The amount of daylight through 3 is increased.

To explain the sunshade main body 22 in more detail, a front flange 31 is formed at the front of the sunshade main body 22. As shown in FIG. The front flange 31 is removably fitted between the weather strip 16 and the opening trim 17, and the sunshade main body 22 is vertically movable around the fitted position of the front flange 31. On the other hand, the rear end of the sun shade body 22 is detachably attached to a bracket 18c attached to the rear edge 18b of the window glass 18 by means of a clip 18d.

Next, the guide means 28 will be explained.
This guide means 28 is formed by slidably fitting both ends of the sliding rod 27 in the vehicle width direction into the curtain 24.
It has an elongated guide hole 34 for guiding the moving end.

That is, ribs 36 are provided on each side opening edge 23c of the light-transmitting opening 23 along the moving direction of the moving end of the curtain 24.
are integrally protruded. Further, a rail 37 is provided along each rib 36 and above the rib 36.

The ribs 36 are cylindrical support portions 38, 38 that are integrally provided on the front and rear sides of the side opening edge 23c.
and a protrusion 39 that is integrally formed between both the support parts 38.

The rail 37 is made of sheet metal and has a U-shaped cross section, and the bottom plates at the front and rear ends are screwed into screws 40 and 4.
0 to the supporting parts 38, 38 by screws.

The guide hole 34 is formed by the gap between the rib 36 and the rail 37. Each end of the sliding rod 27 in the vehicle width direction is fitted into the guide hole 34 . Also, each end of the sliding rod 27 is bent downward, thereby making the curtain 2
4. Movement of the front end in the width direction with respect to the guide means 28 is restricted.

In the sunshade 21 having the above configuration, a stopper surface 42 is formed on the protrusion portion 39 to prevent the sliding rod 27 from further advancing when the curtain 24 advances to fully close the light-transmitting opening 23. Ru.
Moreover, the same curtain 2
The protrusion 39 is the lower surface side of the guide hole 34 so as to be continuous with the stopper surface 42 on the retreating side of the guide hole 34.
A U-shaped locking groove 43 is formed in the side view. This locking groove 43 allows the sliding rod 27 to be removably inserted therein.

Further, the sliding rod 27 slides into contact with the sliding rod 27 that advances so as to fully close the transparent opening 23, and this sliding rod 27
A spring member 44 is provided that elastically urges the locking member to fit into the locking groove 43.

That is, the spring member 44 is a wire rod having a circular cross section and is formed to extend along the rail 37, and the rear end side 44a is formed to meander in an S-shape when viewed from above. On the other hand, front and rear support holes 46 and 47 are formed by cutting and raising the bottom plate of the rail 37 with a predetermined gap in the front and back direction of the bottom plate of the rail 37. The front end side 44b of the spring member 44 is passed through the front support hole 46 from above toward the front and lower side, and the end of the rear end side 44a is adapted to expand and contract the S-shaped portion of the rear end side 44a. Therefore, it is removably fitted into the rear support hole 47.

The front end side 44b of the spring member 44 extends forward and downward so as to pass through the side of the locking groove 43, and the front end side 44b is elastically deformed to be vertically movable.

Further, the front end 44b end of the spring member 44 is configured as follows so that it does not move in the width direction of the protrusion 39.

That is, a guide groove 48 is formed in the protruding portion 39 in front of the stopper surface 42 . On the other hand, the front end side 44b of the spring member 44 extends forward and downward along one side of the protrusion 39, and then its end is once bent in the width direction of the protrusion 39 to form the guide groove 44.
, and is further bent forward, with this bent end extending along the other side of the protrusion 39 . In this way, the front end side 44b of the spring member 44 is formed to slidably sandwich both side surfaces of the protrusion 39, and thereby the front end side 44b can be prevented from moving in the width direction with respect to the protrusion 39. blocked.

In the above configuration, the curtain 24 is moved forward to fully close the window opening 14, and the sliding rod 27
The operation for locking in the locking groove 43 will be explained based on FIG.

First, the sliding rod 27 is pushed forward (arrow B in the figure). When the front end of the curtain 24 approaches the position where the window opening 14 is fully closed, the sliding rod 2
7 begins to come into contact with the lower surface side of the spring member 44 (as shown by the solid line in the figure).

Then, the sliding rod 27 is moved forward against the elastic force of the spring member 44 (indicated by a chain line in the figure). At this time, the spring member 44 is rotated upward (arrow C in the figure) as the sliding rod 27 moves forward.

Further, when the sliding rod 27 is pushed forward, the sliding rod 27 comes into contact with the stopper surface 42 and is prevented from moving further forward. At this point, when the pushing force on the sliding rod 27 is weakened, the sliding rod 27 automatically moves into the locking groove 43 due to the elastic force of the spring member 44 that is about to rotate downward (arrow D in the figure). Inserted. Thereby, the curtain 24 is held so that the window opening 14 is fully closed.

Note that in order to separate the sliding rod 27 from the locking groove 43, the sliding rod 27 must be moved against the elastic force of the spring member 44.
This is done by pushing up 7.

Moreover, although the sunshade device 20 provided in the front sunroof 11 has been described above, sunshade devices having the same configuration as this sunshade device 20 are also provided in the rear sunroofs 12 and 12, respectively. However, in this device, the moving end of the curtain can move in and out in the vehicle width direction.

(Second Embodiment) FIG. 8 shows a second embodiment, and a different configuration from the first embodiment will be explained.

50 is a rail, and 51 is a spring member. The rear end side 51a of this spring member 51 is formed in a U-shape in plan view, and both ends thereof are fitted into a pair of support holes 52, 52 formed in the rail 50.

On the other hand, the front end side 51b of the spring member 51 extends forward and downward, and the free upward rotation of the front end side 51b around the center of the support hole 52 is caused by the rear end side 51a.
is prevented by contacting the bottom plate of the rail 50. Therefore, when the sliding rod 27 comes into sliding contact with the front end side 51b, the front end side 51b rotates upward due to elastic deformation.

On the other hand, after the front end side 51b of the spring member 51 extends forward and downward, the ends thereof are folded back so as to sandwich the rail 50 from the width direction and the top and bottom directions.
This restricts the upper front end side 51b from moving in the width direction of the rail 50, and also restricts vertical movement of more than a predetermined amount.

(Effect of the invention) According to this invention, a stopper surface is formed in the guide hole to prevent the sliding rod from further advancing when the curtain fully closes the window opening by advancing the curtain,
Further, a locking groove is formed in the stopper surface and in which the sliding rod is removably inserted into the receding side of the curtain, and the sliding rod is biased to fit into the locking groove. Since a spring member is provided, when the curtain is moved to fully close the window opening, the sliding rod comes into contact with the stopper surface and prevents further movement when the window opening is fully closed. . At this point, when the force for moving the curtain is weakened, the sliding rod is automatically fitted into the locking groove formed so as to be continuous with this stopper surface due to the elastic force of the spring member. Then, the sliding rod is held in this state, thereby completing the operation of the curtain to fully close the window opening.

Therefore, there is no need for complicated operations such as manually fitting the sliding rod into the locking groove when fully closing the window opening as in the past. The operation of the curtain becomes easy. Furthermore, since the locking groove is formed on the lower surface side of the guide hole, the sliding rod fitted into the locking groove is maintained in the fitted state not only by the elastic force of the spring member but also by its own weight. It will be.

Therefore, even if the biasing force of the spring member is not too large, it is possible to prevent the sliding rod from accidentally coming off the locking groove due to vibrations while the car is running, and releasing the fully closed state. Ru.

Furthermore, when opening the window opening, the operation of disengaging the sliding rod from the locking groove requires simply pushing the sliding rod up against the elastic force of the spring member. Therefore, the detachment operation described above can be performed extremely easily.

Moreover, as described above, the present invention achieves various effects as described above by combining the sliding rod, the guide hole, the stopper surface, the locking groove, and the spring member, but since these do not have movable members, the structure It has the practical effect of being extremely simple.
