By pressing against the inner edge of the wall portion 55k in the vehicle width direction to bend the claw portion 61e in the anti-projection direction and moving it to the locking hole 55v, it can be attached to the outer upper wall portion 55k.

  A U-shaped fourth notch 55e 'is formed at a position facing the second notch 55t at the leading edge of the inner upper wall portion 55e, that is, at a position closer to the front than the center in the longitudinal direction. .

  At a position slightly lower than the tip of the inner vertical wall portion 55d, an inner wall portion 55w is provided so as to project inward in the vehicle width direction, and the upper surface of the inner wall portion 55w is closer to the outside than the center in the vehicle width direction. A cover mounting portion 55x extending in the front-rear direction and having a substantially L-shaped cross-section is provided at the position so as to form a fourth groove portion G4 that opens to the inside in the vehicle width direction with the inner wall portion 55w. The cover mounting portion 55x is located on the inner side in the vehicle width direction than the lid-side first protrusion 21a and the lid-side second protrusion 21e of the hook member 21 and the shade-side protrusion 51f of the shade 13.

  The inner groove 35b of the slider 35 is engaged with the first groove G1 of the guide rail 54 configured as described above, and the inner lower wall 55b is in contact with the inner slider 35b from below. An outer slider portion 35c of the slider 35 is engaged with the third groove portion G3, and the first outer lower wall portion 55c is in contact with the outer slider portion 35c from below. The push-pull cable 37 of the slider 35 is engaged with the cable guide groove 55m.

  As shown in FIG. 15, a lower end portion of a bellows-shaped cover member 63 that can expand and contract in the vertical direction is mounted on the cover mounting portion 55x of the guide rail 54 so as to be slidable in the front-rear direction. The upper end of the cover member 63 is fixed to the sunroof lid 9.

  Next, the operation of the sunroof device 1 configured as described above will be described with reference to FIGS.

  FIG. 16A shows a state where the sunroof lid 9 is in the fully closed position and the shade 13 closes the indoor opening 7a. At this time, the engaging portion 35a of the slider 35 is engaged with the flat region R1 of the inner cam groove 19f and the outer cam groove 19j. In addition, the shoe 19q abuts against the stopper member St, thereby preventing the lid support member 19 from moving further forward. The front and rear positions of the front outer protruding piece 19n and the rear outer protruding piece 19k of the lid support member 19 match the front and rear positions of the first guide member 57 and the second guide member 59. The front outer protruding piece 19n is located in the first guide groove 57a. This also prevents the lid support member 19 from moving forward. On the other hand, the rear outer protruding piece portion 19k completely exits upward from the third groove portion G3. Further, the inner protruding piece portion 19g is completely removed upward from the second groove portion G2. In the fully closed state, the sunroof lid 9 is substantially flush with the outer surface of the roof 3. Further, the lid-side first protrusion 21a of the hook member 21 of the sunroof lid 9 and the shade-side protrusion 51f of the shade support member 51 are vertically separated from each other, and the engagement between the two is released. Therefore, the shade 13 can be moved in the front-rear direction while being separated from the sunroof lid 9. The lid-side first protrusion 21a of the hook member 21 and the shade-side protrusion 51f of the shade support member 51 are also separated in the front-rear direction.

  Next, in a state where the sunroof lid 9 is in the fully closed position and the indoor opening 7a is closed by the shade 13, the push-pull cable 37 is driven by the drive motor 39 to move the slider 35 rearward. The engagement portion 35a moves from the flat region R1 of the inner cam groove 19f and the outer cam groove 19j to the inclined region R2, and presses the inner lower wall portion 19e and the outer lower wall portion 19i rearward in the inclined region R2. At this time, since the rearward movement of the lid support member 19 is restricted by the engagement between the front outer projecting piece 19n and the first guide groove 57a, the lid support member 19 does not move rearward. On the other hand, since the rear outer protruding piece portion 19k escapes upward from the third groove portion G3 and the inner protruding piece portion 19g also escapes from the second groove portion G2, the lid supporting member 19 tilts in the vertical direction. Is not regulated. Therefore, the lid support member 19 tilts so that the rear end part descends around the shoe 19q as a fulcrum. Accordingly, the sunroof lid 9 also tilts so that the rear end part descends. Then, the front outer projecting piece 19n exits downward from the first guide groove 57a of the first guide member 57 and enters the third groove G3. Further, the rear outer protruding piece portion 19k escapes downward from the second guide groove 59a of the second guide member 59, and enters the third groove portion G3. Further, the inner protruding piece portion 19g passes through the fourth notch portion 55e 'and enters the second groove portion G2. The front outer protruding piece 19n and the rear outer protruding piece 19k abut on the first outer lower wall 55c in the third groove G3, and the inner protruding piece 19g is supported in the second groove G2 by the support wall 55f. And the sunroof lid 9 reaches the lowered position. When the slider 35 is further moved rearward from this state, the front outer protruding piece portion 19n and the rear outer protruding piece portion 19k are located in the third groove portion G3 and are moved rearward by the first guide member 57 and the second guide member 59. Is not regulated, the sunroof lid 9 moves rearward. Then, as shown in FIG. 16B, the lid-side guide surface 21c of the lid-side first protrusion 21a of the hook member 21 comes into contact with the shade-side guide surface 51g of the shade-side protrusion 51f of the shade support member 51, The shade side guide surface 51g is pressed rearward. As a result, the lid-side first protrusion 21a moves along the slope (shape) of the shade-side guide surface 51g, and gets over the shade-side protrusion 51f. When the slider 35 is further moved rearward from this state, as shown in FIG. 16C, the lid-side second protrusion 21 e of the hook member 21 is moved to the front surface of the front peripheral wall portion 51 c of the shade support member 51. It comes into contact with the lower half (non-inclined area) and presses the shade support member 51 backward. As a result, the entire shade 13 moves rearward in conjunction with the movement of the sunroof lid 9. When the slider 35 is further moved rearward in this state, the sunroof lid 9 reaches the fully open position, and the shade 13 opens the entire indoor opening 7a.

  In an open state in which the sunroof lid 9 is located on the rear side (the lid opening direction side) of the lowering position, the second outer lower wall portion 55c "of the guide rail 54 is connected to the front outer protruding piece portion 19n of the lid support member 19 and the rear. The second upper wall portion 55r of the guide rail 54 abuts on the outer protruding piece portion 19k and the rear outer protruding piece portion 19k of the lid support member 19 from above, or has a small interval. This restricts the vertical movement of the front outer protruding piece portion 19n and the rear outer protruding piece portion 19k of the lid support member 19. On the other hand, in the above open state, the guide rail 54 is supported. The wall portion 55f abuts on the inner protruding piece portion 19g of the lid support member 19 from below, and the inner upper wall portion 55e of the guide rail 54 is placed above the inner protruding piece portion 19g of the lid support member 19. In this way, the vertical movement of the inwardly protruding piece 19g of the lid support member 19 is regulated, and thus the lid support member 19 is vertically moved in the open state. Is restricted on both sides in the vehicle width direction of the lid support member 19, so that a large load acts forward on the slider 35 due to a vehicle collision or the like in the open state, and the slider 35 moves forward through the inclined region R2. Even when the sunroof lid 9 moves at a high speed and a thrust load acts on the sunroof lid 9, the lid support member 19 is unlikely to separate above the guide rail 54.

  When the push-pull cable 37 is driven by the drive motor 39 to move the slider 35 forward in a state where the sunroof lid 9 is in the fully open position and the shade 13 completely opens the indoor opening 7a, the slider 35 Is located in the inclined region R2, the engagement portion 35a presses the inner upper wall portion 19d and the outer upper wall portion 19h of the inner cam groove 19f and the outer cam groove 19j forward. At this time, the front outer protruding piece portion 19n and the rear outer protruding piece portion 19k abut on the second upper wall portion 55r in the third groove portion G3, and the lid supporting member 19 cannot further tilt upward. On the other hand, the front outer protruding piece portion 19n and the rear outer protruding piece portion 19k are located in the third groove portion G3, and are not engaged with the first guide member 57 and the second guide member 59, so that they move forward. Movement is not regulated. Therefore, the lid support member 19 moves forward along the third groove G3, and the entire sunroof lid 9 moves forward. Then, as shown in FIG. 16D, the lid-side first protrusion 21a of the hook member 21 abuts and engages with the shade-side protrusion 51f of the shade support member 51 from behind. Thus, the sunroof lid 9 and the shade 13 are connected. When the slider 35 is further moved forward in this state, the entire shade 13 moves forward in conjunction with the movement of the sunroof lid 9. Thereafter, as shown in FIG. 16 (e), the hook-side guide surface 21 f ′ of the guided piece 21 f of the hook member 21 slides on the rear inclined guide surface 61 b of the main body 61 a of the disengagement member 61. By moving along the shape of the inclined guide surface 61b, the hook member 21 is pushed upward and pivots upward around the pin insertion hole 21d, and as shown in FIG. The engagement between the first side projection 21a and the shade side projection 51f of the shade support member 51 is released, and the sunroof lid 9 and the shade 13 are separated from each other. At this time, the shade 13 is located at a position covering the entire indoor opening 7a.

  Thereafter, when the slider 35 is further moved forward, the sunroof lid 9 reaches the lowered position. At this time, the forward movement of the lid support member 19 is regulated by the contact of the shoe 19q with the stopper member St. At this time, the front outer projecting piece 19n is located below the first guide groove 57a of the first guide member 57, and the rear outer projecting piece 19k is located below the second guide groove 59a of the second guide member 59. positioned. That is, the front outer protruding piece 19n and the rear outer protruding piece 19k are in a state in which upward movement is not restricted by the second upper wall 55r. Further, the inner protruding piece 19g is in a state in which upward movement is not restricted by the inner upper wall 55e. Therefore, when the slider 35 is further moved forward, the engagement portion 35a of the slider 35 is moved forward in a state of being engaged with the inclined region R2 of the inner cam groove 19f and the outer cam groove 19j, and the lid support member 19 is moved. , With the shoe 19q as a fulcrum. As a result, the front outer projecting piece 19n enters the first guide groove 57a of the first guide member 57, and the rear outer projecting piece 19k enters the second guide groove 59a of the second guide member 59. In addition, the inner protruding piece 19g passes through the fourth cutout 55e '. Thereafter, the engagement portion 35a reaches the flat region R1 of the inner cam groove 19f and the outer cam groove 19j, and the sunroof lid 9 reaches the fully closed position. At this time, the front outer protruding piece portion 19n is located within the first guide groove 57a, and the rear outer protruding piece portion 19k is pulled upward from the second guide groove 59a. In addition, the inner protruding piece 19g comes out of the second groove G2. Further, as shown in FIG. 16A, the lid-side first protrusion 21a of the hook member 21 and the shade-side protrusion 51f of the shade support member 51 are vertically separated from each other, and the engagement between them is released. I have.

  Therefore, according to the present embodiment, the rear outer protruding piece 19k and the front outer protruding piece 19n of the lid support member 19 do not abut on the vehicle width direction outer end of the first outer lower wall 55c. When both the outer slider portion 35c of the slider 35 and the rear outer projecting piece portion 19k and the front outer projecting piece portion 19n of the lid support member 19 are brought into contact with the vehicle width direction outer end portion of the first outer lower wall portion 55c. The outer end of the first outer lower wall 55c in the vehicle width direction is less likely to be damaged. Therefore, it is possible to prevent a problem caused by damage to the outer end in the vehicle width direction of the first outer lower wall portion 55c.

  Further, since the supporting wall portion 55f that contacts the inner protruding piece portion 19g of the lid support member 19 is provided separately from the inner lower wall portion 55b that contacts the inner slider portion 35b of the slider 35, the inner slider portion of the slider 35 is provided. The inner lower wall portion 55b is less likely to be damaged as compared with a case where both 35b and the inner protruding piece portion 19g of the lid support member 19 abut against the inner lower wall portion 55b. Therefore, it is possible to prevent problems caused by damage to the inner lower wall portion 55b.

  Further, since the entire support wall portion 55f is arranged at a position vertically overlapping the inner lower wall portion 55b, the guide is smaller than a case where the support wall portion 55f and the inner lower wall portion 55b are arranged at a position not vertically overlapping. The dimension of the rail 54 in the vehicle width direction can be reduced.

  Further, the tongue piece 27e can be formed simply by cutting out and bending a part of the main surface 27a of the metal plate 27 of the lid support member 19, and a metal part for forming the tongue piece 27e is separately prepared and provided on the metal plate 27. Since it is not necessary to mount the device by welding or the like, manufacturing costs can be reduced.

  Further, since the outer surface of the inner protruding piece 19g is made of resin, it is possible to prevent the guide rail 54 from being damaged by the contact with the inner protruding piece 19g, as compared with the case where it is made of metal. Further, generation of abnormal noise due to contact between the guide rail 54 and the inner protruding piece 19g can be suppressed.

  Further, since the rigidity of the inner protruding piece 19g is increased by embedding the metal tongue piece 27e in the inner protruding piece 19g, the inner protruding piece 19g is damaged by contact with the guide rail 54. Hateful.

  In the above embodiment, the entire support wall 55f is arranged at a position vertically overlapping the inner lower wall 55b, but may be arranged at a position not overlapped vertically. Further, only a part of the support wall portion 55f in the vehicle width direction (lid width direction) may be disposed at a position vertically overlapping the inner lower wall portion 55b.

  Further, a second outer lower wall portion 55c "that comes into contact with the rear outer projecting piece portion 19k and the front outer projecting piece portion 19n from below is provided separately from the first outer lower wall portion 55c that comes into contact with the outer slider portion 35c from below. A part or the whole of the second outer lower wall portion 55c "in the vehicle width direction (lid width direction) may be arranged at a position vertically overlapping with the first outer lower wall portion 55c.
