摘要： A magneto device for generating signals comprises a rotor including a permanent magnet and a pole piece which are secured to a rotary body, and a stator including a stationary pole piece and a signal output coil. Formed in the outer periphery of the rotary body is a recess in which the permanent magnet and the pole piece are inserted in this order. A cylindrical key member made of a non-magnetic metal is inserted in an annular space between the wall of the recess and the permanent magnet and pole piece. The key member is plastically deformed by pressing to secure the permanent magnet and pole piece to the rotary body.
