And the lower end portion 72 (corresponding to the second end portion) are connected to the first nut portion 20 and the second nut portion 30 through the second weakened portion 60, respectively, and are positioned with the cross-shaped center O interposed therebetween. A direction (a front wall 3B1 of the reinforcement 3) in which one end portion 73 (corresponding to the third end portion) and the other end portion 74 (corresponding to the fourth end portion) of the connecting body 70 in the width direction are separated from the same plane as the fixing portion 10. And bent to the bent portion 41K of one connecting portion 41 and the bent portion 42K of the other connecting portion 42 in an easily deformable state. Gaps 37 (spaces) are formed between the first flat plate portion 21 and the second connecting body 70 and between the second flat plate portion 31 and the second connecting body 70, respectively. 2 The relative movement of the flat plate portion 31 is enabled. That is, in each flat plate portion 21, 31, the first fragile portion 50 is disposed on both sides, and the second fragile portion 60 is disposed at an end portion in a direction perpendicular to the arrangement direction of the first fragile portions 50. With this arrangement, the flat plate portions 21 and 31 can prevent rotation about the alignment direction of the first fragile portions 50 during conveyance.

As shown in FIG. 1, the first and second flat plate portions 21 and 31, the first and second weld fixing portions 11 and 12, a pair of connecting portions 41 and 42, a second connecting body 70, and the first and second portions. The fragile portions 50, 60 are integrally formed by pressing a single metal plate. By this pressing, the first and second flat plate portions 21, 31 and the first and second weld fixing portions 11, 12 are formed. On the other hand, the pair of connecting portions 41, 42 and the first and second weakened portions 50, 60 are bent to the opposite side (the vehicle rear side) of the front wall 3B1 of the reinforcement 3 to rise at a right angle. The retainer 100 is point-symmetrically formed with respect to the cross-shaped center O of the two connected body 70.
When the retainer 100 is viewed from the outer side in the width direction of the retainer 100 (viewed from the vehicle width direction), the connecting portions 41, 42, the first weld fixing portion 11, the first flat plate portion 21, the second flat plate portion 31, A gap 38 (space) is formed between the second welding fixing portion 12 and the second welding fixing portion 12. That is, in the assembled state of the retainer 100 with respect to the front wall 3B1 of the reinforcement 3, the gap 38 is formed between the connecting portions 41 and 42 and the back surface 3U of the front wall 3B1 of the reinforcement 3. Similarly, in the assembled state, a gap 35 (space) is formed between the second connector 70 and the back surface 3U of the front wall 3B1 of the reinforcement 3 (see FIG. 2B).
As a result, the contact area between the retainer 100 and the front wall 3B1 of the reinforcement 3 is reduced, and the retainer 100 is assembled to the reinforcement 3 (the first welding fixing portion 11 and the second welding fixing portion 12 are connected to the front of the reinforcement 3). It is possible to make it easier for the coating liquid to enter the inner side in the width direction of the retainer 100 through the gaps 38 and 35 at the time of coating (after being fixed to the back surface 3U of the wall 3B1 by welding). Accordingly, it is possible to prevent rust from being generated on the pair of connecting portions 41, 42 and the back surface 3U of the front wall 3B1 of the reinforcement 3 facing the pair of connecting portions 41, 42, and the pair of connecting portions 41, 42 and the front wall 3B1 of the reinforcement 3 can be prevented from colliding with each other, and the generation of abnormal noise due to the collision can be prevented.
As described above, in the retainer 100 of the present invention, the gaps 36, 37, and 38 are provided, and the above-described effects can be obtained by minimizing the contact area with the back surface 3U of the front wall 3B1 of the reinforcement 3. I can do it.

  The width of the first fragile portion 50 in the vertical direction Z, which is the direction in which the first weld fixing portion 11, the first flat plate portion 21, the second flat plate portion 31, and the second weld fixing portion 12 are arranged, is set to the first nut 22 and the second. The width of the second fragile portion 60 in the vehicle width direction W (corresponding to the second direction) perpendicular to the vertical direction Z is set to be smaller than the inner diameter of the female thread portion 33 of the nut 32 and the width of the first nut 22 and the second nut 32 is set. It is set smaller than the inner diameter of the female thread portion 33.

The retainer 100 having the above structure is manufactured by the following procedures (1) to (4).
[Manufacturing Method of Retainer 100]
(1) A single metal plate is pressed (punching) to form a perforated developed intermediate retainer 89 (see a two-dot chain line in FIG. 2A).
(2) The unfolded retainer intermediate body 89 is embossed so that the bent portions 41K and 42K of the second connecting body 70 and the pair of connecting portions 41 and 42 are located more than the surfaces of the fixed portion 10 and the flat plate portions 21 and 31. Make it rise. In addition, this process can also be performed simultaneously with the process of (1) by the press process of (1).
The deformation of the retainer 100 can be absorbed by the embossed second connecting body 70 and the bent portions 41K and 42K of the pair of connecting portions 41 and 42. As a result, the portion of the retainer that is not in contact with the vehicle body can be prevented from coming into contact with the vehicle body, and problems such as the generation of abnormal noise can be prevented.
(3) The side corresponding to the opposite side to the back surface 3U of the front wall 3B1 of the reinforcement 3 by bending the pair of connecting portions 41 and 42 with respect to the surfaces of the fixed portion 10 and the flat plate portions 21 and 31 by pressing. Stand up on the side corresponding to the rear of the vehicle.
(4) The first nut 22 is fixed to the first flat plate portion 21 by welding, and the second nut 32 is fixed to the second flat plate portion 31 by welding.
In the step of welding and fixing the first weld fixing portion 11 and the second weld fixing portion 12 of the retainer 100 to the back surface 3U of the front wall 3B1 of the reinforcement 3, the second connecting body 70 can be clamped as a clamp seat surface. In this case, some deformation of the retainer 100 can be absorbed by the embossed second connecting body 70 and the bent portions 41K and 42K of the pair of connecting portions 41 and 42. As a result, the workability of the welding operation can be improved and the productivity can be improved by eliminating the problem of misalignment due to slipping or the like when the retainer 100 is set with respect to the reinforcement 3.
