<p>A body portion (22) and an attachment portion (23), which are formed of resins having different properties, are united with each other without the use of any large-scale mechanism to form a door trim (21). The door trim (21) comprises the body portion (22) of resin constituting a front surface of the door trim (21) of a vehicle and the attachment portion (23), which is formed of a different resin from that of the body portion (22), of which a lower end is integral with the body portion (22) through a flexible hinge portion (25), of which an upper end is engaged with the body portion (22) through a pawl (26) and a projection (27), and which is provided with ribs (24) constituting a rear surface of the door trim (21) and functioning to absorb shocks. The door trim (21) is formed by integrally forming the body portion (22) and the attachment portion (23) made from resins of different properties while constantly maintaining a positional relationship therebetween in a predetermined state without the use of any large-scale mechanism.</p> |
