Next, the open / close structure of the roofs 4 and 5 will be described in detail with reference to FIGS.
7 is a side view when the roof is closed (closed), FIG. 8 is a side view when the roof portion RO is being opened / closed, FIG. 9 is a side view when the roof is opened (that is, when the roof is stored), and FIG. FIG. 11 is a schematic perspective view showing a roof structure.

  As shown in FIGS. 7 to 11, particularly FIG. 9, when the roof portion RO is opened and the roof portion RO is stored in the roof storage space 14, one divided portion of the roof portion RO, that is, the front A support mechanism 73 for supporting the roof portion RO on the vehicle body so as to cover the space between the occupant seat 19 and the vertical portion 13V of the rear bulkhead 13 substantially horizontally above the roof storage space 14 in the portion roof 4 is provided. Yes.

  In this embodiment, as shown in FIGS. 7, 8, and 9, the roof portion RO described above is divided into a front roof 4 and a rear roof 5, which are divided into two front and rear sides. As shown in FIG. When the portion RO is opened, the rear roof 5 is stored in the roof storage space 14, and the front roof 4 is positioned above the rear roof 5 so as to cover the roof storage space 14 from above substantially horizontally. is doing.

  Therefore, the support mechanism 73 includes a side link L-shaped lower link 73A and an upper link 73B. As shown in FIG. 11, the base portion of the lower link 73A is a support shaft 74 and a bracket 75. The free end portion of the lower link 73A is connected to the bracket 76 on the lower surface of the rear roof 5 with a pin 77 (see FIG. 4). It is supported).

  The upper link 73B is fixed to the front lower surface of the rear roof 5. As shown in FIG. 7, the upper link 73B includes an extension 73a extending from the rear roof 5 to the front roof 4 side. An end portion of the extension portion 73 a is connected (pivoted) with a pin 79 to a bracket 78 on the lower surface of the rear portion of the front roof 4.

  As shown in FIG. 11, a pair of support mechanisms 73 including a lower link 73A and an upper link 73B are provided on both the left and right side portions of the roof portion RO on the vehicle interior side, but in the drawing, only the support mechanism 73 on the right side of the vehicle is provided. It is shown.

Further, as shown in FIG. 10, between the pin 79 at the end of the upper link 73B and the bracket 78 on the front roof 4 side, the front roof 4 moves rearward while maintaining a forward tilt posture at a predetermined angle. As shown, a spring 80 is attached. By holding the front roof 4 in the forward tilted posture and allowing the vehicle to move backward, the roof RO can be manually opened without causing running wind when the vehicle moves forward at a slow speed.
Here, the length of the front roof 4 on the front side of the pin 79 when the roof is closed (when the roof is closed) shown in FIG. 7 is sufficiently longer than the length of the front roof 4 on the rear side of the pin 79. Since the front roof 4 tends to tilt forward in the weight ratio before and after the pin 79 as a fulcrum, the spring force of the spring 80 may be small.

  In this embodiment, the roof portion RO is configured to be manually opened and closed. As shown in FIG. 9 from the fully closed state of FIG. 7 to the middle state of FIG. When opened, the rear roof 5 is reversed and stored in the roof storage space 14 by the lower link 73A that rotates about the support shaft 74, and the front roof 4 moves rearward while maintaining its forward tilting posture. However, as shown in FIG. 9, it is located above the rear roof 5 so as to cover the upper part of the roof storage space 14 substantially horizontally.

  In FIG. 9, the extension 73a of the upper link 73B prevents the front roof 4 that covers the top of the roof storage space 14 from being tilted excessively by the urging force of the spring 80 (see FIG. 10). The front roof 4 is supported from the lower side, and a regulating piece 73b for preventing the front roof 4 from being excessively forwardly tilted is integrally formed. For this reason, as shown in FIG. 8, the front roof 4 moves rearward while maintaining a forward tilted posture at a predetermined angle so as not to catch the traveling wind, and as shown in FIG. The upper part of the storage space 14 can be covered substantially horizontally.

  7 to 9, reference numerals 81 and 82 denote stoppers for restricting the upper limit position and the lower limit position of the lower link 73A, and in particular, the front roof 4 and the rear roof 5 in the storage position by the lower stopper 82. And it can prevent reliably that each link 73A, 73B moves below unnecessarily.

  When the roof portion RO in the closed state shown in FIG. 7 is opened (opened) as shown in FIG. 9, first, the occupant manually operates after unlocking the roof portion RO by the top lock 83 (see FIG. 11). When the front roof 4 is moved rearward, this rearward moving force is transmitted to the lower link 73A via the upper link 73B and the rear roof 5, so that the lower link 73A is rearward and downward with the support shaft 74 as a fulcrum. That is, it rotates clockwise as shown in the figure, and the rear roof 5 is substantially raised from the front high rear low state of FIG. 7 as shown in FIG. 8, and is pivotally supported by the rear roof 5 via the upper link 73B. The front roof 4 moves backward as shown in FIG. 8 while maintaining a forward tilting posture so as not to catch the traveling wind by the urging force of the spring 80 and the weight ratio between the front and rear sides of the pin 79.

  When the front roof 4 is further moved rearward from the halfway state shown in FIG. 8, the rearward moving force is transmitted to the lower link 73A via the upper link 73B and the rear roof 5, so that the lower link 73A is supported by the lower link 73A. The shaft 74 is further pivoted downward, that is, in the clockwise direction as shown in the figure, and the rear roof 5 is in the inverted state as shown in FIG. 9 from the substantially upright state in FIG. The front roof 4 moves rearward above the inverted rear roof 5 and covers the roof storage space 14 substantially horizontally with the front roof 4. .
