<p>A rotation detector capable of providing an excellent vibrationproof performance even if an inexpensive magnetic reaction element is used in a magnetic detection part, comprising a housing (1) having a tubular insert part (1a) for inserting an axle (13) therethrough, a rotating body (5) allowing the insert part (1a) to be inserted therethrough and having a cylindrical part (5a) with a plurality of magnetic poles and rotated in synchronous with front wheels (wheels) (11) installed on the axle (13), a magnetic detection part (rotation detection part) (3) for detecting a variation in polarity according to the rotation of the cylindrical part (5a), and a spacer (magnetic member) (4) installed at the bottom part (1g) of the housing (1) around the insert part (1a) and stopping the rotating body (5) at the bottom part (1g) when the cylindrical part (5a) is fitted to the insert part (1a).</p> |
