In the connecting hood of this type, the functional member that causes the movable side hood structure to extend forward is as follows:
Conventionally, as disclosed in Japanese Patent Publication No. 64-36561, an organic elastic material such as rubber, sponge or urethane foam has been used, and this constitutes the main body of the canopy. In addition, as a method for preventing the movable side hood structure from drooping without using such an organic elastic material, the movable side hood structure is generally attached to a hood suspension rod or hood suspension spring installed between the gable surfaces of the vehicle body. It is held suspended.

A-3 Problems to be Solved by the Present Invention If the main body of the hood is made of an organic elastic material as in the prior art, it will emit smoke or burn itself in the event of a fire, and considerable research is needed to solve this problem. There are problems that require effort. Furthermore, in the case of the above-mentioned hood suspension rods and hood suspension springs, they are generally installed so as to be exposed to the outside of the hood, and as a result, the appearance is not necessarily sleek. In recent years, there has been a trend for vehicles to have a sleek overall appearance, so the appearance of the top is also required to be smart, and the use of the above-mentioned top suspension rods and the like has become a problem.

Therefore, the present invention is designed to reduce the use of organic materials as much as possible, and also to make it possible to perform the mutual pressing type hood function without using the hood hanging rods exposed to the outside of the hood. The purpose is to solve the above-mentioned problems.

B. Structure of the Invention B-1 Means for Solving the Problems In order to solve the above-mentioned problems, the present invention divides the middle part of the hood, and the divided hood structures 3 and 4
In the case where the
A fixed hood metal frame 6 consisting of inner and outer walls 6a, 6b surrounding the entire periphery of the left and right sides and upper and lower parts of the passageway 7, which crosses both hood structures 3 and 4, and an inner frame 6 that similarly surrounds the entire periphery of the passageway 7. It is divided into a movable hood metal frame 9 consisting of outer walls 9b, 9c and a front wall 9a, and the fixed hood metal frame 6 is fixed to the gable side of the vehicle body, and the movable hood metal frame 9 is attached to the fixed hood metal frame 6.
The inner wall 6 of the two hood metal frames 6 and 9 is arranged in front of the
Of the movable hood frame 9, the inner wall 9b located on the crossover passage side overlaps the other inner wall 6a at a predetermined distance from the inner wall on the passage side, and the inner wall 9b of the movable hood frame 9 is fixed. A sliding member is located on one of the inner walls 6a of 6 and holds the movable hood metal frame 9 so that it can move in the axial direction of the passage 7, and also prevents lateral displacement from left and right and regulates vertical movement. 10 are provided at the top, bottom, right and left of the passageway 7, and the outer wall 9c of the movable canopy frame 9 and the fixed canopy frame 6 are provided.
An outer coating 11 is installed between the outer walls 6b to cover the upper, lower, left and right outer surfaces thereof, and the front wall 9 of the movable canopy frame 9 is
A metal pressing member 12 is installed between the inner walls 6a, 9b and the outer walls 6b, 9c and presses the front wall 9a of the movable hood metal frame 9 forward. It is characterized by this.
