The roof molding 50 is prevented from being lifted by pressing against the inner side surface.

  The terminal portion 58 is provided on the molding body 51 for reasons such as improving the appearance of the terminal of the roof molding 50 or responding to the fact that the roof molding groove R3 is shallow in the longitudinal direction of the vehicle body. The end is formed by injection molding. At the end portion of the molding body 51 where the terminal portion 58 is formed, the lower portion of the leg portion 54 is partly cut off, and the terminal portion 58 is injection-molded including the cut trace portion. The terminal 58 is provided with engaging claws 59 and 59 as terminal mounting engaging portions on both sides (left side and right side) on the lower end side (back side).

The terminal portion 58 of the roof molding 50 is fixed by engaging with the engaging claw pieces 62 and 62 of the clip 60 as means.

  On the other hand, as shown in the FF cross-sectional view of FIG. 9, the tip of the lip 55, 55 formed on the leg portion 54 is pressed against the side surface in the roof molding mounting groove R3. Then, it is fixed by suppressing the floating of the roof molding 50. The roof molding mounting groove R3 is formed on the center panel R1 and the side panel R2 so that the width on the opening side (entrance side) (that is, the interval between the opposing side surfaces) is narrower than the bottom side (back side) inside. Since the edge is bent, the lips 55 and 55 that are in pressure contact with the side surface in the roof molding mounting groove R3 are not easily displaced upward, and can be prevented from being lifted at an intermediate portion between both ends of the roof molding 50.

  However, depending on the material and processing conditions of the center panel R1 and the side panel R2 of the roof R, the roof molding mounting groove R3 cannot be made narrower on the opening side (entrance side) than on the inner bottom side (back side). In some cases, the degree of narrowing may be reduced. In that case, as shown by a chain line in FIG. 11, the tip side of the lips 55, 55 formed on the leg portion 54 is fixed by being pressed against the opposite side surfaces R3a, R3a in the roof molding mounting groove R3. There is a possibility that an intermediate portion between both ends of the roof molding 50 is lifted or wavy due to a temperature change of the roof molding, expansion / contraction of the roof molding 50, vibration of the vehicle body, or the like. In particular, the lip 55, 55 that is in pressure contact with the opposite side surfaces R3a, R3a in the roof molding mounting groove R3 has a restoring force that tries to return to the state before the insertion into the roof molding mounting groove R3. Since a force to move the roof molding 50 toward the opening side of the roof molding mounting groove R3 acts, the intermediate portion where the lips 55 and 55 are formed is easily lifted.
