FIG. 16(a) shows a state in which the sunroof lid 9 is in the fully closed position and the interior opening 7a is closed by the shade 13. FIG. 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. Further, the shoe 19q abuts against the stopper member St, thereby preventing the lid support member 19 from moving further forward. In addition, the longitudinal positions of the front outer protruding piece 19n and the rear outer protruding piece 19k of the lid supporting member 19 match the longitudinal positions of the first guide member 57 and the second guide member 59, respectively. The front outer protruding piece 19n is located inside 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 19k completely protrudes upward from the third groove G3. In addition, the inner protruding piece 19g completely protrudes upward from the second groove G2. In the fully closed state, the sunroof lid 9 is substantially flush with the outer surface of the roof 3 . Also, the first lid-side 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 them is released. Therefore, the shade 13 can be moved in the front-rear direction while being separated from the sunroof lid 9 . The first lid-side protrusion 21a of the hook member 21 and the shade-side protrusion 51f of the shade support member 51 are also spaced apart in the front-rear direction.

Next, when the sunroof lid 9 is in the fully closed position and the interior opening 7a is closed by the shade 13, the drive motor 39 drives the push-pull cable 37 to move the slider 35 rearward. The engaging portion 35a of 35 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, 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, so that the lid support member 19 does not move rearward. On the other hand, the rear outer protruding piece 19k protrudes upward from the third groove G3, and the inner protruding piece 19g protrudes from the second groove G2. is not regulated. Therefore, the lid support member 19 tilts with the shoe 19q as a fulcrum so that the rear end portion thereof descends. Along with this, the sunroof lid 9 also tilts so that the rear end portion thereof descends. Then, the front outer protruding 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 exits 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 19g passes through the fourth notch 55e' and enters the second groove G2. The front outer protruding piece 19n and the rear outer protruding piece 19k contact the first outer lower wall 55c in the third groove G3, and the inner protruding piece 19g contacts the support wall 55f in the second groove G2. 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 19n and the rear outer protruding piece 19k are positioned in the third groove G3, and the first guide member 57 and the second guide member 59 move rearward. Since the movement of the sunroof lid 9 is not restricted, the sunroof lid 9 moves rearward. Then, as shown in FIG. 16B, the lid-side guide surface 21c of the first lid-side protrusion 21a of the hook member 21 abuts 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 pushed backward. As a result, the first lid-side protrusion 21a moves along the inclination (shape) of the shade-side guide surface 51g, thereby getting over the shade-side protrusion 51f. When the slider 35 is further moved rearward from this state, as shown in FIG. It abuts on the lower half portion (non-inclined region) and presses the shade support member 51 rearward. As a result, the entire shade 13 moves rearward in conjunction with the movement of the sunroof lid 9 . In this state, when the slider 35 is moved further rearward, the sunroof lid 9 reaches the fully open position and the shade 13 opens the entire interior opening 7a.

In the open state in which the sunroof lid 9 is located on the rear side (in the lid opening direction side) of the lowered position, the second outer lower wall portion 55c″ of the guide rail 54 is positioned between the front outer protruding piece portion 19n of the lid support member 19 and the rearward outer protrusion portion 19n. The second upper wall portion 55r of the guide rail 54 contacts the front outer projecting piece 19n and the rear outer projecting piece 19k of the lid support member 19 from above or is in contact with the rear outer projecting piece 19k from above. This restricts the vertical movement of the front outer protruding piece 19n and the rear outer protruding piece 19k of the lid support member 19. On the other hand, in the open state, the guide rail 54 is supported. The wall portion 55f contacts 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 contacts the inner protruding piece portion 19g of the lid support member 19 from above. This restricts the vertical movement of the inner protruding piece 19g of the lid support member 19. In this manner, the lid support member 19 is prevented from moving vertically in the open state. Since the lid support member 19 is regulated on both sides in the vehicle width direction, a large forward load acts on the slider 35 due to a vehicle collision or the like in the open state, and the slider 35 moves forward at high speed in the inclined region R2. Even if a push-up load acts on the sunroof lid 9, the lid support member 19 is less likely to come off above the guide rails 54. - 特許庁

When the sunroof lid 9 is in the fully open position and the entire indoor opening 7a is opened by the shade 13, the drive motor 39 drives the push-pull cable 37 to move the slider 35 forward. is in the inclined region R2, the engaging portion 35a presses forward 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.

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. 16(d), the first lid-side protrusion 21a of the hook member 21 contacts and engages the shade-side protrusion 51f of the shade support member 51 from behind. As a result, the sunroof lid 9 and the shade 13 are connected, and 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 21f' of the guided piece portion 21f of the hook member 21 is slidably contacted with the inclined guide surface 61b on the rear side of the body portion 61a of the disengagement member 61. By moving along the shape of the inclined guide surface 61b, the hook member 21 is pushed upward and rotated upward around the pin insertion hole 21d, and as shown in FIG. The engagement between the side first protrusion 21a and the shade side protrusion 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 positioned to cover the entire interior opening 7a.

After that, when the slider 35 is moved further forward, the sunroof lid 9 reaches the lowered position. At this time, the forward movement of the lid support member 19 is restricted by the contact of the shoe 19q with the stopper member St. At this time, the front outer protruding piece 19n is positioned below the first guide groove 57a of the first guide member 57, and the rear outer protruding piece 19k is positioned below the second guide groove 59a of the second guide member 59. positioned. That is, the upward movement of the front outer protruding piece portion 19n and the rear outer protruding piece portion 19k is not restricted by the second upper wall portion 55r. Further, the upward movement of the inner protruding piece 19g is not restricted by the inner upper wall portion 55e. Therefore, when the slider 35 is moved further forward, the engaging portion 35a of the slider 35 moves forward while 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 forward. , with the shoe 19q as a fulcrum, and the rear end thereof tilts upward. As a result, the front outer protruding piece 19n enters the first guide groove 57a of the first guide member 57, the rear outer protruding piece 19k enters the second guide groove 59a of the second guide member 59, and In addition, the inner projecting piece portion 19g passes through the inside of the fourth notch portion 55e'. After that, the engaging 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 19n is positioned within the first guide groove 57a, and the rear outer protruding piece 19k is protruding upward from the second guide groove 59a. In addition, the inner protruding piece 19g protrudes from the second groove G2.
