Abstract
A disc rotor includes a sliding portion, a hat portion, and a connecting unit connecting the sliding portion and the hat portion. The connecting unit includes a washer arranged between the radially inner portion of the sliding portion and the radially outer portion of the hat portion, and a connecting pin having a head portion, having a shaft portion inserted through a first through-hole formed at the sliding portion, the washer and a second through-hole formed at the hat portion in an axial direction of the rotor, and riveted at an end portion of the shaft portion so as to integrally fasten the sliding portion, the washer and the hat portion. A riveted portion of the connecting pin is formed into a taper shape, and an outer circumferential surface of the riveted portion contacts and engages a tapered surface formed at the second through-hole of the hat portion.
