Abstract
A resin casing of a box-like configuration has side walls, a bottom wall and a plurality of partition walls. Each partition wall has two opposite end portions tapered, at which the partition wall is integrally formed with the side wall. Thus, the cooling speed is made constant at every portion in the resin casing to avoid shrinkage marks and unwanted raised lines.
