arm portions

114a and 114b. It extends to the vicinity of the lower end of the first panel 104. Further, the rib 120 is formed so that its height is rapidly lowered in the vicinity of the substantially central portion of the

arm portions

114a and 114b.

In other words, the rib 120 is not provided on the lower end side from the center along the length direction of the

arm portions

114a and 114b.

The joining portion 116 is formed substantially parallel to the lower end portion of the first panel 104, and an engagement piece 112 protruding upward (in the direction of arrow Z2) is provided on the inner edge portion on the first panel 104 side. In addition, the lower end of the joint portion 116 has a first tapered surface 122 that gradually decreases in thickness toward the tip. The first tapered surface 122 is formed so as to face the surface 104 a side of the first panel 104.

The engaging piece 112 is formed in, for example, a substantially rectangular shape and plate shape having a predetermined thickness, and its lower end is joined to the joining portion 116 of the base portion 110, and the tip portion that is the upper end is the first end. The panel 104 extends to a position spaced apart from the lower end of the panel 104 by a predetermined distance. That is, the engagement piece 112 is joined to the joining portion 116 in the base portion 110 only at the lower end portion, and has a cantilever structure in which the upper side can be bent by a predetermined angle with the support portion as a fulcrum.

Further, a protrusion 124 that gradually bulges from the lower end portion toward the upper end portion is formed on the surface side of the engagement piece 112. For example, the protrusion 124 is formed in a substantially triangular cross section when viewed from the width direction of the first panel 104, and its upper end portion is formed to be the thickest, and the upper end portion extends in the extending direction of the engagement piece 112. It is formed in a substantially orthogonal plane (see FIGS. 11 and 12).

On the other hand, the second panel 106 is made of, for example, a flat plate body having a predetermined thickness made of a resin material, and the upper end portion of the second panel 106 is substantially the same as the extending direction of the second panel 106. A seat 126 that is orthogonal and extends with a predetermined width toward the back surface 106b is formed, and second engagement means 128 that is connected to the first panel 104 is provided.

The seat 126 extends substantially horizontally along the width direction of the second panel 106 in the vehicle front-rear direction (arrows X1 and X2), and the end on the back 106b side is upward (arrows). A wall portion 130 is formed substantially upright in the direction (Z2). And when the 1st panel 104 is connected to the 2nd panel 106 at the seat part 126, the lower end part contacts and is hold | maintained (refer FIG. 11).

The second engagement means 128 includes an engagement hole 132 formed so as to penetrate a part of the seat 126 at the upper end portion of the second panel 106, and a connection wall formed so as to face the engagement hole 132. 134, the engagement hole 132 is formed in a substantially rectangular shape that is long along the vehicle front-rear direction (arrow X1, X2 direction) of the second panel 106, and the seat 126 is formed in the engagement hole 132. The part provided with is formed wider than other parts. That is, the seat portion 126 is formed wide so that only a portion where the engagement hole 132 is provided protrudes to the back side.

The engagement hole 132 is formed with a width dimension and a thickness dimension into which the base portion 110 of the first engagement means 108 can be inserted, and is gradually lowered downward on the inner wall surface on the second panel 106 side. The second tapered surface 136 is inclined so as to be wider. Further, a claw portion 138 with which the protrusion 124 of the first panel 104 is engaged is formed at a portion on the back surface 106 b side of the second panel 106 with respect to the second tapered surface 136.

The connecting wall 134 is provided above the engagement hole 132 and on the back surface 106b side of the second panel 106, and is formed in a straight line along the front-rear direction (arrow X1, X2 direction) of the vehicle. Then, both end portions of the connecting wall 134 are connected to the end portions of the wall portion 130, respectively. In other words, the connecting wall 134 is formed so as to be offset from the end of the wall 130 divided by the engagement hole 132 by a predetermined distance on the back surface 106b side, and at the same height, the wall It is formed substantially parallel to the portion 130.

The vehicle door lining 100 according to the second embodiment of the present invention is basically configured as described above. Next, the first panel 104 and the first panel 104 constituting the vehicle door lining 100 are the same as those described above. A case where the two panels 106 are connected will be described.

First, as shown in FIG. 10 and FIG. 12, the first panel 104 is upward (in the direction of arrow Z2) with respect to the vehicle interior side of the door panel (not shown), and the second panel 106 is downward (with respect to the first panel 104). For example, with the second panel 106 fixed to the door panel, the lower end of the first panel 104 is brought closer to the upper end of the second panel 106, The first engagement means 108 is inserted into the engagement hole 132 in the second engagement means 128.

When the base portion 110 and the engagement piece 112 of the first engagement means 108 are inserted into the engagement hole 132, the first tapered surface 122 of the base portion 110 is formed on the inner wall surface of the engagement hole 132. Further, it is inserted into the second taper surface 136 while being in contact with the second taper surface 136, and further, the surface of the claw portion 138 is inserted while being guided by the second taper surface 136. At this time, the engaging piece 112 is inserted while being bent by being elastically deformed toward the back side under the contact action with the second tapered surface 136. In addition, since the engagement piece 112 is not provided with the rib 120 to the lower end portion thereof, it can be suitably elastically deformed and bent.

The base portion 110 and the engaging piece 112 are all inserted into the engaging hole 132, so that the pressing force to the engaging piece 112 by the second tapered surface 136 is eliminated, and the engaging piece 112 is elastic. By returning to the second panel 106 side by force, the upper end portion of the protrusion 124 is engaged with the claw portion 138. Thereby, the first engagement means 108 is restricted from moving upward (in the direction of arrow Z2) with respect to the engagement hole 132, and the base portion 110 of the first engagement means 108 is Movement in the front-rear direction (arrow X1, X2 direction) is restricted.

At this time, the first engaging means 108 is inserted into the second engaging means 128 so that the lower end portion of the first panel 104 is on the surface 106a side with respect to the wall portion 130 of the second panel 106, and The engagement hole 132 is covered with the lower end of the first panel 104 and is not visible from the outside (see FIGS. 8 and 11).

As a result, the first and

second panels

104 and 106 are relative to each other in the vehicle front-rear direction (arrow X1, X2 direction) by inserting the base portion 110 and the engagement piece 112 into the engagement hole 132. And the relative displacement of the first panel 104 relative to the second panel 106 in the upward direction (in the direction of the arrow Z2) is restricted.

As described above, in the second embodiment, in the first and

second panels

104 and 106 constituting the vehicle door lining 100, the lower end portion of the first panel 104 is downward (in the direction of arrow Z1). A first engaging means 108 having a base portion 110 projecting toward the base portion and an engaging piece 112 provided inside the base portion 110 is provided, while an upper end portion of the second panel 106 is A second engaging means 128 that is engaged with the first engaging means 108 is provided on the seat 126 that extends substantially horizontally.

Then, when the base portion 110 and the engagement piece 112 of the first engagement means 108 are inserted into the engagement hole 132 of the second engagement means 128, the contact with the second tapered surface 136 of the engagement hole 132. By suitably bending and elastically deforming the engagement piece 112 under the action, the protrusion 124 of the engagement piece 112 is in a state where the engagement piece 112 is completely inserted into the engagement hole 132. The first panel 104 and the second panel 106 can be reliably connected by returning to a predetermined position by the elastic force and engaging with the claw portion 138.

That is, the thickness dimension of the base portion 110 and the engagement piece 112 constituting the first engagement means 108 is reduced at the engagement position between the first panel 104 and the second panel 106, and the base portion 110 is By fixing the length of the provided rib 120 to a substantially central portion along the height direction of the base portion 110, flexibility on the lower end side of the base portion 110 can be enhanced. Therefore, when the first and

second panels

104 and 106 are connected, the claw portion 138 of the second panel 106 can enter between the lower end portion of the first panel 104 and the engagement piece 112. Further, the stepped shape generated at the joint portion between the first panel 104 and the second panel 106 can be suppressed, and the quality of the vehicle door lining 100 can be improved.

In other words, when the first and

second panels

104 and 106 are connected, the claw portion 138 of the second engagement means 128 is disposed inside the first engagement means 108, thereby It is possible to suppress a protrusion margin of the second panel 106 to the outside with respect to the surface 104a.

The first tapered surface 122 is formed at the lower end of the base portion 110 constituting the first engaging means 108, while the second tapered surface is formed on the inner wall surface of the engaging hole 132 constituting the second engaging means 128. By forming 136, it is possible to improve insertability when the base portion 110 is inserted into the engagement hole 132, and to smoothly engage the base portion 110 in contact with the second tapered surface 136. Since it can guide to the inside of the hole 132, the connection work of the 1st panel 104 and the 2nd panel 106 can be performed much more easily.

It should be noted that the mounting structure of the vehicle door lining according to the present invention is not limited to the above-described embodiment, and various configurations can be adopted without departing from the gist of the present invention.
