摘要： Even when a cheap magnetic responsive element is used for a magnetic detecting portion, a rotation detector excellent in vibration resistance is provided, a housing 1 being provided with a tubular insertion portion 1a through which an axle 13 is inserted. A rotor 5 is provided with a cylindrical portion 5a through which the insertion portion 1a is inserted and that has a plurality of magnetic poles and rotates synchronously with a front wheel (wheel) 11 fitted to the axle 13. The magnetic detecting portion (rotation detecting portion) 3 detects a change of magnetic poles accompanying the rotation of the cylindrical portion 5a. A spacer (magnetic member) 4 is disposed in the surroundings of the insertion portion 1a of a bottom portion 1g of the housing 1, and holds the rotor 5 at the bottom portion 1g when the cylindrical portion 5a is fitted into the insertion portion 1a.
