- the restricting portion 41B guides the movement of the flange 31 in the axial direction.
- a plurality of locations in the circumferential direction of the outer peripheral surface of the flange 31 abut against the restricting surface 41C in the radial direction of the flange 31 respectively. That is, the flange 31 and the worm wheel housing member 41 have engagement portions that engage with each other in the radial direction of the flange 31 at locations different from the locations of the mounting portion 31A and the tightening portion 44 where the bolts 30 are provided.
- Fig. 7 shows the configuration of a comparative example.
- a flat surface 31D perpendicular to the radial direction of the flange 31 is provided at the tip of the mounting portion 31A of the flange 31.
- the restricting portion 41B is provided on the tightening portion 44 .
- Each restricting portion 41B is positioned radially outward of the flange 31 with respect to the corresponding mounting portion 31A of the flange 31 .
- Each regulation surface 41C is a plane parallel to the plane 31D of the corresponding mounting portion 31A.
- each flat surface 31D of the flange 31 is guided by the corresponding flat regulating surface 41C, thereby regulating the rotation of the flange 31 about its axis. Therefore, the mounting attitude of the flange 31 in the rotational direction is determined. Further, each flat surface 31D abuts on the corresponding restricting surface 41C in the radial direction of the flange 31, thereby restricting the radial movement of the flange 31. As shown in FIG. Therefore, the lower tube 17 and the housing 18 are maintained coaxially.

As shown in FIG.
- the worm wheel housing member 41 has a restriction portion 41B at a location different from the fastening portion 44 through which the bolt 30 is passed. Therefore, each restricting portion 41B can be provided so as to be positioned inside the virtual circle CB that circumscribes the head portions 30A of the two bolts 30 when viewed from the axial direction of the steering column 15 . Therefore, compared to the case where each restricting portion 41B protrudes outside the imaginary circle CB as in the comparative example of FIG. In addition, it becomes easier to secure an installation space for the steering device 1 in the vehicle.

- the three restricting portions 41B are spaced apart from each other in the circumferential direction of the worm wheel housing member 41 . That is, the flange 31 is supported from three different radial directions. Therefore, when the lower tube 17 and the housing 18 are assembled, the radial movement of the flange 31 can be appropriately restricted.
- the three restricting portions 41B are provided dispersedly in two regions A1 and A2 of the worm wheel housing member 41 bounded by the straight line L1 when viewed from the axial direction of the worm wheel housing member 41. Therefore, the direction in which the flange 31 is supported can be made significantly different. Therefore, the radial movement of the flange 31 can be restricted more appropriately.
- the worm wheel housing member 41 may have two restricting portions 41B.
- the two restricting portions 41B are preferably located on opposite sides of the worm wheel housing member 41 in the radial direction.
- the regulating portion 41B in the area A1 is in the direction of approximately 10:30, and the regulating portion 41B in the area A2 is at about 10:30.
- 41B is provided in the direction of approximately 4:30. Also in this way, when the lower tube 17 and the housing 18 are assembled, the radial movement of the flange 31 can be restricted.
- the worm wheel housing member 41 may have four or more restricting portions 41B.
- the restricting portion 41B in the area A2 may be provided so as not to protrude outward from the outer peripheral surface of the worm wheel housing member 41 when viewed from the axial direction of the worm wheel housing member 41.
- the restricting portion 41B in the area A2 is provided on the end surface of the worm wheel housing member 41 where the opening 41A opens.
- the outer surface of the restricting portion 41B within the region A2 is flush with the outer peripheral surface of the worm wheel housing member 41, or is positioned radially inward of the outer peripheral surface of the worm wheel housing member 41.
- a peripheral portion of the flange 31 is provided with a notch 31C corresponding to the restricting portion 41B in the area A2.
- the restricting portion 41B in the area A2 fits inside the notch 31C of the flange 31. As shown in FIG. By doing so, it is possible to reduce the portion that protrudes outward from the outer peripheral surface of the worm wheel housing member 41 . Further, by providing the restricting portion 41B, even if the flange 31 is assembled to the housing 18 by 180 degrees, the flange 31 cannot be assembled to the housing 18 because there is no notch 31C. Therefore, incorrect assembly can be suppressed.
- each restriction portion 41B may be provided on the flange 31.
- each restricting portion 41B is omitted from the worm wheel housing member 41 and instead connected to the outer peripheral surface of the flange 31 .
- Each restricting portion 41B may be provided integrally with the flange 31 by plastically deforming a metal plate punched into a predetermined shape. The size of each restriction portion 41B can be changed as appropriate.
- Each restricting portion 41 ⁇ /b>B protrudes in the mounting direction DW of the flange 31 from the back surface of the flange 31 facing the worm wheel housing member 41 .
- the flange 31 and the worm wheel housing member 41 have engaging portions that engage with each other in the radial direction of the flange 31 at locations different from the locations of the mounting portion 31A and the tightening portion 44 where the bolts 30 are provided.
- the restricting portion 41B of the flange 31 abuts on the outer peripheral surface of the worm wheel housing member 41 at a plurality of points in the circumferential direction of the flange 31 in the radial direction. Therefore, when the lower tube 17 and the housing 18 are assembled, the radial movement of the flange 31 is restricted.
- Both the worm wheel housing member 41 and the flange 31 may be provided with the restricting portion 41B.
- the steering device 1 may not be provided with a configuration for adjusting the vertical position of the steering wheel 6 and a configuration for adjusting the axial position of the steering wheel 6 .
- a single non-stretchable support cylinder is provided instead of the upper tube 16 and the lower tube 17.
- the single support cylinder rotatably supports the steering shaft 2 .
- the housing 18 is fixed to the frame 14 of the vehicle body. A configuration in which the support portion 18A and the support shaft 18B are omitted as the housing 18 can be adopted.
