And the claw portions 72 protruding from the rectangular holes 58 interfere with each other. Therefore, the claw portion 72 is pressed according to the insertion operation,
The stopper member 62 is guided by the arc groove 60 and is moved in the base direction of the cylindrical shaft portion 54.

Here, when the tip of the leg 68 of the stopper member 62 contacts the head 50, the movement of the stopper member 62 is stopped. If the insertion of the cylindrical shaft portion 54 is further continued in this state, the claw portion 72 pressed against the peripheral edge of the circular hole 26 is elastically deformed and enters the rectangular hole 58. This allows
Insertion of the cylindrical shaft portion 54 is performed smoothly.

As a result, even if the cylindrical shaft portion 54 tries to escape from the circular hole 26, the claw portion 72 interferes with the peripheral edge of the circular hole 26, and its movement is limited to the movable range of the stopper member 62 in the circular arc groove 60. Then, it can be held in a temporarily fixed state.

Next, the deck trim 16 is positioned with respect to the rear floor panel 14. By this positioning, the male screw 56 of the cylindrical shaft portion 54 and the female screw 38 of the receiving member 30 attached to the rear floor panel 14 become coaxial.
At this time, since the screw grommet 48 can rotate and swing freely, the male screw 56 can be easily aligned with the female screw 38.

As described above, in this embodiment, since the screw grommet 48 is prevented from dropping out of the circular hole 26 of the deck trim 16 by the claw 72 of the stopper member 62, the deck trim 16 and the rear floor panel 14
The workability at the time of connection with the structure is improved. In addition, deck trim 1
When the 6 is removed from the rear floor panel 14,
The screw grommet 48 does not fall out of the circular hole 26 of the deck trim 16 even if the screwing between the screw and the female screw 38 is released, so that the screw grommet 48 is not lost.
