PURPOSE:To enable a main body made of resin to be satisfactorily bonded with the surface of a metallic core bar as well as to make the aforesaid resin capable of preventing the occurrence of sink marks over the surface of the main body while being of desired characteristics with cost lowered. CONSTITUTION:This invention is concerned with the provision of a molding furnished with a metallic core bar 5, and with a main body 2 made of resin which is extruded into a bar in such a way that the surface of the core bar 5 is covered, the main body 2 is made of desired synthetic resin, and an aggregate 6 is provided in the inside of the main body 2 which is bonded with the surface of the core bar 5 while the main body 2 is furthermore bonded with the core bar 5 in such a way that both of them can not be relatively moved. The aggregate 6 is made of synthetic resin which is excellent in bonding reactivity against the surface of the core bar 5. |
