PROBLEM TO BE SOLVED: To reduce the cost of a bracket by forming the main part by extrusion molding, and easily integrating an attaching part with a bulging shape bulged from the main part to an extrusion direction therewith. SOLUTION: An aluminum alloy or the like is subjected to lengthy extrusion molding, and is cut so as to be a standard length to form the main part 6 of a bracket 2. The main part 6 is provided with a ring-shaped part 7, and the inside thereof is provided with a bush 3. Further, an attaching leg 8 and a projecting part 10 for connection are provided integrally with the main part 6. The projecting part 10 for connection is provided with a through hole 11, and a reinforcing member 12 is inserted therein so as to be longer than the cut width. The projecting part 10 for connection and the reinforcing member 12 are cast-in in this state, so that an attaching part 13 with a bulging shape longer than the cut width, and also, bulged to the extrusion direction of the main part 6 is integrally formed.
