摘要：
A disk brake includes a caliper body having a cylinder portion 25 with a cylindrical shape. The cylinder portion 25 has a bore 30 with a bottom 34 formed by integrally joining together an opening peripheral edge 98 at the bottom side of the cylinder portion 25 and a bottom cover member 92 to be fitted to the opening peripheral edge 98 through friction stir welding. The bottom cover member 92 has a disk shape and is friction-stir-welded along the outer periphery thereof. The terminating point of the friction stir welding is within the boundaries of the bottom cover member 92.
