It is expected that 3 will be deformed and detached.

[Problems to be Solved by the Invention] Therefore, in this invention, as shown in FIG. A hole 31c is provided in the base 31a of the hook provided on the front edge of the hook, and the second tongue piece 74 is inserted into the hole 31c to hold the engine cover 2 in the upright open state. Even if it is greatly flexible and curved, the second tongue piece 74 will not fit through the perforation 3 of the hook base 31a.
The challenge is not to leave 1c.

[Means for Solving the Problems] In this invention, the hook connects a plate-shaped base to the front edge of the engine cover, and connects a U-shaped hook formed at one end of the base to the front edge of the engine cover. The hook protrudes at a predetermined position from the edge, and the front end of the hook base is provided with a perforation capable of locking the tip of the holder. a flexibly deformable main body formed in a shape, an annular body provided at the other end of the main body, and an annular body facing from one frame side of the annular body to the other so as to partially close the space within the frame of the annular body. a deformable first tongue piece formed toward the frame side of the annular body, and a first tongue piece protruding from the other frame side of the annular body toward the opposite frame side of the annular body so as to be inserted into the perforation of the hook base. A gap is formed between the tips of the first and second tongues through which the base of the hook can be inserted.

When opening the floor opening, which is closed by the engine cover, for engine service, etc., first release the latch, and then lift the engine cover together with the seat. and rotate it backwards around the hinge,
The engine cover is placed in an upright position, and at the same time, the main body of the holder stored on the back side of the backrest is moved beyond the upper surface of the backrest so that the annular body of the holder faces above the hook of the engine cover. ,
Grasp the plate part of the holder, insert the hook part of the hook, insert the second tongue piece into the hole at the base of the hook, and release your grip.The engine cover will be inserted by its own weight, and the first tongue piece will be inserted at the same time. The tongue piece is flexibly deformed by the hook part of the hook, and the hook part of the hook penetrates the space between the tips of the first and second tongue pieces formed within the frame of the annular body and is fitted into the space within the frame. By restoring the first tongue piece to its normal free state, the engine cover is held in the open state.

By the way, while engine service is performed with the engine cover held open, a body, tools, etc. may come into contact with the engine cover or the seat, causing the engine cover to rotate and the main body of the holder to become flexible. Even if the holder of this invention is greatly curved, the second tongue piece remains inserted into the hole in the hook base and can restrict the detachment of the hook portion of the hook, so that the open state of the engine cover is reliably maintained.

In addition, in the holder of this invention, when a body, a tool, etc. comes into contact with the engine cover or the seat while the engine cover is held in an upright state, an impact force is applied to the holder main body, and the second tongue piece is removed. Even if the hook were to come off the hole in the hook base, the first tongue piece would fit into the approximately U-shaped groove of the hook hook and prevent it from coming off from the annular body. ,
With the help of the engine cover's own weight, the second
The tongue piece is inserted into the hole in the hook base again, so that the engine cover is supported by the annular body of the retainer and is reliably kept in the open state.
