As shown in FIGS. 2a and 2b, it is provided with a rectangular insertion hole 17a, and is formed into a crank shape when viewed from the side, and a lock pin 19 is fixedly installed in the bent portion 17b. Further, a handle portion 17c is bent and formed at the tip of the positioning plate 17. Further, one end of the leaf spring 11 is bent upward to form an engaging portion 11a, and the width of the engaging portion 11a is approximately the same as the width of the insertion hole 17a of the positioning plate 17. has been done. Therefore, the side cover 15 is attached to the fuselage 2.
When the side cover 15 is rotated toward the side cover 15, the lock pin 19 engages with the engagement portion 11a of the leaf spring 11 while the insertion hole 17a of the positioning plate 17 sandwiches the engagement portion 11a of the leaf spring 11 from both sides.
are positioned and fixed so that they do not come off in the front, rear, and lateral directions of the aircraft. Furthermore, since the leaf spring 11 is installed so as to be located inside the bonnet 6 when viewed from the side, the side cover 15
When the bonnet 6 is turned toward the fuselage 5 and closed, the portion where the positioning plate 17 and the leaf spring 11 are engaged is covered by the side of the bonnet 6. has been done. Thereby, the side cover 15 is configured so that it can be opened only when the bonnet 6 is open.

Since this embodiment has the above configuration,
In the closed state of the side cover 15, the pin 13 is fitted into the fitting hole 16a of the plate member 16, and the engaging portion 11a of the leaf spring 11 is fitted into the fitting hole 17a of the positioning plate 17, and the lock pin 19 is fitted into the fitting hole 16a of the plate member 16. It is fixed to the body 2, that is, the bracket 10, by engaging with the engaging portion 11a. Then, the bonnet 6 is fixed with the locking device 9,
Further, the engaging portion between the leaf spring 11 and the positioning plate 17 is covered by the side portion of the bonnet 6.

When repairing, inspecting, or replacing the engine 3, radiator 5, battery, etc.,
The operator first releases the lock device 9 and rotates the bonnet 6 about the hinge 7 in the forward direction of the machine. Then, the handle 1 of the positioning plate 17 that was covered by the side of the bonnet 6
7c is exposed. When the handle portion 17c is put on the handle portion 17c and pulled in the lateral direction of the body 2, the lock pin 19 fixed to the positioning plate 17 locks the leaf spring 1.
It comes off while bending the engaging portion 11a of No. 1 downward.
As a result, the side cover 15, which is released from restrictions in the front, rear, and lateral directions of the fuselage, is rotated in the lateral direction of the fuselage around the hinge member 14 in that state. After the rotation, when the side cover 15 is slid toward the rear of the aircraft,
The insertion hole 16a of the plate member 16 is removed from the pin 13, and the side cover 15 is completely removed from the body 2. Then, work such as repair and inspection is performed with the bonnet 6 and side covers 15 removed.

On the other hand, when returning the bonnet 6 and side cover 15 to the closed state after completing this work, first, move the side cover 15 by sliding it from the rear of the fuselage 2 while keeping the bonnet 6 in the open position. Then, the insertion hole 1 of the plate member 16
6a is fitted onto the pin 13. Then, the side cover 15 is rotated toward the body 2 while pressing the side cover 15 around the plate member 16 and pin 13 . Then, the engagement portion 11a of the leaf spring 11 is bent by the lock pin 19 while entering the insertion hole 17a of the positioning plate 17, and the pin 19 and the engagement portion 1
1a are engaged. In this state, the positioning plate 17 has the engaging portion 11a in its insertion hole 17a.
Because it is fitted into the fuselage, forward and backward movement of the aircraft is restricted. Therefore, the side cover 15 is positioned and fixed in the front, rear, and lateral directions of the body 2. Thereafter, when the bonnet 6 is rotated about the hinge 7 toward its closed position, the side portion of the bonnet 6 covers the portion where the engaging portion 11a of the leaf spring 11 and the lock pin 19 are engaged. For,
The side cover 15 is protected from being accidentally opened while driving.

(G) Effect of the invention As explained above, according to the invention, one member 16a of the hinge member 14 is attached to the side cover 15.
and a positioning member 17, and a bracket 1
0, the other member 13 of the hinge member 14 and the leaf spring 11 are installed, and both members 1 of the hinge member 14 are
3 and 16a, and furthermore, the lock portion 19 provided on the positioning member 17 is engaged with the engaging portion 11a of the leaf spring 11, and the engaging portion 11a is inserted into the fitting hole 17a.
Since the side cover 15 is configured to be fitted in, although it has a simple structure, it is possible to reliably position and fix the side cover 15 in the front, rear, and lateral directions of the fuselage when it is in the closed state.
When opening, the side cover 15 can be easily opened by simply pulling the positioning member 17 in the lateral direction of the machine body, thereby providing a highly operable side cover 15 that can be opened and closed with a single touch. Also,
The positioning of the side cover 15 in the longitudinal direction of the aircraft is as follows:
Since the side cover 15 is released when the leaf spring 11 is removed from the insertion hole 17a, the side cover 15 can be removed as soon as the leaf spring 11 is no longer held in the closed position, and there is no open space for the side cover in a small room. The side cover can be easily removed. Furthermore, since the side cover 15 can be easily removed when it is opened, the side cover 15 does not get in the way when repairing or inspecting the inside of the bonnet 6, and work efficiency can be improved. Further, the leaf spring 11 having the engaging portion 11a engages with the locking portion 19 to hold the side cover 6 in the closed position.
In addition, since it is also used for positioning the machine body in the longitudinal direction by fitting into the insertion hole 17a of the positioning member 17, the number of parts can be reduced, and the side cover 15
It is possible to reduce the space for the fixed portion of the device, reduce the occurrence of failures, and reduce costs.

Furthermore, when the bonnet 6 is in its closed position,
Since it is configured to cover the engaged portion of the lock portion 19 and the engaging portion 11a, the side cover 15 cannot be easily opened when the bonnet 6 is closed, so the side cover 15 may be opened while driving or the like. It is possible to reliably prevent this from occurring and improve safety.

Furthermore, a handle portion 17c is provided at one end of the positioning member 17.
By providing this, the side cover 15 can be opened and closed even more easily by placing the hand on the handle portion 17c.
