A crown type cage for a ball bearing includes an annular main portion, a plurality of pillar portions protruding in an axial direction from the main portion at predetermined intervals in a peripheral direction, and a spherical pocket formed between the adjacent pillar portions and capable of holding balls. The pillar portion has a pair of claw portions of which tip end portions are spaced apart from each other, and a connection portion that connects the pair of claw portions. A bottom surface of the main portion is provided with a part protruding in the axial direction.

To provide a gear housing comprising a front housing having a structure which can make the front housing lightweight and which can increase the strength of a continuous section of a worm wheel housing portion and a support portion where stress tends to be concentrated. A front-side housing is made of synthetic resin, and includes a housing front plate portion which constitutes a worm wheel housing portion and a support portion integrated with the housing front plate portion. A reinforcing member made of a metal plate is provided at a corner portion between a front surface of the housing front plate portion and a lower surface of the support portion.

An encodera characteristic of which is changed alternately at an equal interval in a circumferential direction is supported/fixed onto a hubconcentrically with the hub. A sensing portion of a sensorsupported on the outer ringis positioned in close vicinity to a sensed surface of the encoderto face thereto. Width dimensions of first and second sensed portions provided onto the sensed surface are changed continuously in a direction along which a to-be-sensed load is applied. Since a pattern according to which an output signal of the sensoris changed is changed pursuant to a change of the load, the load is derived by observing this pattern. The output signal is also utilized to sense a rotation speed of the hubin ABS or TCS control.

A hub unit for wheel is described, with an outer ring having two bearing tracks on its inner circumferential surface, and a hub having a wheel mount flange on the outer end side and an end portion on the axially vehicle center side. The hub has a first bearing track corresponding to the axially vehicle outer end side bearing track of the outer ring, and an inner ring element fitted on the end portion side of the hub. The inner ring element has on its outer circumference a second bearing track opposed to the axially vehicle center side bearing track of the outer ring, and is fixed on the end portion by plastically deforming the end portion of the hub radially outwardly. Rolling members are provided between the two bearing tracks of the outer ring and the first and second bearing tracks.
