When the rear slider 12R moves to the rearmost position, the guide rail 7 has a notch 62 into which the downward projection 59a of the timing rod 59 and the locking portion 61 enter, and a locked portion 63 formed on the lower side of the rail. Further, an elastic member 64 for elastically pressing the timing rod 59 downward is formed on the upper side of the rail. The resilient means 64 is configured to repel an arc-shaped resilient body 65 with a spring 66. The timing rod 59 is lifted by the vibration of the vehicle body, and the downward projecting portion 59a and the locking portion 6 are lifted.
1 is elastically prevented from unintentionally detaching from the guide rail 7.

When the downward projection 59a and the locking portion 61 enter the notch 62 and the locked portion 63, the straight portion 60b of the guide groove 60 becomes parallel to the guide rail 7, and the pin portion 21B is moved from the downward groove portion 60a. It enters the straight portion 60b and becomes slidable backward. Therefore, the rearward movement of the front slider 12F is not transmitted to the rear slider 12R.

This is a front slider independent moving means 68 that allows the above.

Also in the rear opening and closing device 8R, the tilt fulcrum of the rear cover member 6R is arranged behind the front end, but the rear cover member
Since the 6R performs an overall ascending operation in which the front portion also rises during the tilting operation, both sides of the front portion do not fall below the upper surface of the mounting frame 3.

The tilt opening / closing operation of the rear opening / closing device 8R starts from the closed state shown by the solid line in FIGS. 3 and 9 in synchronization with the tilt raising operation of the front cover member 6F.

When the front slider 12F starts moving backward, the timing rod 59 is moved backward via the pin portion 21B of the connecting plate 20, and
The rear slider 12R is moved by being pushed by the timing rod 59, and the lifter 10R, that is, the rear cover member 6R is entirely raised while being tilted up via the cam groove 40 and the cam pin 41.

When the front and rear sliders 12F and 12R further move rearward after the front and rear cover members 6F and 6R are almost completely raised, the cam portion 42 rotates the position setting member 22R rearward and downward through the cam groove 43, and the engagement portion 44 is disengaged from the engaged portion 45.

Thereafter, the rear slider 12R moves rearward with the rear lifter 10R, whereby the front and rear cover members 6F, 6R move together to the rear of the opening 2 while keeping the front and rear cover members parallel in the tilt-up posture, and open the opening 2. I do.

When the rear cover member 6R reaches the rear portion of the opening 2, the timing rod 59 is resiliently pressed down by the resilient means 64 (FIG. 9C). As a result, the rearward movement of the rear cover member 6R is stopped. Thereafter, the forward movement of the front slider 12F continues, and only the front cover member 6F independently moves backward until the pin portion 21B reaches the rear end of the straight portion 60b of the guide groove 60.

The closing operation of the rear cover member 6R is performed by the forward movement of the front slider 12F, whereby the pin portion 21B enters the downward groove 60a, lifts the front portion of the timing rod 59 against the elastic member 64, and the locking portion 61 It starts after detaching from the locked portion 63.

Note that the present invention is not limited to the above embodiment,
Various modifications can be made. For example, if the cover member 6 is 3
It is possible to increase the number of sheets, to form the spring means 64 with a leaf spring, to use the own weight of the timing rod 59, and to provide the pin portions 20A and 20B on the front slider 12F without providing the connecting plate 20. Instead of providing the locking portion 61 and the locked portion 63, the downward projection 59a and the notch 62 may be used as the locking portion and the locked portion, respectively.

(Effects of the Invention) According to the present invention described in detail above, since the front slider that is driven back and forth and the rear slider that is driven are connected by the timing rod, the positioning of the front and rear cover members is extremely easily and accurately performed. When the rear slider reaches the rearmost position, the position is fixed to the guide rail by the position fixing means, so that the rearmost position of the rear cover member can be accurately set, and the rearmost position of the rear cover member can be set. After the setting, only the front cover member is moved, so that the driving becomes light. Further, the structure for simultaneously moving the plurality of cover members up and down, moving backward and independently moving the front cover is simple, and the production and assembly can be facilitated.

Further, a timing rod is provided between the front slider and the rear slider that is driven back and forth to transmit the front / rear movement of the front slider to the rear slider, and the rear slider is located between the timing rod and the guide rail at the rearmost position. Since the timing slider has a position fixing means for locking the timing rod to the guide rail so as to be detachably engaged with the guide rail to fix the relative position, and a biasing means for biasing the timing rod in the locking direction, the rear slider can be moved. When moving to the rearmost position and locking the timing rod to the guide rail in a detachable manner, the timing rod can be urged in the locking direction by the urging means, and the timing rod can be securely locked. In addition, even if there is a vibration or the like, it is possible to prevent unintentional detachment.
