DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) This invention relates to a hood structure of a hood type sunroof device in which a hood that can be opened and closed is provided in a roof opening of a vehicle body, and particularly supports the hood. The present invention relates to a hood structure of a hood type sunroof device having a hood bone extending in the vehicle width direction.

(Prior Art) There is a hood type sunroof device called a canvas top in which a hood is provided in a roof opening of a vehicle body, and the hood is folded and moved in the vehicle front-rear direction to open and close the roof opening. This sunroof device has a large roof opening area compared to a rigid lid that slides or tilts up, giving you a feeling of openness of the interior space that tends to be sealed, and it is mainly used for small displacement vehicles. ing.

As a hood structure of such a sunroof device, for example, there is one as shown in FIG. 6 (see Japanese Utility Model Laid-Open No. 63-39026). In the outer cover 1 of the hood in the hood structure described in this publication, both side edges in the vehicle width direction are supported by a plurality of hood bones 3 extending in the vehicle width direction. The outer cover 1 is provided with a folded-back portion 5 in which both side edges in the vehicle width direction are folded back toward the inside of the vehicle. It is joined.

On the other hand, the hood bone 3 is inserted into the insertion holes 9 and 11 formed in the folded-back portion 5 inside the joint portion 7, and the tip end side is further bent so as to be wound around the belt member 13 attached to the folded-back portion 5. It is fixed to tension 1. An inner lining (not shown) exposed inside the vehicle with respect to the outer tie 1 exposed outside the roof is attached to the hood bone 3 so as to cover the hood bone 3.

(Problems to be solved by the invention) However, in such a hood structure, due to the opening / closing operation of the hood, or the influence of traveling wind particularly in the half-opened state, the hood bone is in the vehicle longitudinal direction with respect to the insertion hole of the folded portion Force, and tear the folded part to enlarge the insertion hole,
As a result, the top bone is displaced with respect to the outer lining, and there is a problem in that when the hood is fully closed, wrinkles are generated on the inner lining and the appearance of the ceiling is impaired.

Therefore, for example, as shown in FIG. 7 of Japanese Utility Model Laid-Open No. 61-78020, a hood bone inserted from an insertion hole 21 into an insertion portion 19 between the hood outer covering 15 and its folded portion 17. 23 tips
It is conceivable that a reinforcing member 25 extending in the longitudinal direction of the vehicle body is attached to 23a, or a fixing member for the hood bone is attached as a separate member to the folded-back portions on both sides of the exposed portion of the hood bone.

However, in this case, since a dedicated member for fixing the top rib is required, the assembling work becomes complicated, and at the same time, the number of parts increases and the weight increases.

Then, this invention aims at preventing the displacement of the hood on the tip side of the hood with respect to the external tension, without providing a member for fixing the hood.

[Means for Solving the Problems] (Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides an openable and closable hood consisting of an outer lining and an inner lining in a roof opening of a vehicle body. In a hood structure of a hood-type sunroof device in which the outer lining and the inner lining are independently supported by a plurality of hood bones extending in the width direction and provided between the outer lining and the inner lining,
The folded-back portion folded back to the vehicle width direction side edge portion of the outer covering is joined to the back side of the front-rear outer covering along the vehicle body front-rear direction,
A bag-shaped insertion part, into which the tip of the top bone is inserted, is formed between the front end part and the rear end part of the joint region, and the front end part of the joint region in the front-rear direction forming the insert part is joined. The joint region is extended continuously or intermittently with the rear end portion along the insertion direction to provide a wall along the insertion direction.

(Operation) When relative movement in the vehicle front-rear direction occurs between the tip of the hood and the outer covering due to the opening / closing operation of the hood or the influence of traveling wind in the half-opened state, the outer covering of the hood will be applied. The wall of the joining region between the outer tension and the folded portion formed along the insertion direction of the above prevents this movement and prevents the wrinkling of the inner tension when the hood is fully closed.
