You may comprise so that it may insert in part 5S). In a state where the panel member 6 is fixed to the base member 1 via the plurality of mounting clips 8 and the plurality of openings 4, the guide pin 9 inserted into the guide hole 5 is the inner peripheral portion of the guide hole 5. It is arrange | positioned in the position which does not contact 5S, and a clearance gap is provided between the guide pin 9 and the inner peripheral part 5S. Here, for convenience of explanation, the gap located below the guide pin 9 is referred to as a gap S1, and the gap located above the guide pin 9 is referred to as a gap S3.

  Specifically, the direction in which the guide pin 9 is inserted into the guide hole 5 is defined as the axial direction AR, and the direction intersecting the axial direction AR (the direction orthogonal to the present embodiment) is the specific direction DR. If so, a recessed portion 9G having a shape recessed in the specific direction DR is provided at the position of the root 9K (the hanging portion 6F side) of the guide pin 9 of the present embodiment. The surface of the recess 9 </ b> G is located closer to the inner diameter side of the guide pin 9 than the surface 9 </ b> S of the portion 9 </ b> T on the distal end side of the guide pin 9.

(Panel member fixing method)
2 and 5, as described above, panel member 6 and in-vehicle device 7 are assembled to receiving portion 1S of base member 1 in a state of being integrated with each other. Concerning the panel member 6 arranged in the front part of the passenger compartment, the design is improved by configuring the panel member 6 so as not to enter a parting line (part line) and making the panel member 6 as large as possible. Is possible. However, when the panel member 6 and the in-vehicle device 7 which are enlarged are integrated with the vehicle main body (base member 1) in an integrated state, the assembly work is difficult unless any measures are taken. It is possible to become.

  In the present embodiment, for example, the operator lifts the integrated panel member 6 and the in-vehicle device 7 so as to face the in-vehicle device 7 from the front (facing the in-vehicle device 7 from the front). The operator inserts the guide pin 9 into the guide hole 5 before inserting the mounting clip 8 into the opening 4, and performs an approximate positioning of the panel member 6 (see FIG. 5). Therefore, the guide pin 9 has a longer length than the mounting clip 8.

  In general, an operator can pay sufficient attention to the vicinity of the in-vehicle device 7, but it is often difficult to pay sufficient attention to a portion far from the in-vehicle device 7. In the present embodiment, the guide pin 9 provided on the panel member 6 is outside in the vehicle width direction (the side farther from the in-vehicle device 7) than the central portion 6Q in the vehicle width direction of the extending portion 6R (FIG. 3). Is located. By configuring so that the positioning is performed at the location where the guide pin 9 is provided, the operator can pay attention to the end of the panel member 6. Compared with the case where the guide pin 9 is provided in the vicinity of the vehicle-mounted device 7, according to this configuration, the panel member 6 is brought into contact with the base member 1 (instrument panel 2) or the instrument panel is brought into contact with the panel member 6. It can suppress that the surface of 2 is damaged.

  In the present embodiment, the surface 9S of the tip portion 9T of the guide pin 9 is set as a reference in the height direction at the time of insertion. When the guide pin 9 is inserted into the guide hole 5, the guide pin 9 is inserted into the guide hole 5 while the surface 9 S of the portion 9 T on the tip side of the guide pin 9 is brought into sliding contact with the inner peripheral portion 5 S of the guide hole 5. Insert into the. A margin (space corresponding to the gap S1) is provided below the guide pins 9 in the direction of gravity. In this state, a gap S2 having a certain size is formed between the panel end 6U and the instrument panel 2.

  The guide pin 9 enters the guide hole 5 along the axial direction AR. When the surface 9S of the tip portion 9T of the guide pin 9 is brought into sliding contact with the inner peripheral portion 5S, the inner peripheral portion 5S of the guide hole 5 is disposed at the position of the recess 9G (in other words, The front end of the mounting clip 8 (FIG. 2) is inserted into the opening 4 (FIG. 2) before the surface 9S of the guide pin 9 is separated from the inner peripheral portion 5S of the guide hole 5. In the specific direction DR, the recess 9G of the present embodiment has a shape that is recessed in a direction opposite to the direction in which the panel end 6U faces the protruding surface 2T (the direction facing the panel). The member 6 can be stably assembled to the base member 1.

  Even if the operator tries to move the entire panel member 6 in the direction in which the panel end 6U approaches the instrument panel 2, the surface 9S of the guide pin 9 is the inner peripheral portion of the guide hole 5. The movement of the base member 1 in the same direction is restricted by being in contact with 5S, and the panel end 6U of the panel member 6 is brought into contact with the base member 1 (instrument panel 2). It is possible to prevent the surface of the ment panel 2 from being damaged.

  Contrary to the above, even if the guide pin 9 moves so as to shift downward when the guide pin 9 is inserted into the guide hole 5, this is the direction in which the panel end 6U moves away from the instrument panel 2. . Therefore, the panel end 6U of the panel member 6 does not contact the base member 1 (instrument panel 2).

  In the present embodiment, the side in the direction in which the panel end 6U approaches the protruding surface 2T is set as a reference in the height direction when the guide pin 9 is inserted. The guide pin 9 is inserted into the guide hole 5 while the guide pin 9 and the guide hole 5 are in sliding contact with each other, and the attachment clip 8 enters the opening 4 when the guide pin 9 is inserted as it is. Therefore, the concave portion 9G is formed on the side that contacts the inner peripheral portion 5S of the guide hole 5.

  Referring again to FIG. 4, in a state where the panel member 6 is fixed to the base member 1 through the plurality of mounting clips 8 and the plurality of openings 4, the guide pin 9 inserted into the guide hole 5 is The guide hole 5 is disposed at a position not in contact with the inner peripheral portion 5S, and a gap (FIG. 4) is provided between the guide pin 9 and the inner peripheral portion 5S. In FIG. 4, a gap S3 between the upper surface of the guide pin 9 and the inner peripheral portion 5S of the guide hole 5 is a gap generated by providing the guide pin 9 with a recess 9G. 9U) and the inner peripheral portion 5S of the guide hole 5 are gaps (there is a margin below) due to the enlarged guide hole 5. This relative positional relationship between the guide pin 9 and the inner peripheral portion 5 </ b> S of the guide hole 5 is maintained by the plurality of attachment clips 8 being engaged with the plurality of openings 4.

  As described at the beginning, the panel member 6 and the base member 1 fixed to each other may vibrate. For example, when the panel member 6 and the base member 1 are used as an interior member of a vehicle, the panel member 6 and the base are affected by an influence caused by traveling or an influence caused by a vibration source such as an engine. The member 1 often vibrates. In the present embodiment, when the panel member 6 is fixed to the base member 1, the guide pin 9 is disposed at a position that does not contact the inner peripheral portion 5 </ b> S of the guide hole 5. A gap S1 (FIG. 4) is provided between the inner peripheral portion 5S. Therefore, the guide pin 9 hardly contacts the inner peripheral portion 5S. Even if the panel member 6 and the base member 1 vibrate, the generation of noise due to the guide pin 9 coming into contact with the inner peripheral portion 5S of the guide hole 5 is effectively suppressed. .

(Comparative example)
With reference to FIG. 6, the fixing structure 10A of the panel member in a comparative example is demonstrated. In the fixed structure 10A, a cushioning material 9F such as felt is provided around the guide pin 9A. According to the said structure, the effect similar to the above-mentioned embodiment can be acquired in the point that generation | occurrence | production of unusual noise can be suppressed. However, in the case of this comparative example, a cushioning material 9F such as felt is required. Therefore, it can be said that the above-described embodiment is superior to this comparative example in terms of manufacturing cost and manufacturing efficiency because it does not require a felt or the like.

(Modification)

It has a concave shape.

  On the other hand, in the present modification, the recess 9G has a shape that is recessed in the same direction as the direction in which the panel end 6U faces the projecting surface 2T (the facing direction) in the specific direction DR. . The surface 9S of the portion 9T on the distal end side of the guide pin 9 (in this embodiment, the surface 9S corresponds to the lower surface) is set as a reference in the height direction at the time of insertion. When the guide pin 9 is inserted into the guide hole 5, the guide pin 9 is guided while the surface 9 S (lower surface) of the portion 9 T on the tip end side of the guide pin 9 is in sliding contact with the inner peripheral portion 5 S of the guide hole 5. Insert into the hole 5.

  The guide pin 9 enters the guide hole 5 along the axial direction AR. When the surface 9S of the tip portion 9T of the guide pin 9 is brought into sliding contact with the inner peripheral portion 5S, the inner peripheral portion 5S of the guide hole 5 is disposed at the position of the recess 9G (in other words, The front end of the mounting clip 8 (FIG. 2) is inserted into the opening 4 (FIG. 2) before the surface 9S of the guide pin 9 is separated from the inner peripheral portion 5S of the guide hole 5. The recess 9G of the present modification has a shape that is recessed in the same direction as the direction in which the panel end 6U faces the projecting surface 2T (the facing direction) in the specific direction DR. Can be stably assembled to the base member 1.

  In the above-described embodiment, when the guide pin 9 is inserted into the guide hole 5, a margin is provided on the lower surface side of the guide pin 9. In the above-described modified example, the guide pin 9 has the guide hole 5. It is designed to provide an allowance on the upper surface side of the guide pin 9 when inserting.
