To provide a synthetic resin molded product constituted so as not only to reduce the weight of a main body having an inner space part but also to increase the mechanical strength thereof and having an outer surface excellent in appearance.
The synthetic resin molded product is constituted by integrally forming a rib 41 on the inner surface of the inner space part 40 in a grasping part main body 4A made of a synthetic resin having the inner space part 40 and a groove line 42 is formed to the region corresponding to the rib 41 in the outer surface of the grasping part main body 4A in parallel to the rib 41. The mechanical strength of the grasping part main body 4A is increased by the rib 41 and, if the rib is formed up to the vicinity of the undersurface of the grasping part main body 4A, the gripping feeling of a grasping part is enhanced. If the thickness of the rib is increased, a sink is formed on the upper surface of the grasping part along the rib but the sink is concealed by the groove line 42 while the appearance of the synthetic molded product is enhanced by the groove line 42.
