    摘要: A preload inspection method for a bearing device for a vehicle wheel comprises: a first bearing preload value calculation step for calculating a first bearing preload value; a first rotating torque measurement step for measuring a first rotating torque; a caulking step for swaging the small-diameter stepped part to the inner ring; a second bearing preload value calculation step for calculating a second bearing preload value; a second rotational torque measurement step for measuring a second rotational torque; a third bearing preload value calculation step for calculating a third bearing preload value by adding, to the first bearing preload value, a preload change amount based on a differential torque between the first rotating torque and the second rotating torque; and a determination step for determining the suitability of the preload from the second bearing preload value and the third bearing preload value.

    摘要: A cam follower for a rocker arm includes a cylindrical outer ring (11) having an outer circumference surface abutting on a cam, a support shaft (6) to support the outer ring (11), a plurality of rollers (12) arranged in an annular region between the support shaft (6) and the outer ring (11), and a side plate (16) composed of a ring-shaped disk penetrated by the support shaft (6), opposed to an end face (15) of the roller (12), and having an outer diameter Ds smaller than an inner diameter Dr of the outer ring (11). The side plate (16) is arranged at each end of the roller (12), and a relationship Lr
