In the present embodiment, as shown in FIG. 3, an inclined portion 36 having a downward slope toward the outer peripheral side is formed on the upper surface of the face plate 34 of the hole plug 14. Therefore, when the hole plug 14 is placed in the mounting hole 12 of the body panel 10, the inclined portion 36 of the face plate 34 is inclined downward from above with respect to the upper surface (mounting surface) of the body panel 10. .

  For this reason, when the inclined portion 36 of the face plate 34 is pressed in the direction of insertion into the attachment hole 12 with the hole plug 14 placed in the attachment hole 12 of the body panel 10, the inclined portion 36 of the face plate 34 is pressed. The portion of the hole plug 14 on the inclined portion 36 side is inserted into the mounting hole 12 from an oblique direction (the direction of arrow P in FIG. 7). Thereafter, other portions of the hole plug 14 are also inserted into the mounting hole 12, and the engaging claws 20 that are formed to protrude from the outer wall surface of the outer peripheral wall portion 18 are engaged with the peripheral edge portion 12 </ b> B of the mounting hole 12 on the lower surface of the body panel 10.

Therefore, the assembly performance of the hole plug 14 to the mounting hole 12 can be improved.

  In the present embodiment, the inclined portion 36 is formed within the range of the thickness M5 of the face plate 34. For this reason, the inclination angle θ <b> 1 of the inclined portion 36 can be adjusted within the range of the thickness M <b> 5 of the face plate 34. As a result, by adjusting the inclination angle θ1 of the inclined portion 36, the insertion force of the hole plug 14 into the mounting hole 12 can be effectively reduced.

  In the present embodiment, the lowermost portion 36 </ b> A in the inclined portion 36 is the outer peripheral edge portion of the face plate 34. For this reason, the inclination part 36 can be formed in a wide range between the boundary line K1 by making the outer peripheral edge part of the face plate 34 into an end point. As a result, the insertion force of the hole plug 14 into the mounting hole 12 can be effectively reduced.
