On the other hand, the end surface 22c-1 on the side of the cutout portion 22a of the wide extending portion 22c is substantially flush with the upper surface of the facing portion 4b that functions as a flange.

  Similarly, the opposing end portion 23 is provided with extension portions 23b and 23c with the notch portion 23a interposed therebetween, and the upper and lower end surfaces of the narrow extension portion 23b are tightly located inside (upper and lower surfaces) of the cylindrical portion 10c. The first reinforcing portion 13 is further reinforced by fitting. On the other hand, the end surface 23c-1 on the cutout portion 23a side of the wide extending portion 23c is substantially flush with the upper surface of the facing portion 5b that functions as a flange.

  In the case of the suspension bolt support 1 of the present embodiment configured as described above, a U-shaped reinforcing member 20 is inserted into the space 10a of the suspension bolt support main body 10, and two sets of mounting holes 22d. Etc., bolts and nuts (not shown) are attached to the reinforcing bolts 20 to fix the reinforcing member 20 to the suspension bolt support body 10, and the opening 10 b connected to the space 10 a is closed by the rectangular intermediate portion 21 of the reinforcing member 20. Accordingly, four sides (2j, 3j, 4j, 5j) around the opening 10a of the suspension bolt support body 10 are arranged on the four outer sides of the intermediate portion 21 (both ends 21a and 21b in the width direction and both ends 21c in the length direction). , 21d) can be at least partially brought into contact with each other, and in addition, the opposing ends of the reinforcing member 20 are arranged on the four sides (2j, 3j, 4j, 5j) around the opening 10a of the suspension bolt support body 10. The two sides (ends) 22f and 22g of the portion 22, the two sides (ends) 23f and 23g of the opposing end 23, and the outer surfaces of the opposing ends 22 and 23 in the width direction are at least partially in contact with each other. It becomes possible to make it. Thereby, a deformation | transformation of the suspension bolt support tool main body 10 is suppressed. In addition, the opposing end portions 22 and 23 are bolted to the first opposing surfaces 4 and 5 via two sets of mounting holes 22d and 22e, so that the suspension bolt support main body 10 is deformed. Will be suppressed. Therefore, even if it is the 1st, 2nd attachment state mentioned above, the fall of durable strength can be prevented, and it becomes possible to use a cheaper material or a thinner material in connection with this, and cost. Inexpensive can be achieved.

  In the present embodiment, as described above, the end surface 22c-1 on the side of the cutout portion 22a of the wide extension portion 22c is substantially flush with the upper surface (in FIG. 1) of the facing portion 4b. Further, since the end surface 23c-1 on the side of the notch 23a of the wide extending portion 23c is substantially flush with the upper surface (in FIG. 1) of the facing portion 5b, the facing portions 4b and 5b are formed as shown in FIG. In the second attachment state in which the suspension bolt body 10 is attached to the attachment portion 110 in a state of being disposed on the upper side of the horizontal attachment portion 110, it is possible to distribute the stress applied to the suspension bolt support tool body 10 to the reinforcing member 20, Deformation of the suspension bolt support body 10 can be suppressed to prevent a decrease in durability.

  Furthermore, since the narrow extension portions 22b and 23b of the suspension bolt support body 10 are fitted into the cylindrical portion 10c, the first reinforcement portion 13 is further reinforced, and this also causes the suspension bolt The deformation of the support body 10 can be suppressed to prevent the durability from being lowered.

  In addition, since the third reinforcing portion 11 is formed in a state of being curved in the thickness direction at a location closer to the opening 10b than the notches 4a and 5a, the deformation of the suspension bolt support body 10 is suppressed and durability strength is increased. A decrease can be prevented. In particular, it is effective in the case of the first mounting state in which the facing portions 4c and 5c are arranged above the horizontal mounted portion 110 as shown in FIG. And since this 3rd reinforcement part 11 is curved and formed in the thickness direction, it can be formed simultaneously when producing the metal plate of a predetermined shape by stamping.

  Moreover, since the 2nd reinforcement part 12 is formed in the state curved in the thickness direction in each of the facing parts 4b and 5b, it can suppress the deformation | transformation of the suspension bolt support tool main body 10, and can prevent the fall of durable strength. it can. In particular, the second mounting state shown in FIG. 6 is effective, and as shown in FIG. 9B, a second deformation state in which a gap between the facing portion (flange) 104b and the facing portion (flange) 105b opens. It is prevented from becoming. And since this 2nd reinforcement part 12 is also curved and formed in the thickness direction, it can be formed simultaneously when producing the metal plate of a predetermined shape by stamping.

  In the present embodiment, the facing portions 4c and 5c of the first reinforcing portion 13 are arranged on the second facing surface 2 located on the opposite side to the notches 4a and 5a with the first reinforcing portion 13 interposed therebetween. A second screw hole 4g similar to the screw hole 2a for mounting the provided support fixture fixing bolt 6 is separately formed, and the same support fixture fixing bolt 6 is formed in the screw hole 2a and the second screw hole 4g. Is attached, the fourth reinforcing portion is configured by the second screw hole 4g and the support fixing bolt 6 attached to the second screw hole 4g. That is, since the bolt 6 used when attaching the suspension bolt support 1 to the attached portion 110 is supported by the two screw holes 2a and 4g, the bolt 6 receives a force in its radial direction. However, the bolt 6 can be prevented from tilting, and the second screw hole 4g and the bolt 6 attached thereto function as a fourth reinforcing portion.

  In the above-described embodiment, the reinforcing member 20 is attached to the suspension bolt support body 10 including the first reinforcing portion 13, the second reinforcing portion 12, the third reinforcing portion 11, and the fourth reinforcing portions 4 g and 6.
