Abstract
A sandwiched-molded part for a transmission apparatus has a slide rail body and a rail support body. A chain runs in slidable contact with the slide rail body. The molded part has a first resin forming a surface layer. The first resin has NYLON (66) as a main component. The melt viscosity of the first resin at a temperature of 300° C. is 500 Pa·s to 2000 Pa·s at a shear rate of 1000 s−1. A second resin forms a core layer of the molded part and has a bending strength higher than that of the first resin. The wall thickness of the surface layer of the sliding part of the slide rail body is 1.0 mm or more.
