Document Type and Number:
WIPO Patent Application WO/2018/079471
Kind Code:
A1
Abstract:
Provided is an angle detecting device with which it is possible for an electrical circuit board to be secured without performing resin molding, which is simple to manufacture, and with which assembly time and manufacturing costs can be reduced. A magnetic encoder (8) having a magnetic track in which N poles and S poles are arranged alternately is secured to a rotating wheel (2) of a rolling bearing (7). An electrical circuit board (14) on which a magnetic sensor (13) is mounted is secured to a fixed wheel (2) of the rolling bearing (7) in such a way that the magnetic sensor (13) is disposed in a position facing a magnetic track member (10) of the magnetic encoder (8) across a gap. The electrical circuit board (14) is secured by means of a fixture such as screws or another threaded member, or by means of an adhesive, to a sensor housing (12) supported integrally with the fixed wheel (2).
