<P>PROBLEM TO BE SOLVED: To prevent partial lowering of the elasticity of a second resin and partial peeling of the second resin in a two-layered molded product wherein force is applied to the second resin. <P>SOLUTION: A protective cap 1 is obtained by providing a seal material 3, of which the elasticity is larger than that of a lid body 2, to the inner surface of the lid body 2. A through-hole 6 is formed to the lid body 2 corresponding to the place overlapped with the seal material 3. When collasping force is applied to the seal material 3 to deform the seal material 3, the through-hole 6 becomes the escape hole of the collapsing force because there is the through- hole 6 on the side opposite to the force applied side to partially absorb the deformation part of the seal material 3. Therefore, the lowering of the elastic force in the vicinity of the force applied part and the peeling of the seal material 3 can be prevented. <P>COPYRIGHT: (C)2004,JPO |
