(Problems to be Solved by the Invention) However, in the conventional structure as described above, when a load is applied to the hatch roof from the inside to the outside, elastic deformation of the glass causes the center hook and the glass wrap margin. There was a risk that it would come off and come off.

For this reason, if the lap size is increased to prevent this disengagement, the center hook becomes larger, the glass area of the hatch roof becomes smaller, and the open feeling is diminished, and the weight and cost increase. Occurs.

In view of the above problems, the present invention aims to improve the detachment strength of the hatch roof without enlarging the center hook.

(Means for Solving the Problems) In order to achieve the above-mentioned object, in the center hook structure for a T-bar roof for an automobile of the present invention, a pair of left and right openings are formed in the roof by the roof center provided in the center of the roof. In order to open and close the opening, a hatch roof is detachably attached to the roof, and the roof center is
A center hook for fixing the hatch roof is attached to the center hook, and a lap portion is formed on the center hook of the hatch roof. A stopper portion having a step portion projecting above the general portion of the hatch roof is formed at the side edge portion, and the stopper portion is provided so as to project downward on the lap portion and is attached to the hatch roof. And a locking portion that is locked by abutting in the vehicle width direction.

(Operation) In the center hook structure of the T-bar roof for an automobile of the present invention, when the hatch roof is mounted, the hatch center roof edge portion is inserted into the lower surface side of the lap portion of the center hook so as to be overlapped. The edge of the roof on the center side of the roof is prevented from coming off, and the stopper portion of the hatch roof and the engaging portion of the center hook are mounted so as to be engageable in the vehicle width direction. The lockable state means that the locking part and the stopper part are already locked when the hatch roof is mounted, and that the hatch roof is moved in the vehicle width direction from the position at the time of mounting. This includes the case where the locking portion and the stopper portion are in the locked state.

Therefore, the edge portion of the hatch roof on the center side of the roof can be locked upward with respect to the lap portion of the center hook and can also be locked with respect to the locking portion in the vehicle width direction.
