摘要：
A support bracket structure is realized, in which the support bracket is made using a metal plate and sufficient strength and rigidity thereof can be maintained, and the production costs thereof can be kept sufficiently low by improving the yield of material. A support bracket 14a for supporting the front end section of a steering column 6a by way of a housing 9a of an electric power-steering apparatus is manufactured by using a press to punch out and bend a metal plate. By devising the dimensions and bending direction of each part, the yield of material is improved, while at the same time the height dimensions of the first side plate section 19 and the second side plate section 20 required for maintaining the support rigidity under a heavy load is maintained.
