Claims

[Scope of utility model registration request]

(1) In a rotor of a magnet generator in which a plurality of magnets are arranged at intervals on the inner periphery of a bowl-shaped yoke, the rotor is curved in the width direction with a curvature larger than the curvature of the inner diameter of the yoke. Each of the magnets is housed in a plurality of approximately frame-shaped cases with pole pieces arranged on the inner surface,
These cases are arranged in an annular shape and press-fitted into the yoke, and each case is elastically deformed in the direction of decreasing curvature by mutually pressing adjacent cases, and each magnet is pressed against the inner peripheral surface of the yoke by this elastic force. A rotor of a magnet generator characterized by being fixed.

(2) A rotor for a magnet generator according to claim 1, wherein the case is tapered in the height direction.

(3) The bottom wall of the yoke has a closure hole into which a protrusion formed on the bottom surface of the center of the floor member of the case is fitted, and the closure hole has a radial length of the yoke that is the radius of the protrusion. A rotor for a magnet generator according to claim 1, characterized in that the rotor is longer than the length in the direction.
