[0007]

The cover engages the protrusion and the locking member from the outside of the vehicle with the engaging groove of the guide rail fixed to the vehicle body panel, whereby the locking member is formed in the engaging groove. And is attached by being prevented from coming off. Therefore, the cover can be fixed at the proper position without being affected by the mounting position of the guide rail with respect to the vehicle body panel.

[0008]

1 shows a vehicle to which the present invention is applied.
Is a sliding door (hereinafter simply referred to as a door) attached to the vehicle body panel (2) so as to be openable and closable, and an upper rail (3) provided along an upper edge of a door opening of the vehicle body panel (2).
And a lower rail (4) provided along the lower edge, and a recess (2) recessed in the front-rear direction of the waist portion of the vehicle body panel (2).
As shown in FIG. 1, a door lock (1) provided behind the door (1) is secured by a guide rail (5) fixed in a).
a) is a fully closed position in which a striker (not shown) fixed to the vehicle body panel (2) is engaged, and a side surface of the vehicle body panel (2) is moved slightly outward from an outer surface of the vehicle body panel (2). It is supported so that it can be opened and closed between a fully open position that has moved rearward in parallel.

The guide rail (5) fixed in the recess (2a) of the vehicle body panel (2) is concealed by a cover (10) fixed to the guide rail (5) so as not to be exposed to the outside.

[0010] The guide rail (5) is integrally formed of a drawn material of aluminum light alloy, and has a U-shaped cross section with a door open side as shown in FIGS.
(1) facing the front-back direction which is the opening / closing direction, and a bottom surface (5a);
A side wall (5b) rising from the inside of the vehicle at the bottom surface (5a);
an upper wall (5f) extending outward from the upper end of b) and an upper wall (5f)
L-shaped top wall (5g) further connected to the top
And an engagement groove formed between the upper wall (5f) and the uppermost wall (5g) and having an open outer side to which the cover (10) is attached.
(5h) and a standing piece standing up a predetermined amount from the outside of the vehicle on the bottom surface (5a)
(5d), and a protruding piece (5e) protruding from the side wall (5b) so as to face the upstanding piece (5d). On the opposing surfaces of the upper wall (5f) and the uppermost wall (5g), there is formed a longitudinally extending ridge portion (12) projecting so as to narrow the opening width of the engaging groove (5h).

The bottom surface (5a) and the upper wall (5f) of the guide rail (5 )
And between, it is connected to the waist part of the door (1), roller unit for guiding the door (1) back and forth along the guide rail (5) (6) is fitted movably. As shown in FIGS. 2 and 3, the roller unit (6) is connected to the door (1) side, and has a substantially U-shaped base plate (7) bent so as to avoid the lower edge of the cover (10). And the base plate
A first roller (8), which is pivotally mounted on (7) with a horizontal axis and rolls on the bottom surface (5a) of the guide rail (5) to support the vertical door weight, and a base plate (7). A second roller (5) which is pivotally mounted with a vertical axis and rolls between the upright piece (5d) and the protruding piece (5e) of the guide rail (5) to suppress the lateral deflection of the door (1). 9).

The cover (10) is formed of a synthetic resin material, and has a concave portion (2a) of the vehicle body panel (2) and a guide rail (5).
The cover (10a) concealed from the outside of the vehicle so as not to be exposed to the outside, and protrudes from the back surface of the cover (10a) toward the opening of the engagement groove (5h) of the guide rail (5). As shown in FIG. 3, a projection (10b) that engages with the engagement groove (5h) is provided.

At several positions in the longitudinal direction of the protruding portion (10b), the engaging portion (5h) is fitted into the engaging groove (5h) and engaged with the ridge portion (12) to prevent the protruding portion (10b) from coming off from the engaging portion (5h). Is fixed. The locking body (11) is formed by an elastically deformable leaf spring, and has a locking piece (11a) at its tip that can engage with the ridge (12) in the engagement groove (5h). .

As shown in FIGS. 2 and 3, the cover (10
a) a roller unit (6) between the lower edge and the recess (2a);
A gap (13) is formed to the extent that the base plate (7) of the roller unit (6) can be inserted. The base plate (7) of the roller unit (6) moves inside the gap (13) by opening and closing movement of the door (1). It moves along the longitudinal direction without interfering with the lower edge of the cover (10a).

As shown in FIGS. 2 and 3, the cover (10)
Is a method for directly engaging a projection (10a) and a locking body (11) provided along a longitudinal direction with an engagement groove (5h) of a guide rail (5) fixed to a recess (2a) from the outside of the vehicle. As a result, the locking piece (11a) of the locking body (11) is elastically deformed and the protrusion (1) is formed.
Engage with 2) to prevent it from falling off, and cover (10a)
The upper back (10c) of the car comes in contact with the body panel (2) from the outside of the car
You.

Therefore, the cover is not affected by the mounting position of the guide rail (5) with respect to the vehicle body panel (2).
The base plate (7) of the roller unit (6) can be fixed at a regular position, and the vertical positional relationship between the cover (10) and the guide rail (5) is kept constant.
However, it does not interfere with the lower edge of the cover (10a) of the cover (10).

[0017]

The present invention has the following effects. (a) The cover can be mounted simply by engaging the protrusions and the locking members of the cover with the engagement grooves of the guide rail, so that the mounting work can be improved. (b) Since the engagement groove is formed integrally with the guide rail,
Accuracy of the positional relationship between the cover and the guide rail can be easily secured.
