A wire 24 is wound around these pulleys 20 and 22, and the wire 24 is wound around a drive pulley 28 connected to an output shaft of a motor 26 disposed in front of the guide rail 18. The pulley 20 and the pulley 2
The carrier plate 16 is fixed to the wire 24A between the two.

Accordingly, the rotation of the motor 26 causes the wire 24A between the pulley 20 and the pulley 22 to move in the vertical direction, and the movement causes the door glass 14 to move up and down.

As shown in FIG. 2, the front side door 12 includes a side door outer panel 30 (hereinafter, referred to as a door outer panel 30) that forms the outside of the front side door 12, and a side that forms the vehicle side of the front side door 12. Door inner panel 32 (hereinafter door inner panel 3)
2). On the door inner panel 32 side of the door outer panel 30, an outer reinforcement 34 is disposed along the belt line 12 </ b> A, and the outer reinforcement 34 forms a closed cross section 36 extending in the front-rear direction with the door outer panel 30. I have. On the door outer panel 30 side of the door inner panel 32, an inner reinforce 38 is disposed at a portion facing the outer reinforce 34, and the inner reinforce 38 is a closed cross section extending in the front-rear direction with the door inner panel 32. 40.

The upper end of the guide rail 18 is in contact with the general surface 38A of the inner reinforcement 38.

As shown in FIG. 1, the outer reinforcement 34 extends from the vicinity of the front end of the front side door 12 to the vicinity of the rear end thereof, and the inner reinforcement 38 is slightly shorter in the front and rear than the outer reinforcement 34.

As shown in FIG. 3, the outer reinforce 34 has a portion on both sides in the front-rear direction avoiding the pulley 20.
Outer side protrusions 42 bulging toward the inner reinforcement 38 are formed.

As shown in FIG. 1, these outer-side projections 42 are provided at the same height as the pulley 20 and at a position that does not overlap with the occupant 44 in a side view.

As shown in FIG. 3, an inner side protrusion 46 swelling toward the outer reinforcement 34 is formed at a portion of the inner reinforcement 38 facing the outer side protrusion 42. The pulley 20 contacts the general surface 34A of the outer reinforcement 34, and the pulley 20
However, before being sandwiched between the general surface 34A of the outer reinforcement 34 and the general surface 38A of the inner reinforcement 38, the inner projection 46 and the outer projection 42 come into contact with each other.

As shown in FIG. 3, a gap 47 is formed between the outer projection 42 and the inner projection 46 so that the door glass 14 can move up and down. Also, the protrusion amount N1 of the outer protrusion 42 and the protrusion amount N2 of the inner protrusion 46.
Is larger than the protrusion amount M of the pulley 20 from the general surface 38A of the inner reinforcement 38, and the length L1 of the outer protrusion 42 is greater than the length L2 of the inner protrusion 46. It is longer on both sides.

Next, the operation of this embodiment will be described. In the vehicle door structure of this embodiment, when a load acts on the front side door 12 from the outside in the vehicle width direction at the time of a side collision, the outer reinforce 34 is integrally formed with the door outer panel 30 by the load, so that the door inner panel 32 is closed. Move in the direction (the direction of arrow A in FIG. 2). At this time, in this embodiment,
The outer side protrusions 42 of the outer reinforcement 34 and the inner side protrusions of the inner reinforcement 38 are provided at the same height as the pulleys 20 on both sides in the front-rear direction avoiding the pulleys 20 and provided at positions not overlapping the occupant 44 in side view. 46 come into contact with each other before the pulley 20 comes into contact with the general surface 34A of the outer reinforcement 34.

Therefore, unlike the conventional structure, the occupant does not come into contact with the inside of the vehicle interior of the front side door which has been pushed to the bottom by the pulley. That is, the occupant 44 is able to deform the door inner panel 32 between the general surface 34A of the outer reinforcement 34 and the pulley 20 (N1 + N).
2-M) will come into contact with the remaining part,
Due to the deformation of the door inner panel 32, the load characteristics applied to the occupant 44 can be improved.

In this embodiment, the length L1 of the outer projection 42 is longer on both the front and rear sides than the length L2 of the inner projection 46.
As a result, even when the outer projection 42 moves in the front-rear direction with respect to the inner projection 46, the outer projection 42 and the inner projection 46 come into contact with each other without fail. I have.

As shown by imaginary lines in FIG. 3, a reinforce 43 having a hat-shaped cross section may be fixed in the outer projection 42. In this case, Reinforce 43
A gap is formed between the top portion 43A of the door and the door outer panel 30, or they are bonded with a mastic sealer. Similarly, a reinforce 49 having a hat-shaped cross section may be fixed in the inner projection 46. In this case, a gap is formed between the top 49A of the reinforce 49 and the door inner panel 32, or they are bonded with a mastic sealer. By doing so, the door inner panel 3
2. Door outer panel 30 and inner reinforcement 3
8. The reinforce 49 and the reinforce 43 can be deformed before the outer reinforce 34 reaches the bottom of each other, and the load characteristics applied to the occupant 44 can be further improved by this deformation.

Next, a second embodiment of the vehicle door structure of the present invention will be described with reference to FIG. The same members as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIG. 4, in the vehicle door structure of the present embodiment, the outer side projection 4 of the outer reinforcement 34 is taken into consideration in consideration of the deformation state of the door outer panel 30 at the time of a side collision.
2 is longer downward than the inner protrusion 46 of the inner reinforcement 38, and the lower end 42 </ b> A of the contact surface of the outer protrusion 42 of the outer reinforcement 34 is connected to the inner protrusion 46 of the inner reinforcement 38. Is lower than the lower end 46A of the contact surface by a height H. Further, the amount of rearward extension of the outer-side protrusion 42 with respect to the inner-side protrusion 46 is greater than the amount of frontward extension.

Therefore, in the vehicle door structure of the present embodiment,
At the time of a side collision, the outer projection 42 of the outer reinforcement 34 is raised above the inner projection 46 of the inner reinforcement 38 due to the deformation of the door outer panel 30 (FIG. 4).
(In the direction of arrow B) or when moving backward.
The outer-side protrusion 42 and the inner-side protrusion 46 can be reliably brought into contact with each other, and the load characteristics applied to the occupant can be reliably improved.

As shown by the imaginary line in FIG. 4, the outer reinforcement 34 facing the carrier plate 16 is provided.
May be moved in a direction away from the carrier plate 16 to increase the deformation allowance of the outer reinforcement 34. Similarly, carrier plate 1
General surface 38A of inner reinforcement 38 facing 6
May be moved in a direction away from the carrier plate 16 to increase the deformation allowance of the inner reinforcement 38. By doing so, when the outer reinforce 34 and the inner reinforce 38 have high strength, even when the carrier plate 16 or the like is sandwiched between the outer reinforce 34 and the inner reinforce 38, further deformation does not progress. The deformation of the outer reinforcement 34 and the deformation of the inner reinforcement 38 can prevent the load characteristics applied to the occupant from being deteriorated.

Next, a third embodiment of the vehicle door structure according to the present invention will be described with reference to FIGS.

The same members as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIG. 5, in this embodiment, a deformation strength reducing portion 60 is formed at a portion of the outer reinforcement 34 facing the pulley 20. In the deformation strength reducing portion 60, a through hole 62 is formed at a bent portion at the lower edge of the general surface 34 </ b> A of the outer reinforcement 34.

As shown in FIG. 6, a plurality of through-holes 62 are formed at predetermined intervals, and when a load acts on the deformation strength reducing portion 60 from the inside of the door (the direction of arrow C in FIG. 6). Are easily recessed.

Therefore, in the vehicle door structure of the present embodiment,
At the time of a side collision, when the outer reinforcement 34 moves integrally with the door outer panel 30 toward the pulley 20 and a load acts on the deformation strength reducing portion 60 from the direction of arrow C by the pulley 20, it is indicated by the imaginary line in FIG. As described above, the deformation strength reducing portion 60 is recessed toward the door outer panel 30. For this reason, the occupant does not come into contact with the inside of the vehicle interior of the front side door, which is in the state of the bottom end protruded by the pulley as in the conventional structure. That is, the occupant 44 comes into contact with the portion where the door inner panel 32 can move toward the door outer panel 30 by the deformation strength reducing portion 60, so that the movement of the door inner panel 32 gives a load characteristic to the occupant. Can be improved.

In this embodiment, the outer reinforcement 34 is provided with the deformation strength reducing portion 60. However, the inner reinforcement 38 may be provided with a deformation strength reducing portion instead. Further, both the outer reinforcement 34 and the inner reinforcement 38 may be provided with a deformation strength reducing portion.
Further, in the present embodiment, the through-hole 62 is formed to form the deformation strength reducing portion 60. However, instead of the through-hole 62, a slit,
A bead or the like may be provided.
