A weather strip 49 is attached to an opening portion extending from the rear end of the rear roof rail 13 to the rear end of the rear pillar 12, and extends from the upper edge of the front end to the side edge of the front end when the rear window 37 is closed. The outer peripheral edge of the window sash 42 is tightly pressed. Similarly, a weather strip 50, which is tightly pressed against the upper edge of the waist molding 40 when the rear window 37 is closed, is attached to the lower edge of the window sash 42. It is designed to ensure airtightness.

On the other hand, as shown in FIG. 2, FIG. 5, FIG. 7, FIG. 8, and FIG. 11, a forward and reverse synchronous drive motor for opening and closing the rear window 37 is provided under the left and right rear quarter panels 11. A pair of left and right body plates 53, each of which is assembled with 52 and a non-reciprocal transmission mechanism (not shown), are screwed to the body plate 53. It is pivotally attached via 55. The non-reciprocal transmission mechanism in the present embodiment is composed of a worm (not shown) integrally fitted to a rotary shaft (not shown) of the synchronous drive motor 52, and a worm wheel (not shown) meshing with the worm. The worm wheel is rotatably mounted in a gear case 56 integrally fixed to the body plate 53, and the drive pinion 57 coaxially integrated with the worm wheel swings the swing arm 54. Circular sector gears 58, which are integrally attached to the swing arm 54 coaxially with the shaft 55, mesh with each other. Further, the tip end of the swing arm 54 and the rear end of the sash connecting arm 43 are rotatably pinned to both ends of a pair of left and right links 59, respectively, and the rear window 37 is In the closed state, the connecting position of the link 59 to the sash connecting arm 43 and the length of these links 59 are set so that the links 59 and the swinging arm 54 are vertically aligned in a substantially straight line.

Therefore, when the synchronous drive motor 52 is operated from the state shown in FIG. 11, the swing arm 54 swings clockwise around the swing shaft 55 in FIG. 11, and this swing arm 54 With the turning motion, the rear window 37 rotates counterclockwise in FIG. 11 about the pin 45, and the rear window 37 is gradually closed. As the rear window 37 approaches the fully closed state, the swing arm 54 and the link 59 approach the dead center position where they are aligned, so the rotational angular velocity of the rear window 37 via the link 59 becomes slow. Therefore, the rotational torque of the rear window 37 will gradually increase. As a result, the outer peripheral edge of the window sash 42 continuing from the front upper edge of the rear window 37 to the front side edge is strongly pressed against the weather strip 49 continuing from the rear end of the rear roof rail 13 to the rear end of the rear pillar 12. On the other hand, the weather strip 50 attached to the lower edge of the window sash 42 is strongly pressed against the upper edge of the waist molding 40, so that the inside of the cabin 51 is reliably sealed.

As described above, by setting the link 59 and the swing arm 54 so as to be substantially vertically aligned with each other in the state where the rear window 37 is closed, the rear window 37 is attached to the rear window 37 due to its own weight. The rotation moment of the swing arm 54 toward the opening side of the window 37 can be suppressed to a small value. Further, in this embodiment, the rotational moment of the swing arm 54 toward the opening side of the rear window 37 due to the weight of the rear window 37 described above is canceled and the meshing of the drive pinion 57 and the sector gear 58 described above is achieved. In order to reduce the backlash, a spiral spring 60 that urges the swing arm 54 in the direction in which the rear window 37 is closed is interposed between the body plate 53 and the swing arm 54, and depending on the rotation direction of the synchronous drive motor 52. The load of the synchronous drive motor 52 is prevented from largely changing, while the engagement state of the drive pinion 57 and the sector gear 58 is kept constant.

The synchronous drive motor 52 described above is operated in the energizing direction and its on / off state via the control unit described above based on the operation of a window opening / closing switch (not shown) provided on an instrument panel in front of the driver's seat (not shown). It can be switched off. Further, reference numeral 61 in FIG. 10 is a rear shelf which is attached to the tower connecting beam 25 through the rear shelf bracket 23, and 62 is a high mount which is attached to the center portion of the waist molding 40 in the vehicle width direction. It is a stop lamp.
