Abstract
A fixing unit has a crown-shaped resilient member comprising an annular cylindrical member and a flange extending integrally from an upper end of the annular cylindrical member. The annular cylindrical member has a first tooth, and the flange has a second curved portion. The first tooth engages in an annular groove defined in the outer circumferential surface of an upper end of the housing, and the second curved portion presses a step on the outer circumferential surface of a lower portion of a sensor case, for fixing the sensor case and the housing to each other. A first support has a first flange supported on a step on an inner wall surface of the housing, and a second support has a first flange supported on another step on the inner wall surface of the housing. A coil is sandwiched and held between the first and second supports. The sensor case is directly held against the first support. The lower surface of the sensor case and the upper end of the housing are spaced a given distance from each other. A crown-shaped resilient member is installed on joined portions of the sensor case and the housing to hold the sensor case, the housing, the first and second supports, and the coil securely together.
