Is lifted up and down with respect to the roof main body 2 to be fully opened, and then laid on the opening 7. Alternatively, it may be laid on the opening 7 from the beginning. Bed 41 is 3
It is preferable to use one divided or three folds.

Next, referring to FIG. 8, the opening / closing state of the lift 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 such as when the vehicle 1 is running, the roller 16 attached to the lower end of the link member 4 is positioned at the lowermost end of the guide rail 9 (that is, the rearmost side of the vehicle 1). In this state, the link member 4 is in a lying state and the lifting roof 3 is also closed with respect to the roof main body 2 as shown by a chain line in FIG. When the vehicle 1 stops and it becomes necessary to open the lifting roof 3, the motor 19 is rotated forward. The roller 16 starts rolling forward of the vehicle along the rail 15 by the forward rotation of the motor 19, and accordingly, the roller 17 supported at any one point of the link member 4 also moves on the rail 11 toward the front of the vehicle. Start climbing along. As described above, as the two rollers 16 and 17 roll, the link member 4 gradually rises from the initial lying state (the state shown by the chain line) in the direction of the arrow Y1. Since the rail 11 is inclined upward toward the front of the vehicle, the roller 16 at the lower end of the link member 4 is pushed by the drive cable 22 so that the drive cable 22, that is, the motor 19 The direction of action of the applied force (that is, the direction in which the rail 15 extends) and the roller 1
The vertical distance between them increases. The moment M about the roller 17 for raising the link member 4 in the direction of the arrow Y1 is expressed by the following equation.

Moment M = (urging force F exerted on roller 16 by motor 19) × (roller 17 and roller 1
6) The urging force F exerted on the roller 16 by the motor 19 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 connected to the drive cable 2.
2, the moment M which tends to lift the link member 4 in the direction of the arrow Y1 as it moves forward of the vehicle.
Is increased, and the initial rising operation of the link member 4 is easily performed. Thereafter, when the drive cable 22 keeps pushing the roller 16 and the roller 16 reaches the position X2 on the most front side of the guide rail 9 on the vehicle, the roller 17 reaches the uppermost end of the guide rail 9 and at this time the motor 1
9 stops operation. During this time, the lifting roof 3 is moved by the arrow Y1.
When the roller 16 reaches the position X2, the roof body 2 is fully opened (a state shown by a solid line in FIG. 8). When the roller 16 is in the position X1, the damper member 6 is in a lying state as shown in FIG. For this reason, the urging force of the damper member 6 acts only slightly on the lift roof 3. As the roller 17 moves up the rail 11, the damper member 6
Also gradually shifts from the sleeping state to the standing state,
The biasing force exerted on is increased. That is, the damper member 6 starts exerting an urging force on the lift roof 3 when the roller 17 reaches a certain point on the rail 11, and promotes the lift of the lift roof 3.

That is, the lifting roof 3 initially moves, that is, while the damper member 6 does not operate much.
The initial rising operation is performed only by the action of the moment M, and the rising operation is performed by receiving the urging force of the damper member 6 in addition to the action of the moment M from the time when the initial rising operation is almost completed. As described above, the lift roof 3 is effectively subjected to the action of the moment M and the damper member 6, and
Rise against. When closing the lifting roof 3, that is, when lowering the lifting roof 3 toward the roof main body 2, the motor 19 is reversed. As a result, the drive cable 22 moves to the rear of the vehicle, the roller 16 starts rolling backward of the vehicle along the rail 15, and the roller 17 descends along the rail 11. These rollers 16,
As the roller 17 rotates, the link member 4 descends in the direction of arrow Y2, and when the roller 16 reaches the initial position X1, the lifting roof 3 is closed with respect to the roof main body 2 (see the chain line in FIG. 8).
