Since the introduction hole 14 is not formed by cutting out from the end of the pin engaging portion 11, the rigidity of the pin engaging portion 11 is improved. Since the diameter D1 of the engagement hole 13 is larger than the diameter of the shaft portion 7, a predetermined play gap S1 is formed between the shaft portion 7 and the edge of the engagement hole 13. This play gap S
1 is formed in the entire circumferential direction of the shaft portion 7 including the width direction and the front-rear direction since the engagement hole 13 is substantially circular.

Although a step 16 having a slight depth is formed above the engagement hole 13, the step 16 does not form the engagement hole 13. Accordingly, the depth D2 of the engagement hole 13 is slightly smaller than the length of the shaft portion 7, and a predetermined play gap S2 in the vertical direction is formed between the step portion 16 and the head portion 8. A pair of front and rear protrusions 17 are formed at the vehicle outer end of the pin engaging portion 11, and the tips of the protrusions 17 are in contact with (or close to) the side surfaces of the groove 3. Has become. Further, a slope 18 for avoiding interference with the ceiling 4 is formed at the inside corner of the pin engaging portion 11.

The reaction force of the lip 24 automatically centers the molding 10 at the width center position of the groove 3. The appearance of the mall 10 in the groove 3 is improved. As described above, since the clip 9 is attached with the play gaps S1 and S2 in the width direction, the degree of freedom in modeling and the three-dimensional shape followability are also improved.

Furthermore, since the engaging hole 13 is substantially circular and the clip 9 also has a play gap S1 in the longitudinal direction, the mounting position of the clip 9 in the longitudinal direction can be easily adjusted.

The rear end 27 of the molding 10 having been thus centered in the width direction and adjusted in the front-rear direction is fixed by the end cap 28. That is, the rear end 27 of the molding 10 is inserted into the cavity 30 of the end cap 28, and the unevenness 32 formed on the engagement piece 31 in the cavity 30 is engaged with the cut-and-raised portion 29 of the molding 10. Thus, even if there is some variation in the front and rear positions of the molding 10, the end cap 28 can fix the front and rear positions in a state where the variations are absorbed. The elastic engagement force between the cut-and-raised portion 29 and the engagement piece 31 is very small, and does not affect the centering function of the clip 9 and the molding 10.

The molding 10 and the clip 9 finally attached as described above are connected to the lips 2 at both ends in the width direction.
4 is in contact with the side surface of the groove 3, the bridging rib 22 is located directly above the head 8, and the downward lips 25 and 26 are in contact with the bottom surface of the groove 3. Accordingly, the state in the mall 10 is stabilized, and the mall 10 does not fall down.

The plane shape of the engagement hole 13 is only required to have a play clearance S1 at least in the width direction, and need not be circular. Also, the introduction hole 14 is not formed in the pin engagement portion 11,
A notch for introduction from the end of the pin engaging portion 11 to the engaging hole 13 may be formed.
