ROTATION DETECTOR

摘要

A rotation detector A for detecting rotation of an object (5) fixed to the part (1a) of a housing (1) for inserting an axle S and rotating together with a front wheel (wheel) (10) by means of a magnetic detection element (magnetic detecting means) (3). The object (5) is provided with a cylindrical section (detecting section) (5a) for detecting rotation through the magnetic detecting means (3), and a resilient rotation transmitting section (rotation transmitting section) (5c) for transmitting rotation of the front wheel (10) to the cylindrical section (5a).
