  However, the following problems exist in the prior art. That is, when the switch is operated with a finger, it is difficult to operate the switch because the finger only hangs on the lower end of the rear wall portion of the bracket. In addition, if a finger is applied to the lower end of the rear wall, an operation load is generated on the rear wall, so it is necessary to ensure the rigidity of the rear wall. However, since such rigidity is not considered at all, it is the worst. In this case, the rear wall may be damaged.

  An object of the present invention is to provide a vehicle door opening / closing structure capable of ensuring the rigidity of a finger hook while improving the operability of a switch.

  A door opening and closing structure of a vehicle according to the present invention includes a door panel, a switch holder that is attached to the door panel and holds a switch for opening and closing the door panel, a garnish provided to cover the switch holder, and a garnish And a bracket having a finger-hanging portion disposed between the switch holder and the lower end of the garnish, the finger-hanging portion having a finger-holding surface for hooking a finger, on the opposite side of the finger-holding surface in the finger-holding portion The surface is provided with a load-applying rib that protrudes toward the garnish side, and the load-applying rib is configured so that a load is applied to the garnish when a finger is placed on the finger resting surface. To do.

  In such a door opening and closing structure of the present invention, when operating the switch for opening and closing the door panel, the finger is inserted from the lower side of the garnish, and the finger is hooked on the finger-holding surface of the finger-holding portion of the bracket Then, operate the switch with your finger. In this way, the user can easily operate the switch by placing the finger on the finger resting surface. At this time, a load-applying rib protruding to the garnish side is provided on the surface opposite to the finger-mounting surface in the finger-mounting portion, and the load-applying rib is loaded on the garnish when the finger is applied to the finger-mounting surface. Is configured to be added. Therefore, since the operation load generated in the finger hanging portion when the finger is placed on the finger hanging surface is received by the garnish, the rigidity of the finger hanging portion can be ensured.

  Preferably, the back surface of the garnish is provided with a load receiving rib that protrudes toward the finger hanging portion, and the load applying rib is configured to abut against the load receiving rib when the finger is hung on the finger hanging surface. ing. In this case, since it is not necessary to make the protrusion length of the load applying rib longer than necessary, the dent of the finger hooking surface due to resin contraction is less likely to occur during resin molding of the bracket. Thereby, the designability of a finger hook surface can be improved.

  In this case, preferably, the load applying rib has a mountain shape, and reinforcing ribs for the load receiving ribs are provided on both the left and right sides of the load receiving rib on the back surface of the garnish. In this case, since the strength of the load applying rib and the load receiving rib is increased, it is possible to sufficiently ensure the rigidity of the finger hook portion.

  According to the present invention, the operability of the switch can be improved. Moreover, since the rigidity of the finger-hanging portion of the bracket can be ensured, the finger-hanging portion can be prevented from being damaged when the switch is operated with the finger.

  FIG. 1 is a rear view showing a part of a rear end portion of a vehicle provided with an embodiment of a door opening / closing structure according to the present invention, and FIG. 2 is an enlarged sectional view taken along line II-II in FIG. In each figure, the door opening and closing structure 1 of the present embodiment is applied to an openable and closable back door 3 mounted on the rear portion of a vehicle 2.

  A back door panel 4 is disposed at the rear of the vehicle 2. A switch holder 5 is fixed to the back door panel 4. An unlock switch 6 is held on the lower surface of the switch holder 5. The lock release switch 6 is a button switch for releasing the locked state of the back door panel 4 so that the back door panel 4 can be opened and closed in the direction of arrow A in FIG.

  A rear window 7 is disposed on the back door panel 4. A rear wiper 8 is attached to the rear window 7. In FIG. 2, the rear wiper 8 is omitted.

  A rear garnish 9, which is a decorative part, is coupled to the back door panel 4 so as to cover the switch holder 5. The rear garnish 9 is attached with a bracket 11 having a finger hook portion 10 disposed between the lock release switch 6 and the lower end portion 9 a of the rear garnish 9. The rear garnish 9 and the bracket 11 are made of resin.

  As shown in FIG. 3, the finger hooking portion 10 is provided with a finger hooking surface 10 a for hooking a finger F when the lock release switch 6 is operated. The finger hooking surface 10a has a planar shape or a curved surface shape. The lock release switch 6 is disposed on the upper front side of the lower end portion 9 a of the rear garnish 9. For this reason, the finger hooking surface 10 a is inclined with respect to the front-rear direction of the vehicle 2.

  As shown in FIG. 4, fixing pins 12 that protrude toward the back door panel 4 are provided on both the left and right sides of the rear garnish 9. Insertion holes 13 through which the fixing pins 12 are inserted are respectively formed on the left and right sides of the bracket 11. The rear garnish 9 and the bracket 11 together with the switch holder 5 are attached to the back door panel 4 by fixing the respective fixing pins 12 to the back door panel 4 in a state where the respective fixing pins 12 are passed through the respective insertion holes 13 of the bracket 11. It is attached.

  As shown in FIGS. 3 and 4, a load application rib 14 that protrudes toward the rear garnish 9 is provided on the surface (back surface) opposite to the finger mounting surface 10 a of the finger mounting unit 10. The load applying rib 14 has a mountain shape extending in the width direction (left-right direction) of the bracket 11. For this reason, the strength of the load applying rib 14 is increased.

  On the rear surface of the rear garnish 9, a load receiving rib 15 is provided so as to protrude toward the finger hooking portion 10 and engage with the load applying rib 14. Reinforcing ribs 16 for the load receiving ribs 15 are provided on the left and right sides of the load receiving ribs 15 on the rear surface of the rear garnish 9, respectively. Accordingly, the strength of the load receiving rib 15 is increased.

  In a normal state, a slight gap (for example, about 0.5 mm) is formed between the tip of the load applying rib 14 and the tip of the load receiving rib 15. When the finger F is hung on the finger hooking surface 10a of the finger hooking portion 10 in order to operate the lock release switch 6 (see FIG. 3), a load is applied to the finger hooking portion 10, and the tip of the load applying rib 14 is the load receiving rib 15.
