  FIG. 7 is a cross-sectional view taken along the line AA of FIG. 1 in which the base member 2 and the cover 3 are integrated as a protector 1, and FIG. 8 is a cross-sectional view taken along the line BB of FIG. The stud housing part 7 of the base member 2 is a hollow cylindrical body having an opening 8 in the upper part and having a substantially square shape (see FIG. 3) in plan view. The inside of the stud housing portion 7 is a housing portion for the stud bolt 21 and the bottom 18 is sealed.

  Inside the stud storage part 7, two engaging parts 9 protrude diagonally downward from the main body wall part 19 and are provided at two symmetrical positions. Further, an engaging projection 9t is formed at the tip of the engaging portion 9 corresponding to the groove shape of the stud bolt 21, and the engaging portion 9 is made of resin and can be deformed by bending. Further, the engaging portion 9 is formed as a long plate-like body as shown in FIG. 8, and an engaging protrusion 9t is formed along the longitudinal direction. Two engaging portions 9 are provided at symmetrical positions, that is, one set is provided, but two sets (four) or more may be provided. By forming the engaging portions 9 as two or more sets of multiple stages, the engaging force in the engaging portions 9 can be increased, and the pull-out preventing force of the stud bolt 21 can be increased.

  A guide portion 14 of the cover 3 is disposed so as to contact the opening 8 of the stud housing portion 7. The guide portion 14 is formed as a through hole so that the guide surface 16 is tapered.

  The insertion of the stud bolt 21 will be described with reference to FIG. The stud bolt 21 is provided in a protruding state with a fixing means such as welding at the end face of the head with respect to the base material of the vehicle body 32. As shown in FIG. 9A, the guide portion 14 is applied to the stud bolt 21 erected on the vehicle body 32, and the protector 1 is pushed in as it is, so that the tip end portion of the stud bolt 21 slides on the guide surface 16. The bolt 21 is pushed into the stud housing part 13 of the protector 1. The guide portion 14 covering the stud housing portion 13 is tapered so that one end of the guide surface 16 forms a first opening 23 and the other end forms a second opening 24 having a smaller area than the first opening 23. The second opening 24 has a smaller area than the opening 25 of the stud storage portion 7. Further, the area of the first opening 23 of the guide portion 14 is formed larger than the area of the opening 25 of the stud storage portion 14. For this reason, when the protector 1 is pushed into the stud bolt 21, after contacting the guide surface 16 of the guide portion 14, the protector 1 is guided by the guide surface 16, and the stud bolt 21 is engaged from the opening 25 of the stud housing portion 7.

  Since the guide portion 14 is formed separately from the stud storage portion 7, even if the stud bolt 21 erected on the vehicle body 32 is difficult to see from the operator, the stud bolt is formed on the guide surface 16 by groping. 21, and the stud bolt 21 abuts on the guide surface 16, whereby the stud bolt 21 is guided to the stud housing portion 14 by the guide surface 16.

  Since the engaging portion 9 is formed as a long plate-like body, the mounting pitch error of the stud bolt 21 can be shifted and dealt with in the longitudinal direction.

  As shown in FIG. 10, a gap 28 may be formed between the base member 2 and the cover 3 when the stud bolt 21 is inserted. That is, the base member 2 and the cover 3 do not need to be completely fixed to each other before the stud bolt 21 is inserted. If the base member 2 and the cover 3 are temporarily fixed, the stud bolt 21 is inserted into the stud housing portion 13. By screwing the base member 2 with a plurality of screw holes (not shown), the stud bolt 21, the cover 3, and the base member 2 are fixed as shown in FIG. 9B. By forming the gap, the cover 3 and the base member 2 can be moved relative to each other, and the work of attaching the protector 1 to an appropriate position can be facilitated.

  By configuring the stud storage part 7 and the guide part 14 from different materials, the area of the first opening 23 is increased and the area of the second opening 24 is decreased as shown in FIG. You can also. In this case, the area of the guide surface 16 is further increased, and it becomes easier for the operator to contact the stud bolt 21 with the guide surface 16 by groping. That is, by configuring the stud storage portion 7 and the guide portion 14 from different materials, the inclination of the guide surface 16 can be designed without being affected by the inclination of the engagement portion 9, and the second opening 24 can be made small. By doing so, it is possible to prevent the front end portion of the stud bolt 21 from coming into contact with the upper surface 9s of the engaging portion 9 and damaging the engaging portion 9.

  As described above, the stud storage portion 7 and the guide portion 14 are made of different materials, so that the guide portion 14 can be formed larger and the size and shape of the guide surface 16 of the guide portion 14 are engaged. It can be formed without being restricted by the portion 9. As a result, the operator can easily engage the engaging portion 9 with the stud bolt 21 erected at a position where it is difficult to see. In addition, in the Example, although the stud bolt 21 erected on the vehicle body 32 was demonstrated as an example, it is not restricted to the vehicle body 32 that the stud bolt is erected.
