<P>PROBLEM TO BE SOLVED: To improve appearance by uniformly spreading a skin sheet on a surface of a blow molding and preventing exposure of the blow molding from the skin sheet, in a stuck blow molding obtained by sticking the skin sheet on one wall surface of a double wall blow molding where a reinforcing rib reaching another wall from one wall is formed. <P>SOLUTION: The reinforcing rib is a recessed rib 15 having a groove inside and the recessed rib 15 is composed of a first rib 17 and a second rib 18 which are alternately formed along a length direction. A top end of the first rib 17 is welded to an inside of the wall 14. The skin sheet 12 enters the inside of the grooves of the recessed rib 15 (a groove 23 of the first rib 17 and a groove 27 of the second rib 18), and is stuck to both walls of the groove. In the skin sheet 12, at a place of the groove 23 of the first rib 17, a slit 32 is formed along the length direction of the groove 23. At a place of the groove 27 of the second rib 18, the skin sheet 12 has no slit 29 and is continuous. <P>COPYRIGHT: (C)2013,JPO&INPIT |
