  • Rotary connector with a steering angle sensor
    Patent number: 9371046
    Abstract: A steering angle sensor (3) includes: a sensor housing (40) that is fixable to a stator (11); idler gears (47) configured to be meshed with a drive gear (30) and rotated by the drive gear (30); a rotatable member (43) configured to be engaged with a sleeve (20) and rotated integrally with the sleeve (20); a detector (34) configured to detect rotation of the rotatable member (43); and a holder (49) configured to hold the detector (34). The sensor housing (40) is opened at its stator (11) side. A second storage space (50) is formed that is enclosed by the sensor housing (40) and the stator (11). The rotatable member (43) is stored in the second storage space (50). The holder (49) is able to hold the detector (34) even in the state where the second storage space (50) is not closed by the stator (11).
