Abstract
A pin connection structure is used in a floating type brake disc assembly. The assembly is made up of a hub, and an annular disc which is concentrically disposed around the hub with a clearance therebetween. The hub and the disc have plural sets of semicircular connecting dents opening toward the clearance to thereby form respective inserting holes. A hollow pin is inserted into each of the inserting holes with a washer fitted on that one end of the hollow pin which is subsequently caulked radially outward for fixing the washer in position. The hollow pin is made of a metal having a surface-treated layer, and the caulked end of the hollow pin is formed into a convex shape in at least part of the end portion.
