EPDM (ethylene-
Soft P blended with propylene-diene copolymer rubber)
P-based material is used. The soft PP material is EPD
M softens the side garnish and reduces the rigidity of the side garnish. Therefore, as shown in FIG. 5, a metal plate 21 is attached to the back surface of the side garnish 20 to supplement the rigidity, or the thickness of the side garnish 20 is increased to 4.5 mm, for example.
It was formed as thick as ~6 mm.

ａのみが充填される。As shown in FIG. 2, a sufficient amount of soft PP material 3a to form the skin layer 3 of the side garnish 1 is injected into the cavity 7 from the gate 6. Next, as shown in FIG. 3, the hard PP material 2a forming the core layer 2 is similarly injected into the cavity 7 from the gate 6. At this time, the soft PP material 3a that was injected first is pushed out by the hard PP material 2a that was injected later, and is pressed against the inner wall surface of the cavity 7. At this time, if the hard PP material 2a is further injected from the gate 6 into the cavity 7, the state shown in FIG. 4 will be obtained. That is, inside the cavity 7, the hard PP material 2a is completely covered with the soft PP material 3a. Then, a soft PP material 3 is used for the lip portion L having a small thickness width.
Only a is filled.

Ru. As detailed above, the side garnish 1 of this embodiment
According to the above, sufficient rigidity can be maintained by the core layer 2 formed of the hard PP material 2a without using the metal plate 21 as in the conventional case, and the total weight of the side garnish 1 is approximately less than that of the conventional side garnish. It is about 50% lighter.

る。[0013] When forming the side garnish 1, the sandwich molding method is used to form soft and hard PP in one step.
Since two types of materials 3a and 2a can be injected, the number of work steps can be reduced and manufacturing costs can be reduced. Furthermore, the wall thickness of this side garnish 1 is, for example, 3 to 3.
Since it can be formed as thin as 4.5 mm, the difference in level between the body and the side garnish 1 can be reduced, and the appearance of the automobile can be improved. Furthermore, skin layer 3
uses a soft PP-based material with excellent paint adhesion, so the surface of the skin layer 3 has good paint adhesion, so acrylic paints, urethane paints, etc. can be easily applied. It is possible to form a coating film with good durability.
