[0062]
Next, the operation of this embodiment will be described. As apparent from FIG. 3, the hinge shaft 54 for attaching the front end portion of the side bar 18 to the vehicle body is inclined downward at an inclination angle θ, so that the side bar 18 is always Tilt outwards.
[0063]
For this reason, when the support shaft 54 is horizontal and the lifted state is upright, it becomes easy to rattle from side to side. However, by tilting the support shaft 54, the side bar 18 is constantly inclined, and this inclination is the side bar. Since 18 is a relatively heavy object, it is stable, so that the backlash of the hinge portion is accommodated on the outside and the backlash is less likely to occur.
[0064]
In addition, even when the left and right side bars 18 are curved so that the rear interval is narrowed, the tip of the side bar 18 is less likely to come into contact with the roof panel 45 when lifting. Therefore, it can be applied to a vehicle body design in which the vehicle width at the rear of the vehicle body is narrowed, and the roof panel 45 can be made relatively wide.
[0065]
In addition, the distance between the tip of the side bar 18 and the roof panel 45 can be arbitrarily adjusted by setting the inclination angle θ of the support shaft 54.
[0066]
Further, since the hinge brackets 55 and 56 are fastened together with the mounting stay 58 provided in the vicinity of the lower end portion of the roof pillar 40 to the vehicle body side mounting seat 59, the hinge mounting portion is provided on the roof pillar 40 which is a rigid member. Since the rigidity of the mounting stay 58 can be used, the rigidity of the mounting portion can be ensured and it is advantageous in the mounting work of each member.
[0067]
At this time, since the support shaft 54 is located at the upper part of the mounting stay 58, the side bar 18 is less overlapped with the front part of the vehicle body when lifting, and the side of the support shaft 54 when the position of the support shaft 54 is lowered. The trouble of securing the swing locus of the upper front end of the bar on the front side of the vehicle body is eliminated, and the degree of freedom in designing the vehicle body is increased.
[0068]
In addition, since the damper member 62 for connecting the hinge bracket 56 and the side bar 18 is provided, when the side bar 18 is lifted, it can be lifted smoothly without surrendering a shock to the hinge portion. For this reason, the durability of the mounting portion with respect to the vehicle body side can be enhanced, and the damper member 62 serves as a stopper for raising the splash.
[0069]
Furthermore, the side bar 18 is a box-shaped cover member 51, 52 that covers the rod-shaped core member 50 and the locking mechanism attached thereto, so that these mechanical parts can be efficiently stored and the appearance can be improved. improves.
[0070]
Further, when the side bar 18 is lifted, the side bar 18 is substantially parallel to the front portion of the roof pillar 40 in a side view at the stop position, so that a sense of unity with the vehicle body is obtained, and the appearance is further improved. Even if the parking is done with a lift, there is no sense of incongruity and it is suitable for the characteristics of a small vehicle.
