Then, the anchor base 39 located on the base end side of the anchor pin 31 is fitted and inserted while slidingly contacting the base end side inner surface 35 of each flexible tubular wall piece 34 constituting the tubular portion 25. The anchor portion 42 of the main locking portion 40 is
The distal locking portion 36 is inserted and guided while being in contact with the tapered surface 36a of the distal locking portion 36 while pushing the distal locking portion 36 outward in the radial direction. In addition, since the flange-side opening of the spacer 27 is formed to have a diameter larger than the outer diameter of the anchor base 39 and the taper 35a is formed on the flange side of the base inner surface 35, the anchor base 39 has a cylindrical shape. It can be smoothly inserted into the part 25.

The anchor portion 42 penetrates the distal end gap 37 and has a smaller diameter than the maximum diameter of the conical anchor portion 42 and an outer diameter larger than the distal end gap 37. When the tip locking portion 36 is engaged with the boss portion 41, as shown in FIG. 5, the seat portion 36 b is locked to the jaw portion 42 a of the anchor portion 42.

In addition, the processing cost for the vehicle body panel 23 can be reduced.

In the above-described embodiment, the anchor pins 31 project from the pair of mounting ears 22a projecting from the electric connection box 22, respectively. However, the present invention is not limited to this. The anchor pins 31 are projected from the three mounting ears 22a projecting from the electric connection box 22, and the spacers 27 are temporarily locked in advance, as in the member mounting structure to the panel shown in FIG. 31 are attached to the corresponding mounting holes 24a, 24b, 24 on the vehicle body panel 23.
It can also be inserted and fixed to c.

When the mounting holes 24a, 24b and 24c are located in a place where the worker cannot see or work hard, as shown in FIG. 6, the spacer 27 is temporarily stopped at one place. Insert the anchor pin 31 into the corresponding mounting hole 24
a, and then rotating the electrical junction box 22 with the anchor base 39 of the anchor pin 31 inserted into the mounting hole 24a as a rotation axis, as shown by the arrow (d) in the figure, to obtain another anchor. Pin 31 is attached to corresponding mounting hole 24b,

An anchor pin 31 may be directly provided on the back surface of the main body 2. In this case, the ear portion 22a does not protrude to the side of the electric connection box 22 as indicated by the imaginary line, so that the mounting space can be reduced.

It is needless to say that the number of divisions, the curved shape, and the like of the flexible tubular wall pieces constituting the tubular portion of the spacer according to the present invention can be appropriately changed based on the spirit of the present invention. The member to be fixed to the panel according to the present invention is not limited to the electric connection box in the above-described embodiment. Also in the field, it can be widely used for attaching a member to be attached to a panel.
