second surface 40.

[0053] Additionally, when the connecting member 15 is installed in the housing 14, such as Figure 3 As shown, the outer conductor connection portion 44 of the connecting member 15 is arranged along the lower surface of the flange portion 25 of the outer conductor 13. By contacting the lower surface of the flange portion 25, the connecting member 15 and the outer conductor 13 are electrically connected. Thus, the assembly of the shielded connector 10 is completed.

[0054] (Function of connecting member 15) like Figure 2 As shown, the shielded connector 10 is mounted on the circuit board 17. Furthermore, the contact portion 53 of the extension 43 contacts the lower surface of the grounding member 16 from below.

[0055] The connecting member 15, through a contact load acting below the contact portion 53, is subjected to a rotational direction away from the housing 14, with the locking piece 41 or the vicinity of the locking piece 41 as the fulcrum (see reference). Figure 2the force of the arrow A). As described above, the first locking protrusion 50 is locked to the first surface 39 of the corresponding groove 38, and the second locking protrusion 51 is locked to the second surface 40 of the corresponding groove 38 (see Figure 9 ). Each locking piece 41 is inserted into each groove 38 on the left and right sides of the housing 14, and each locking protrusion 49 is provided on each locking piece 41 in one-to-one correspondence, for a total of four. Thus, in the case of the present embodiment 1, the rotation of the connecting member 15 in the direction of the arrow A (see Figure 2 ) is suppressed by the locking action of the plurality of locking protrusions 49, and the state in which the base 42 is in face-to-face contact with the rear surface 58 of the housing 14 is maintained. In this way, by ensuring the locking force of the connecting member 15 with respect to the housing 14, the shielding performance is improved as a result.

[0056] In addition, in the case of the present embodiment 1, as shown in Figure 8 , the first locking protrusion 50 and the second locking protrusion 51 are arranged on the plate surface (the left and right surfaces of the locking piece 41, the surface face) of the locking piece 41 at positions on a straight line extending in the front-rear direction that is the bending direction of the locking piece 41. Compared to the case in which the first locking protrusion 50 and the second locking protrusion 51 are arranged offset from the positions on the straight line toward the plate width direction (the up-down direction of the locking piece 41) of the locking piece 41, the plate width dimension of the locking piece 41 can be reduced. Thus, the miniaturization of the shielded connector 10 can be accommodated.

[0057] In addition, in the case of the present embodiment 1, as shown in Figure 7 , the pair of inclined portions 48 gradually widen in the left-right direction from the linking portion 52 toward the lower side where the locking piece 41 is located. Accordingly, when the connecting member 15 comes into contact with the ground member 16, the stress generated in the base 42 can be dispersed along each inclined portion 48. Thus, the rotation of the connecting member 15 in the direction of the arrow A (see Figure 2 ) can be further suppressed.

[0058] In addition, in the case of the present embodiment 1, as shown in Figure 6 , the plate width dimension of the tip end portion 55 is smaller than the plate width dimension of the root portion 54. Thus, compared to the case in which the plate width dimensions of the root portion 54 and the tip end portion 55 are the same, the elastic force acting on the connecting member 15 can be reduced. The plate width dimension of the root portion 54 is larger than the plate width dimension of the tip end portion 55. Thus, compared to the case in which the plate width dimensions of the root portion 54 and the tip end portion 55 are the same, the strength of the root portion 54 can be improved. By gradually narrowing the intermediate portion 56 from the root portion 54 to the tip end portion 55, the stress generated in the intermediate portion 56 can be dispersed.

[0059] In the case of the present embodiment 1, as shown in Figure 6 , the extension portion 43 extends in a straight line from the linking portion 52 to the contact portion 53. Thus, the processing steps of the connecting member 15 can be easily simplified.

[0060] [Other Embodiments] It should be understood that the above-described Embodiment 1 of the present disclosure is illustrative and not restrictive in all aspects. In the case of the above-described Embodiment 1, two stop protrusions are provided with respect to one stop piece. In contrast, according to other embodiments, three or more stop protrusions can be provided with respect to one stop piece. In the case of the above-described Embodiment 1, the stop protrusions are formed by louver processing. In contrast, according to other embodiments, the stop protrusions are not limited to being formed by louver processing. For example, the stop protrusions can be formed by cutting processing, embossing processing, or the like. In the case of the above-described Embodiment 1, the stop protrusions are constituted only by portions protruding in the plate thickness direction of the stop piece. In contrast, according to other embodiments, the stop protrusions can be constituted by a mixture of portions protruding in the plate thickness direction of the stop piece and portions protruding in the plate width direction. In the case of the above-described Embodiment 1, the first stop protrusion protrudes inward in the left-right direction. In addition, the second stop protrusion protrudes outward in the left-right direction. In contrast, according to other embodiments, it can be that the first stop protrusion protrudes outward in the left-right direction and the second stop protrusion protrudes inward in the left-right direction. In addition, it can be that both the first stop protrusion and the second stop protrusion protrude only in either the inward or outward side in the left-right direction. In the case of the above-described Embodiment 1, the extension portions are arranged in three in the left-right direction. In contrast, according to other embodiments, the extension portions can be arranged in two or more or four or more in the left-right direction. Explanation of Reference Signs
