Are formed. A fastener member 40 is provided above the window 39 over substantially the entire length of the tent member 31, so that the tent member 31 can be opened as necessary. FIG. 7 shows a state in which the bed 41 is laid on the central opening 7 of the roof body 2. Bed 41
Is laid on the opening 7 after the elevating roof 3 is raised with respect to the roof body 2 and is in a fully opened state. Alternatively, it may be laid on the opening 7 from the beginning. 3 beds 41
It is preferably divided or folded in three stages.

Next, referring to FIG. 8, the open / close state of the elevating roof 3 accompanying the movement of the link member 4 will be briefly described. When it is not necessary to open the elevating roof 3 while the vehicle 1 is traveling, the roller 16 attached to the lower end of the link member 4 is located at the lowermost end of the guide rail 9 (that is, the rearmost side of the vehicle 1). X1, and in this state, as shown by the chain line in FIG. 8, the link member 4 is in a lying state, and the elevating roof 3 is also in a state of being closed with respect to the roof body 2. When the vehicle 1 is stopped and it is necessary to open the lift roof 3, the motor 19 is normally rotated. The forward rotation of the motor 19 causes the roller 16 to start rolling along the rail 15 toward the front of the vehicle. As a result, the roller 17 supported at any one point of the link member 4 also moves toward the front of the vehicle toward the rail 11. Start climbing along. In this way, as the two rollers 16 and 17 roll, the link member 4 gradually rises from the initial lying state (the state indicated by the chain line) along the direction of the arrow Y1. Since the rail 11 is inclined upward toward the front of the vehicle, as the roller 16 at the lower end of the link member 4 is pushed by the drive cable 22 toward the front of the vehicle, the drive cable 22, that is, the motor 19 is moved relative to the roller 16. Direction of action of force (that is, direction in which rail 15 extends) and roller 1
The vertical distance between 7 and 7 increases. The moment M about the roller 17 that tries to lift the link member 4 in the direction of the arrow Y1 is represented by the following equation.

Moment M = (urging force F exerted by the motor 19 on the roller 16) × (roller 17 and roller 1
The vertical distance L between the motor 19 and the roller 16 is constant, but the vertical distance L between the roller 17 and the roller 16 increases in the direction of the arrow Y1 of the link member 4. Along with,
growing. That is, the roller 16 is the drive cable 2
The moment M that tries to lift the link member 4 in the direction of the arrow Y1 as it is pushed by 2 and moves forward of the vehicle.
Is increased, and the initial standing motion of the link member 4 is easily performed. After that, when the drive cable 22 continues to push the roller 16 and the roller 16 reaches the position X2 on the most front side of the guide rail 9, the roller 17 reaches the uppermost end of the guide rail 9, and at this time, the motor 1
9 deactivates. During this time, the lift roof 3 is moved to the arrow Y1.
When the roller 16 reaches the position X2, the roof body 2 is fully opened (the state shown by the solid line in FIG. 8). The damper member 6 is in a lying state as shown in FIG. 8 when the roller 16 is in the position X1. Therefore, the urging force of the damper member 6 acts only slightly on the elevating roof 3. As the roller 17 moves up the rail 11, the damper member 6
Also, the sleeping roof gradually shifts to the standing state, and the lifting roof 3
The biasing force exerted on is increased. That is, the damper member 6 begins to exert a biasing force on the elevating roof 3 when the roller 17 reaches a certain point on the rail 11, and promotes the elevating of the elevating roof 3.

That is, the lift roof 3 is initially, that is, while the damper member 6 is not operating so much.
The initial standing motion is performed only by the action of the moment M, and from the time when the initial standing motion is almost finished, the standing action is performed by receiving the biasing force of the damper member 6 in addition to the action of the moment M. In this way, the elevating roof 3 effectively receives the action of the moment M and the damper member 6, and the roof main body 2
Rise against. When closing the elevating roof 3, that is, when lowering the elevating roof 3 toward the roof body 2, the motor 19 is reversed. As a result, the drive cable 22 moves rearward of the vehicle, the roller 16 starts rolling rearward of the vehicle along the rail 15, and the roller 17 descends along the rail 11. These rollers 16,
With the rolling of 17, the link member 4 descends in the direction of the arrow Y2, and when the roller 16 reaches the initial position X1, the elevating roof 3 is closed with respect to the roof body 2 (indicated by the chain line in FIG. 8).
