It is blindfolded by S so that it cannot be seen from the inside.

In the hood type sunroof device configured in this way,
The front movable body 25 in the fully closed state is moved by the geared cable 21 that meshes via the drive slider 45, and the rear movable body 29.
The hook arms 77 ensure the restrained state. In this state, if the drive motor 19 index-controls the guard cable 21, the front movable body 25 is moved rearward by the front elevating mechanism 31 with its rear end side inclined upward as shown in FIG. By this movement, the slider section 41
In order to press the pressing portion 56 of the fixing slider 51 whose rear end is located first, the floating slider 53 is pressed via the hinge arm 63, and the engaging hook portion 61 is disengaged from the engaging member 59. To rise. Below, the first fixing slider 51
The pressing portion 56 presses the pressing portion 56 of the fixing slider 51 that follows the pressing portion 56. As a result, the engaging hook portion 61 of the slider 53 for floating, which is located at the end, disengages from the engaging member 59 and rises. Then, when the backward movement of the front movable body 25 is completed, the raised support body 27 allows the hood 23 to be in a fully open mode in which it is folded into two tiers. Next, if the front movable body 25 in the fully open position is moved forward, the slider portion 41
The slider hook portion 41a comes into contact with the stopper 40 and is prevented from moving forward. At the same time, the first arm 35 rotates counterclockwise and the second arm 37 rotates clockwise, the front movable body 25 descends, and when it is fully closed, it makes strong elastic contact with the outer and inner seal members 16a, 16b. A proper sealing condition will be secured. On the other hand, the rolling roller 43 is engaged in the engaging recessed portion 17 and the upward floating is restricted. As a result, the hood 23 does not float during high-speed traveling, and a stable sealed state can be obtained. In order to open the rear side, the operation handle 73 is operated to the operating position opening, and the hook portion 81 is disengaged from the striker 83, so that the engagement is released. Therefore, if the rear movable body 29 is moved forward, the roof opening is performed. A mode in which the rear of 9 is opened is obtained.

[Effect of the Invention] As described above, according to the hood type sunroof device of the present invention, the fully-closed state is completed by the first arm that comes into contact with the stopper when fully closed and the drive slider that drives the second arm. Since the hood at this time is in a state of strongly elastically contacting the roof opening side, a reliable seal is secured and the structure is simple.
