Then, the pair of blade portions 25, 35 of the clips 23, 33 are elastically deformed in the direction of approaching each other, and insertion into the mounting holes 4, 5 is permitted. In the process of the pair of blade portions 25 and 35 entering the mounting holes 4 and 5, the pair of spring portions 22 and 32 abut on the vehicle body panel 1. The pair of blades 25, 35 are inserted into the mounting holes 4, 5 against the spring force of the pair of springs 22, 32, and the contact surfaces 25a, 25b, 35a of the pair of blades 25, 35, When the 35b is removed from the mounting holes 4 and 5, the pair of blade portions 25 and 35 are elastically restored and deformed. As a result, in the first mounting portion 20 and the second mounting portion 30, the pair of spring portions 22a, 22b, 32a, 32b and the pair of blade portions 25, 35 sandwich the vehicle body panel 1 so that each mounting hole 4 is inserted. , 5 is prevented from moving in the insertion / detachment direction (positioned in the insertion / detachment direction). Further, in the first mounting portion 20 and the second mounting portion 30, the pair of locking rib portions 26 and 36 are pressed against the inner peripheral surfaces of the mounting holes 4 and 5 by the elastic return force of the blade portions 25 and 35. By doing so, the movement of the vehicle body panel 1 in each surface direction is prevented (positioned in each surface direction). As described above, the protector 10 is fitted with the vehicle body panel 1 sandwiched between the first mounting portion 20 and the second mounting portion 30. This completes the work of attaching the protector 10.
