DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be explained based on the drawings. FIG. 1 is a diagram showing how a dash silencer and an instrument panel are attached to a dash panel. FIG. 2 is a sectional view of a dash panel with a dash silencer and an instrument panel attached. FIG. 3 is an enlarged sectional view of the attachment portion of FIG. 2. FIG. 4 is a two-sided view showing the pin, (a) is a plan view, and (b) is a front view. Figure 5
is a three-sided view showing the stay, (c) is a plan view,
(d) is a front view, and (e) is a side view.

[0007] A dash silencer 2 made of an elastic material is disposed on the interior side surface of a dash panel 1 constituting the body in order to insulate sound from an engine (not shown). The upper end of this dash silencer 2 has holes 3 at three locations at approximately equal intervals in the width direction of the vehicle.
is provided. When the dash silencer 2 is disposed on the dash panel 1, a stud bolt 4 is welded to the dash panel 1 at the upper part of the dash panel 1 where the hole 3 is located in a convex shape toward the inside of the vehicle interior. The stud bolt 4 has a recess 27 provided at the end of the base 6 of the pin 5.
It is said that it can be fitted to Pin 5 is dash panel 1
The instrument panel 8 is connected to the
It includes a base 6 connected to the dash panel 1, and a tip 7 having a smaller diameter than the base and connected to the instrument panel 8. At the end of the base 6, a recess 27 is provided and a pedestal 9 is provided. A plurality of ribs 10 are provided on the outer periphery of the base 6. Furthermore, a claw 11 for locking the stud bolt 4 is provided on the inner periphery of the recess 27 . A claw 12 is provided on the outer side of the pin 5 at approximately the center in the longitudinal direction. Two claws 12 are provided at mutually opposing positions on the cross section of the pin 5. Moreover, this claw 12 is expanded toward the base 6 side. The tip 7 has a conical shape,
A constricted portion 13 is formed on the base 6 side of this conical portion.

The instrument panel 8 consists of three layers: a resin insert 14, a pad 15, and a skin 16. A bifurcated rib 18 is provided at the end 17 of the upper surface of the insert 14 . A locking piece 24 of the stay 19 is held between the ribs 18 . This stay 1
9 is the lower rib 18 between the locking piece 24 and the locking piece 24.
It consists of a pair of support pieces 26 that sandwich the flange portions 26, a pair of flange portions 23 each having a screw hole 22, and a cylindrical body 20 into which the tip portion 7 of the pin 5 is fitted. The opening of the cylindrical body 20 on the side into which the pin 5 is fitted is tapered and widened. The flange portion 23 is provided so as to face the end of the insert 14 of the instrument panel 8, and
A boss (not shown) corresponding to the screw hole 22 is provided at the end of the screw hole 22 . Moreover, convex portions 30 and 31 are provided on the inner periphery of the cylindrical body 20 to lock the constricted portion 13 of the pin 5. A washer 21 is sandwiched between the claw 12 of the pin 5 and the rib 10, and the dash silencer 2 is sandwiched between the base 9 and the washer 21.

Next, a method for attaching the dash silencer 2 and the instrument panel 8 to the dash panel 1 will be explained. First, the pin 5 is passed through the hole 3 of the dash silencer 2, and the dash silencer 2 is locked to the base portion 6. This locking is achieved by preventing the pedestal 9 from coming off and by press-fitting the rib 10 into the hole 3 to elastically deform the hole 3. Note that the diameter of the hole 3 is the same as or slightly larger than the diameter of the base 6. Next, washer 2
1 into the pin 5 from its tip side, and then insert the washer 21
The dash silencer 2 is pressed down and the dash silencer 2 is elastically deformed. Due to the repulsive force caused by this elastic deformation, the dash silencer 2 is firmly locked by the pin 5. Note that in order to increase this repulsive force, the area of the washer 21 is made large.

The dash silencer 2 can be positioned and attached to the dash panel 1 by fitting the recess 27 of the pin 5 into the stud bolt 4 welded to the dash panel 1 in advance. At this time, the pin 5 is fixed to the stud bolt 4 by the screw thread of the stud bolt 4 engaging the claw 11 provided on the inner periphery of the recess 27 . End 1 of insert 14
The locking piece 24 of the stay 19 is inserted between the ribs 18 provided in the
The stay 19 is fixed to the instrument panel 8 by passing a screw (not shown) through the screw hole 22 of the flange portion 23 and screwing it into a boss (not shown) of the insert 14. . By fitting the tip 7 of the pin 5 into the cylindrical body 20 of the stay 19, the instrument panel 8 is attached to the dash panel 1.
can be installed. At this time, the constriction 13 of the tip 7 is locked by the convex parts 30 and 31 on the inner circumference of the cylinder 20, and the cylinder 20 has an oval cross section compared to the circular cross section of the pin 5. , the pin 5 is fitted into the cylindrical body 20 with some play. This play is for absorbing manufacturing errors of each part.

As described above, in this embodiment, the mounting part of the instrument panel 8 to the dash panel 1 is shared with the locking part of the dash silencer 2, thereby eliminating the need to provide an instrument panel mounting surface on the body. , the vehicle structure is simplified and the vehicle weight can be reduced. Furthermore, the number of parts can be reduced and the yield can also be improved. Moreover, by providing the pin 5 on the dash panel 1 side, the positioning of the dash silencer 2 can be facilitated.

Furthermore, by fitting the stay 19 into the pin 5, the instrument panel 8 can be attached to the dash panel 1.
can be attached, so the installation work efficiency can be improved. Furthermore, since the stud bolt 4 is fitted inside the base 6 of the pin 5, which is the attachment base of the instrument panel 8 to the dash panel 1, the rigidity of the attachment portion of the instrument panel 8 can be improved. Although the present invention has been described above with reference to specific embodiments, the present invention is not limited to such embodiments, and various other embodiments are possible within the scope of the present invention.
