Is exposed so that the aggregate 22a extends substantially in the transverse direction. A hook 31 is swingably supported by the aggregate 22a facing the inside of the hook case 28. The length of the hook 31 in the axial direction is substantially equal to the length of the aggregate 22a facing the inside of the hook case 28. Therefore, the hook 31 cannot move in the axial direction of the aggregate 22a. This hook 31 is the aggregate 2
2a has a flat plate-shaped operation knob 33 extending linearly from the bearing portion 32 in a radial direction. The operation knob 33 is provided on both sides as it is separated from the bearing portion 32 so as to be easily gripped by a finger. It is formed in the shape of an isosceles trapezoid that spreads out.
On the other hand, from the bearing portion 32 to the operation knob 33 and about 120
A hook portion 34 is formed extending in the radial direction at an angle of degrees, and the tip end portion of the hook portion 34 is curved outward in an arc shape. A coil spring (not shown) for urging the hook 31 in the clockwise direction in FIG. 9 is interposed between the aggregate 22a and the hook 31, and the hook 31 is always positioned as shown in FIG. It has become. Then, in order to pull out the shade body 1 from the winding section 2, the operation knob 33 is rotated counterclockwise against the coil spring in FIG. 9 to pull the shade body 1, and the hook portion 34 of the hook 31 is The hook case 28 is completely retracted.

The hook portion 34 of the hook 31 can be engaged with the holding arm 36 of the holder 35 shown in FIG. 10 when the shade body 1 is almost completely pulled out. The holder 35 is a substrate 38 fixed to an interior cover 37 in the vehicle compartment facing the central position between the tips of the guide rails 9A and 9B.
On the base plate 38, there is a U-shaped holding arm 36 whose upper part is slightly inclined toward the roof window 39.
The hook portion 34 is engaged with the horizontal arm 40 of the holding arm 36. In addition,
The roof window 39 is, for example, formed in a curved shape at the corner of the top of the vehicle body.

Next, the operation of the above-described embodiment will be described.

In the state where the roof window 39 of the sunroof is opened, the shade body 1 is wound around the winding shaft 6 of the winding portion 2 by a coil spring (not shown), so that the entire shade body 1 is wound. 2 on each side
Rollers 24, 24 ... Protrudingly provided at both ends of 2a, 22b are fitted to the guide rails 9A, 9B. In order to withdraw the shade body 1 from such a state and block the light introduced from the roof window 39 into the passenger compartment, the operation knob 33 of the hook 31 of the shade body 1 is taken with a finger and both guide rails 9A and 9B are pulled. The coil spring of the winding unit 2 is pulled to the tip of the coil. Then, the small diameter portions 26 of the rollers 24 of the two aggregates 22a and 22b roll on one edge of the slit 15 of the guide wall 14 of each of the guide rails 9A and 9B so that the rollers of each guide rail 9A and 9B are rolled. 24 is guided, and the shade main body 1 is gradually pulled out. that time,
If the force of the finger acting on the operation knob 33 of the hook 31 does not act evenly on the left and right of the shade body 1, the tip of the shade body 1 will be inclined with respect to the width direction of the guide rails 9A and 9B, and the shade will be shaded. Although it becomes difficult for the main body 1 to move, if the tip portion of the shade main body 1 is inclined in this manner, one roller 24 of one aggregate 22a or 22b and the other side of the other aggregate 22b or 22a are It is possible to prevent the stepped portions 27 of the positioned rollers 24 from coming into contact with the guide walls 14 of the guide rails 9A and 9B and largely inclining the shade body 1. Therefore, the shade body 1 can be stably run.

When the shade body 1 is pulled out as described above and the tip of the shade body 1 reaches the tip side of the curved portions 23A, 23B of the guide rails 9A, 9B, both aggregates 22a, 22b of the shade body 1 are curved. Since the end portions of the shade main body 1 are located almost at the ends of the portions 23A and 23B, the tip end portion of the shade body 1 is located in a flat shape between the ends of the curved portions 23A and 23B and the curved portions 23A and 2 of the guide rails 9A and 9B.
The shade main body 1 behind the aggregate 22b is located inside the straight portions of both guide rails 9A and 9B, although it is slightly disengaged from between 3B, so that both guide rails 9A and 9B and the shade main body 1 are separated from each other. There is no possibility that external light will leak into the vehicle interior due to the formation of the gap. After that, when the shade body 1 is further pulled out, the tip end side of the roller 24 of the shade body 1 is guided by the guide surfaces 20 of the stoppers 16A and 16B.
As it rides on the rail 20, the guide rails 9A and 9B are obliquely projected outward so as to be close to the roof window 39, and the tip of the shade body 1 is joined to the roof window 39. At that time, since the tip of the shade main body 1 is subjected to flocking processing, no collision noise is generated even if it is joined to the roof window 39. Then, in this state, the rollers 24, 24 of the aggregate 22a on the tip side contact the shade body 1 of the sleeve 19 of the stoppers 16A, 16B, and the shade body 1 is stopped. Since the tip edge of the shade body 1 is formed in an inclined shape according to the difference in length between the guide rails 9A and 9B, the tip of the shade body 1 is guided by the guide surfaces 20, 2 of the stoppers 16A, 16B.
It can be bonded to 0 at the same time. Therefore, the hook 31
When the hand is released from the operation knob 33, the hook 31 is rotated by the action of the spring and the hook portion 34 of the hook 31 is moved to the holder 3.
5, the shade body 1 can completely block light from the roof window 39 from entering the vehicle interior.

On the other hand, in order to open the roof window 39 covered by the shade body 1, the operation knob 33 of the hook 31 is taken with a finger, and the hook 31 is rotated against the spring, and the holder 35 of the hook portion 34 is The engagement with the horizontal arm 40 is released. Then, the shade body 1 is pulled in the direction of the winding portion 2 by the action of the coil spring (not shown) provided in the winding portion 2, and both aggregates 2 of the shade body 1 are pulled.
The small-diameter portions 26 of the rollers 24 projecting from both ends of the shades 2a and 22b roll along one edge of the slit 15 of the guide wall 14 of both guide rails 9A and 9B, so that the shade body 1 is almost covered. The entire length is wound on the winding shaft 6 of the winding unit 2.

As described above, according to this embodiment, since the plurality of rollers 24 having the special shape are guided so as to roll along the guide rails 9A and 9B having the special shape, the shade body 1 can be stably run. It can be performed, and there is no fear that the shade body 1 will stop halfway. In addition, the stopper 16
Since flocking processing is applied to the outer circumferences of A and 16B and each roller 24, the large-diameter portion 25 of the roller 24 is attached to the guide rail 9
Even if the guide walls 14 of A and 9B collide with each other or the tip of the shade body 1 collides with the guide surface 20 of the stoppers 16A and 16B, no noise is generated. Further, at the tip of the shade body 1, two aggregates 22a,
22b are arranged at intervals, and each aggregate 22a,
Since the rollers 24, 24 are supported at both ends of the shade body 22b, it is possible to avoid a situation in which the tip of the shade body 1 is inclined, and not only can the shade body 1 run stably, but also the guide rails 9A, 9B. The curved portion 23A at the tip of the
Even if 23B is formed, there is no possibility that the entire shade body 1 will become flat as it is disengaged from the inside of the guide rails 9A and 9B, and that the entry of external light is allowed. In addition, both aggregates 22a and 22b are provided with the guide rail 9
The aggregate 22a is inclined so that the tip edge of the shade body 1 is also inclined so as to correspond to the difference in length between A and 9B, and the tip portion of the shade body 1 is provided with the guide surface 20 of each of the stoppers 16A and 16B. , 20 and abuts on the roof window 39 to stop, so there is no risk of light entering from the tip side of the shade body 1 when the shade body 1 covers the roof window 39. Furthermore, the hook 31 for engaging and stopping the horizontal arm 40 of the holder 35 when the shade body 1 is covered with the roof window 39 also serves as the operation knob 33, and one is provided at the central portion in the width direction of the shade body 1. Since it is formed only, it is easy to handle, and it is easy to visually check the engagement / disengagement of the holder 35 with respect to the horizontal arm 40.
