The base member 21 is formed so that its outer shape is slightly larger than the opening 14, and a through hole 31 that can penetrate the steering shaft 17 is formed in the approximate center.
By forming the outer shape of the base member 21 substantially larger than the opening 14, the opening 14 can be covered with the base member 21 by covering the base member 21 from above the opening 14.
Further, in a state where the opening 14 is covered with the base member 21, the steering shaft 17 is passed through the through hole 31.

In addition, a pair of clips 22 are integrally formed on the back surface 21 c of the upper half 21 a facing the dashboard 13 in the base member 21.
The pair of clips 22 protrudes toward the dashboard 13 from a portion of the back surface 21c of the upper half 21a that is spaced a predetermined distance in the vehicle width direction.
The upper half 21 a of the base member 21 is attached to the dashboard 13 by passing the pair of clips 22 through the attachment holes 33 of the dashboard 13 and engaging them.

  The hook device 24 is provided so as to protrude from the back surface 21 c of the lower half 21 b facing the floor panel 12 in the base member 21.

  As shown in FIGS. 3 and 4, the hook device 24 includes a hook 25 integrally formed on the back surface 21 c of the base member 21, and a weakened portion provided in the vicinity of the root 25 (hereinafter referred to as the hook root) 25 a of the hook 25. 26.

The hook 25 is provided so as to protrude from the back surface 21 c of the lower half portion 21 b of the base member 21 that faces the floor panel 12.
The hook 25 has a protrusion 35 protruding from the back surface 21c of the lower half 21b and a protrusion 36 protruding from the tip 35a of the protrusion 35.
The hook 25 is formed in a substantially L shape by the protruding portion 35 and the protruding portion 36.

The protruding portion 35 protrudes from the back surface 21c of the lower half portion 21b toward the opening 14 so as to be substantially orthogonal to the back surface 21c of the lower half portion 21b.
Here, the protrusion part 35 is restrained in the protrusion dimension L1 small.
For this reason, the hook 25 is formed so as not to be elastically deformed with the hook base 25a (that is, the base of the protruding portion 35) as a fulcrum.

The protrusion 36 protrudes from the tip 35 a of the protrusion 35 in a first direction 42 that is different from the protrusion direction 41 of the protrusion 35.
Here, the first direction 42 different from the protruding direction 41 of the protruding portion 35 is a direction substantially orthogonal to the protruding direction 41 in the embodiment.
Therefore, the engaging surface 36a of the protrusion 36 is formed substantially parallel to the back surface 21c of the lower half 21b.

Thereby, the engaging surface 36a of the projection part 36 can be engaged with the peripheral edge (counter member) 14a of the opening 14 formed in the floor panel 12.

Further, the hook 25 is formed in a substantially L shape by the protruding portion 35 and the protruding portion 36.
Therefore, the protrusion 36 (engagement surface 36 a) can protrude substantially parallel to the base member 21.
Accordingly, the floor panel 12 can be suitably sandwiched between the protrusion 36 (engagement surface 36a) and the base member 21, and the base member 21 can be reliably fixed to the floor panel 12.

In addition, since the hook 25 is protruded from the base member 21, the hook 25 can be formed integrally with the base member 21.

It extends so as to be orthogonal (intersect).

One end 51a of the intersecting portion 51 is located at a position offset by a distance L2 from the hook root 25a in the direction orthogonal to the extension line 47.
Further, the other end 51b of the intersecting portion 51 is located at a position offset by a distance L2 from the hook root 25a in the direction orthogonal to the extension line 47.

One extending portion 52 is provided at one end 51 a of the intersecting portion 51.
The one extending portion 52 is formed in a slit shape by extending along the extension line 47 from the one end 51a of the intersecting portion 51 in a direction approaching the hook root 25a.
Furthermore, one extension part 52 is provided at the same axial position 21e as the hook base 25a when the extension line 47 is used as an axis.
