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.

A method for manufacturing a tapered rectangular pipe for a vehicle comprising the steps of forming the tapered rectangular pipe into the rectangular raw pipe by an extrusion forming under any optional irregular thickness condition in a first step. Then the rectangular raw pipe is reduced to form a tapered part to make a tapered, irregular thickness, rectangular pipe member in a second step.

A water pump includes a pump body and a pump cover. An impeller is housed in a pump chamber defined by the pump body and pump cover. The impeller is attached to one end of a hollow pump shaft. The pump shaft is engaged with a driving section at its other end. An intermediate part of the pump shaft is supported by a shaft support section, in the form of a cylindrical section, of the pump body. The shaft support section is longer than a diameter of the pump shaft. The shaft support section is lubricated via an oil groove. One end of the shaft support section is brought into contact with a flange of the pump shaft via a washer. The flange is integrally formed on the pump shaft by a beading process.
