Rotor and motor

The purpose of the present invention is to provide a rotor and a motor with which it is possible to provide an appropriate amount of adhesive between the inner peripheral surface of a rotor magnet anda bush for securing the rotor magnet to a rotary shaft. In the motor 1, the rotor 10 has a cylindrical rotor magnet 11 disposed coaxially around a rotary shaft 12, and a first bush 14 provided with acenter hole 140 into which the rotary shaft 12 has been pressed. A first end surface 141 of the first bush 14 has formed thereon an outflow prevention wall 147 for preventing the outflow of an adhesive 18, the outflow prevention wall 147 being formed by a radially outward-facing peripheral surface 145a of a wall formation part 145, which comprises a rib-shaped convex part and which is formed at aposition set apart radially inward from an outer peripheral edge 141a of the first end surface 141. The first bush 14 is a metal plate, and the wall formation part 145 is formed by press working. A second bush 15 is substantia
