When it is moved inward (center side of the roof shades 27B, 27C), the release protrusion 41 is engaged with the engaging portion 42 of the connecting hook 30 via the inclined surface 41a. Thereby, as shown in FIG. 8, the connecting hook 30 is elastically deformed upward and released from the connected state with respect to the connecting recess 31. And by this cancellation | release of connection, each roof shade 27A-27C is opened and closed independently.

Next, the operation of the sunroof device configured as described above will be described.
In the state shown in FIGS. 3 and 10A, the three roof shades 27A, 27B, and 27C are coupled by the engagement of the coupling hook 30 and the coupling recess 31 of the coupling mechanism 29, so that the entire opening 25 is formed. It is arranged in the fully closed position that closes. In this state, both width ends of the roof shades 27A to 27C are elastically sandwiched between the upper and lower inner surfaces 26a of the guide rail 26, and the roof shades 27A to 27C are held at predetermined closed positions. For this reason, there is no fear that the roof shades 27A to 27C are moved from the closed position toward the storage position on the storage chamber 28 side by the vibration of the vehicle, and this closed state is maintained.

  When the roof shades 27A to 27C are moved from this closed state to switch to the fully opened position of the opening 25, the operation shade 32 of the roof shade 27A on the front end side is moved to the rear side of the vehicle. ˜27C are integrally moved along the guide rail 26 toward the storage chamber 28 in a connected state. Thereafter, as shown in FIG. 10B, when the roof shade 27C on the rear end side reaches the accommodation position in the accommodation chamber 28 and the movement is stopped by contact with the rear inner wall surface of the accommodation chamber 28. With the subsequent movement of the front-side roof shades 27A and 27B, the rear-side roof shade 27C is lifted by the sliding guide action of the inclined cam surfaces 33 and 34 between the roof shades 27B and 27C. As a result, as shown in FIG. 10C, the connecting hook 30 of the connecting mechanism 29 between the roof shades 27B and 27C is released from the connected state with respect to the connecting recess 31, and the subsequent central roof shade 27B is accommodated. In the chamber 28, the roof shade 27C enters the lower side of the rear end side roof shade 27C and is accommodated in a state of overlapping with the roof shade 27C.

  Further, when the roof shade 27A on the front end side is moved to the accommodation chamber 28 side, the roof shade 27A, with the central roof shade 27B being stopped by engagement with the rear inner wall surface of the accommodation chamber 28, By the sliding guide action of the inclined cam surfaces 33, 34 between 27B, the roof shades 27B, 27C on the center and rear end sides are lifted in a stacked state. As a result, as shown in FIG. 10 (d), the connecting mechanism 29 between the roof shades 27A and 27B is released from the connected state, and the front-end roof shade 27A enters the lower side of the central roof shade 27B. Thus, the roof shades 27B and 27C are accommodated in an overlapping state. In this case, the operation knob 32 on the roof shade 27A on the front end side comes into contact with the lower end edge of the opening of the storage chamber 28, and the portion of the operation knob 32 protrudes from the storage chamber 28 when the roof shade 27A on the front end side is in the storage position. Is held in the state.

  As described above, when the opening 25 is switched from the fully closed position to the fully opened position, only the front-end roof shade 27A is moved and operated without moving the roof shades 27A to 27C separately. The roof shades 27A to 27C can be moved integrally in a connected state. Accordingly, the operation of moving the roof shades 27A to 27C from the fully closed position to the fully open position can be easily performed. Further, when the roof shades 27A to 27C are sequentially moved to the storage positions in the storage chamber 28, the connection mechanism 29 is connected between the adjacent roof shades 27A to 27C by the guide action of the inclined cam surfaces 33 and 34. Is released from. For this reason, it is not necessary to manually release the connection between the roof shades 27A to 27C, and the operation of moving the roof shades 27A to 27C to the fully open position can be performed more easily.

  Moreover, since the three roof shades 27A to 27C are accommodated in a state of being vertically stacked in the accommodation chamber 28, it is not necessary to secure a large accommodation space as the accommodation chamber 28, and the roof shades 27A to 27C are provided. Can be accommodated compactly in a small space accommodating chamber 28 corresponding to one roof shade.

  On the other hand, when the opening 25 is switched from the fully open position to the fully closed position, as shown by an arrow in FIG. 10D, when the front-end roof shade 27A is pulled forward from the storage chamber 28, the roof shades 27A and 27B are drawn. Through the sliding contact of the inclined cam surfaces 33 and 34 therebetween, the roof shades 27 </ b> B and 27 </ b> C on the center portion and the rear end side are lowered in a stacked state in the storage chamber 28. Accordingly, as shown in FIG. 10C, the connection hook 30 of the connection mechanism 29 is shifted to the connection state with respect to the connection recess 31 between the roof shades 27A and 27B on the front end side and the central portion, and the roof shades 27A 27B are pulled out and moved together.

  When the roof shade 27B at the center part comes out from below the roof shade 27C at the rear end side, the roof shade 27C at the rear end side is slid through the sliding contact of the inclined cam surfaces 33 and 34 between the roof shades 27B and 27C. Is lowered in the storage chamber 28. As a result, as shown in FIG. 10 (b), the connection mechanism 29 is shifted to the connected state between the roof shades 27B and 27C on the central portion and the rear end side, and the three roof shades 27A to 27C are integrally formed. As shown in FIG. 10A, the drawer 25 is moved to be placed at the fully closed position of the opening 25.

  As described above, when the roof shades 27A to 27C are switched from the fully open position to the fully closed position, the connecting mechanism 29 is shifted to the connected state by the lowering of the roof shades 27B and 27C between the roof shades 27A to 27C. For this reason, the three roof shades 27A to 27C are connected by pulling out only the roof shade 27A on the front end side from the storage position in the storage chamber 28 without separately moving the roof shades 27A to 27C. The state can be pulled out and moved in order. Therefore, the operation of moving the roof shades 27A to 27C to the fully closed position can be easily performed.

  Next, when the roof shades 27A to 27C are opened and closed independently, as shown in FIGS. 6 and 7, the operation knobs 40 of both release levers 38 of the release mechanism 35 in the desired roof shades 27B and 27C are set. When the gripping operation (in the direction of the arrow) is performed, the release levers 38 are moved inward against the urging force of the wire spring 43. As a result, as shown in FIG. 8, the release protrusions 41 on the release levers 38 are engaged with the engaging portions 42 of the connection hooks 30, and the connection hooks 30 are elastically deformed upward to form connection recesses. 31 is released from the connected state. Thus, the desired roof shades 27A to 27C can be disconnected, and the desired roof shades 27A to 27C can be individually operated by moving the operation knob 32, the operation knob 40, or the like in the released state. Can be easily opened and closed.

  As described above, in the sunroof device 22, the three roof shades 27 </ b> A to 27 </ b> C can be integrally opened / closed in a connected state, or can be opened / closed independently after being released from the connected state. Can do. Therefore, when the roof shades 27A to 27C are integrally opened and closed in the connected state, the opening 25 can be easily switched between the fully open state and the fully closed state as shown in FIG. 9A. Further, as shown in FIG. 9B, when the roof shade 27 </ b> C on the rear end side is accommodated in the accommodation chamber 28 in a state where the roof shades 27 </ b> A to 27 </ b> C are connected, the vehicle front side portion of the opening 25 is It can also be placed in an open state.

  Moreover, by releasing the adjacent roof shades 27 </ b> A to 27 </ b> C from the connected state and independently opening and closing the roof shades 27 </ b> A to 27 </ b> C, the roof shades 27 </ b> A to 27 </ b> C can be easily disposed in a partially open state at an arbitrary position of the opening 25. . For example, as shown in FIG. 9 (b), by accommodating the roof shade 27C on the rear end side in the accommodation chamber 28 with the connection between the roof shades 27B and 27C on the intermediate part and the rear end side released, Only the vehicle rear side portion of the opening 25 can be opened.

  Further, as shown in FIG. 9 (c), the roof shade 27C on the rear end side is accommodated in the accommodation chamber 28 in a state in which the connection between the roof shades 27A and 27B of the front part and the intermediate part is released, thereby opening the opening. Only the middle part in the vehicle longitudinal direction of 25 can be opened. Further, as shown in FIG. 9C, the roof shades 27B and 27C on the intermediate and rear end sides are accommodated in the accommodation chamber 28 in a state in which the connection between the front and intermediate roof shades 27A and 27B is released. By doing so, the vehicle front side portion and the rear side portion of the opening 25 can be opened.

  Moreover, in this embodiment, since the two sunroof devices 22 are juxtaposed in the vehicle width direction so that the opening and closing direction of the roof shades 27A to 27C is the front-rear direction of the vehicle, The shades 27A to 27C can be arranged in different open / close states. Therefore, for example, in a vehicle equipped with three rows of seats in the front-rear direction, as shown in FIGS. 9A to 9C, the occupant seated in each seat has the desired roof shades 27A to 27C. It can be set and arranged freely in the open / closed state. In other words, since the open / closed state of the left and right sunroof devices 22 can be freely selected, the passenger in the left or right seat can freely select the open / closed state regardless of the right adjacent or left adjacent seat. Further, since the roof shades 27A to 27C can be freely opened and closed individually or in a connected state, the passengers in the front, center, and rear seats can freely select the open / closed state regardless of the front and rear seats. Therefore, as a result, each passenger can open and close the roof according to his / her intentions without causing any other trouble, and comfort can be improved.

As described above, this embodiment exhibits the effects listed below.
(1) When the opening 25 is switched from the fully closed position to the fully open position, or from the fully open position to the fully closed position, only the roof shade 27A on the front end side is moved without separately moving the roof shades 27A to 27C. A moving operation may be performed, and the moving operation can be performed very easily.

  (2) Since the three roof shades 27 </ b> A to 27 </ b> C are accommodated in a state of being vertically stacked in the accommodation chamber 28, it is not necessary to secure a large space as the accommodation chamber 28. For easy layout. Moreover, since a large area is not required for the storage chamber 28, the area of the opening 25 can be increased as a result, and the feeling of opening can be improved.

  (3) The roof shades 27A to 27C of the sunroof device 22 arranged side by side can be easily opened and closed independently, so that the driver and passengers can not only fully open and close, but can be partially opened and closed at arbitrary positions. Since partial closure can be selected, comfort can be improved.

  (4) The roof shades 27A to 27C are easily switched to the connected state and the released state with the movement by the guide action of the cam surfaces 33 and 34 formed on the opposed end surfaces of the adjacent roof shades 27A to 27C. Therefore, the connection can be released without providing a dedicated part, and the configuration can be simplified.

  (5) Using the elasticity of the guide rail 26, the roof shades 27 </ b> A to 27 </ b> C can be held in any closed position in the opening 25. Therefore, a dedicated part for holding the roof shades 27A to 27C is unnecessary, and the configuration is simple.
