摘要： A torque-detecting device having sufficient mechanical strength, capable of performing accurate torque measurement, having excellent workability suitable for mass-production, and capable of avoiding a problem of damage in heat treatment. The torque-detecting device constituted of a portion (3) subjected to torque detection provided on a surface layer portion of a steel torque-transmitting shaft (2), a detecting coil (4) provided opposite the outer periphery of the portion (3) without contact, and detected signal-processing means (5). The portion (3) subjected to torque detection is a magnetostriction material layer constructed from an Al diffusion layer. In the diffusion layer, Al is diffused in the steel material such that its concentration gradually diminishes from the surface toward the center of the shaft.

摘要： A bearing device for a wheel, where preload control is easy and a uniform amount of preload can be applied even if a bearing seal is installed in the bearing device. The bearing device rotatably supports a wheel relative to a vehicle body and has an outer member (1), an inner member (2), and rolling bodies (3) interposed between both members. The outer member (1) has on its outer periphery a vehicle body installation flange (1a), and double-row rolling surfaces (6, 7) are formed on the inner peripheral surfaces of the outer member. Rolling surfaces (8, 9) facing the rolling surfaces (6, 7) of the outer member (1) are formed on the inner member (2). Between the rolling surfaces of both members (1, 2) are interposed the rolling bodies (3) in double rows. A sensor (4) for detecting the amount of preload of the bearing is provided on either the outer member (1) or the inner member (2).

摘要： [PROBLEMS] A bearing device where preload can be variably set to an amount adequate for a traveling condition of a motor vehicle. [MEANS FOR SOLVING PROBLEMS] In a bearing device for a wheel, where a predetermined preload has been applied to a double-row roller bearing, an outer member (7) is constituted of an outer ring member (9) and an outer ring (10) as a separate body. One (9a) of outer rolling raceways is formed on the inner periphery of the outer ring member (9). The outer ring (10) is press-fitted on the outer ring member (9) and the other outer rolling raceway (10a) is formed on the inner periphery of the outer ring (10). An electrostrictive element (15) is installed at a portion where the outer ring (10) and the outer ring member (9) are butted. The electrostrictive element (15) is extended when a predetermined voltage is applied to it according to an output signal from a steering angle sensor, vehicle speed sensor, etc.
