[0015]
As shown in FIG. 3, the guide rail 9 has a crank-shaped cross section in which a vertical wall 15 rises vertically from a substantially horizontal base portion 13 and a flange portion 17 extends further to the side. 13 is provided with left and right rail portions 21 having cable guide grooves 19. Between the rail part 21 and the vertical wall 15, it becomes the collar part 23 which guide | induces rainwater etc. in a drain hole.
[0016]
As shown in FIG. 4, the lid 5 is attached to a bracket 29 supported by a front moving shoe 25 and a rear moving shoe 27 that can slide back and forth between the rail portions 21 and 21 of the guide rail 9. The moving shoe 25 is for support. The rear moving shoe 27 has an elevating arm 31, and the arm pins 31 a and 31 b before and after the elevating arm 31 slide in the left and right guide grooves 33 and 34 to move the rear end side of the lid 5 up and down. In other words, it has an elevating function for so-called tilt-up and tilt-down, and is used for driving that is slidably controlled back and forth by a geared cable 35 that runs in the cable guide groove 19 of the rail portion 21.
[0017]
The geared cable 35 is controlled by a drive motor M that can be rotated forward and backward by a hand switch.
[0018]
On the other hand, the shielding device 7 includes a winding device 37 and a shield 39, and the winding device 37 is supported at both ends by a fixing member 41 provided on the guide rail 9.
[0019]
The shield 39 is always wound around a winding drum (not shown) of the winding device 37 urged in the winding direction, and can be pulled out freely. The winding device 37 is locked at the stop position when the shield 39 is slowly pulled out at the position where the shield 39 is pulled out by a predetermined amount, and is locked when the shield 39 is pulled forward again from the stop position. It is to be released.
[0020]
As shown in FIGS. 1 and 2, the front end portion of the shield 39 is provided with a rigid body such as a rod inside, and serves as an operation portion 43 for manual operation.
[0021]
Both end portions of the shield 39 have upper and lower engaging holes 45 provided at predetermined intervals, and are guided by rail grooves 47a of a second guide rail 47 formed in a C-shaped cross section. , Slide movement is possible.
[0022]
The second guide rail 47 is made separately from the guide rail 9 for the lid, and has an engaging protrusion 49 that is detachably engaged with the engaging hole 45 inside. A rack 51 is arranged. The second guide rail 47 includes a substantially horizontal engagement region L1 where the engagement protrusions 49 and the engagement holes 45 of the rack 51 are engaged, and a standby region L2 bent from the engagement region L1 into a hairpin shape. The engagement region L1 is fixedly supported by the base portion 13 of the guide rail 9.
[0023]
The rack 51 is made of a flexible material, and the front end portion thereof is integrally fixed to both sides of the front end side serving as the operation portion 43 of the shield body 39, and the rack 51 and the front end portions of the shield body 39.
