It is pushed in the circumferential direction. At this time, for example, a part of the block 22 abuts on the support plate 21 and the posture of the block 22 is maintained.
  • the rolling elements 4 rotate and revolve. As described later, when the caulking portion 16 is formed, the formation of an indentation on the outer ring raceway 5 and the inner ring raceway 10 is prevented.
  • the die 20 is displaced downward while swinging movement of the rotation axis ⁇ of the die 20 about the main axis ⁇ as the locus of the central axis by the precession motion.
  • the processed portion 28 of the die 20 is pressed against the cylindrical portion 31 of the hub body 13z.
  • the number of rotations (rotational speed) of the swinging motion of the rotation axis ⁇ of the die 20 about the main axis ⁇ is made different from the number of rotations (rotational speed) of the rotation drive means 19.
  • the swinging movement of the pressing die 20 is stopped, and the pressing die 20 is retracted upward.
  • the rotation driving means 19 is stopped to stop the rotation of the outer ring 2, and thereafter, the adapter 80 of the rotation driving means 19 is retracted upward.
  • the hub unit bearing 1 is obtained by removing the hub main body 13 from the support portion 18.
  • the blocks 22 are arranged at a plurality of circumferentially equally spaced locations. Further, each block 22 is given a downward elastic force by an elastic member 27. Therefore, the block 22 whose tip end face the axially inner side (the inner side of the projection 9 in the axial direction) of the stationary flange 6 is the tip end face of the block 22 as the rotary drive means 19 is displaced downward. And the axially inner surface of the stationary flange 6 abut. Even when the rotational drive means 19 (adapter 80) is displaced further downward, the elastic member 27 is elastically deformed and remains at the vertical position as it is.
  • a guide member 25 which is a rolling bearing or a sliding bearing using a synthetic resin is rotatably supported at the end of the block 22.
  • the outer peripheral surface of the guide member 25 pushes the side surface of the protrusion 9 of the stationary flange 6 in the circumferential direction. This prevents damage such as scratches from being generated on the side surface in the circumferential direction of the protrusion 9 and prevents the outer peripheral surface of the guide member 25 from being worn.
  • the elastic member 27 disposed between the support plate 21 and the block 22 can be omitted.
  • the number of blocks of the rotary drive means and the arrangement in the circumferential direction when the rotary drive means is displaced in the direction approaching the support portion, the circumference of the rotary drive means and the stationary flange. Regardless of the phase with respect to the direction, at least one of the blocks constituting the rotary drive means and the stationary flange can be engaged so as to be able to transmit power in the rotational direction. It is preferable to set appropriately according to the shape. That is, as long as at least one block and the stationary flange can be engaged so as to transmit power in the rotational direction, the plurality of blocks can be arranged at uneven intervals in the circumferential direction.
  • the number of blocks can be set according to the shape of the stationary flange, and can be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or 11 or more. For example, the number of blocks is preferably 6 to 8.
  • the number of blocks may be six or less or one.
  • FIG. 8 shows another example of the block 22.
  • the entire guide member 25 of the block 22 is disposed inside the housing member 26 of the support plate (adapter main body) 21.
  • FIG. 8B in the protruding state, a part of the guide member 25 of the block 22 protrudes with respect to the support plate 21 and the remaining part of the guide member 25 is a storage member 26 in the support plate 21. Placed inside the
  • the present invention is not only a hub unit bearing for a driven wheel in which the hub body is solid, but also a drive wheel provided with a spline hole for engaging the drive shaft in a torque transmittable manner at the central portion of the hub body. It can also be applied to hub unit bearings. Also, the case has been described above in which the present invention is applied to a so-called 2.5th generation hub unit bearing provided with a hub in which a pair of inner rings are externally fitted to a hub body.
  • the present invention is a so-called third generation, having a hub in which the axially outer inner ring raceway is directly formed on the axially outer peripheral surface of the hub body and the inner ring is externally fitted on the axially inner side of the hub body.
  • the present invention can also be applied to hub unit bearings that are loose.
