By adopting a combined structure of the upward groove 131a and the downward groove 132a, it is not necessary to form a through hole in the other portion 84b of the hinge portion 84.
Therefore, it is possible to simplify the equipment of the mold for forming the battery fixing member 81 and reduce the equipment cost.

FIGS. 9A and 9B are views for explaining the operation of the hinge portion of the small snowplow according to the present invention.
In (a), the battery 51 is accommodated from above in the battery holder 77 of the battery support structure 70 for an aircraft, and the battery 51 is placed on the battery mounting tray 76.
Next, the battery fixing member 81 is rotated as indicated by an arrow a with the hinge rod 85 as an axis.

In (b), the upper part 108 b of the hook bolt 108 is inserted into the attachment hole 121 of the left end 83 of the battery fixing member 81 constituting the fuselage battery support structure 70, and the upper part 108 b of the hook bolt 108 protrudes from the attachment hole 121.
The wing nut 109 is set to the upper part 108b protruding from the mounting hole 121 as shown by the arrow b, and the set wing nut 109 is screwed to the upper part 108b.
Thereby, the upper surface 51 a of the battery 51 is pressed by the battery fixing member 81, and the battery 51 is held in the battery holder 77.

Returning to FIG. 7, by using the battery fixing member 81 of the battery support structure 70 for an airframe as an insulating resin part, even if the battery fixing member 81 contacts the terminal 55 of the battery 51, there is no short circuit. Therefore, the attachment position of the battery fixing member 81 is not limited by the battery terminal 134.
Furthermore, since the battery fixing member 81 is an insulating resin component, it is not necessary to form a resin film on the surface of the battery fixing member 81.

Here, a terminal (not shown) of an electric wire 129 (see FIG. 6) is normally connected to the terminal 55 of the battery 51, and the terminal 55 is covered with an insulating cover member 135.
However, the cover member 135 is for protecting the terminal from dust and the like, and it is not preferable that the conductive member abuts on the terminal 55.
Therefore, when a conductive component is used for the battery fixing member, the battery fixing member needs to be attached avoiding the terminal 55, and the attachment position of the battery fixing member is limited by the terminal 55.
In view of this, the battery fixing member 81 is used as an insulating resin part to eliminate the above-described problem.

  Further, the battery fixing member 81 includes a flexible portion 137 that can be elastically deformed in the central portion (central portion of the battery fixing member) 117a in the width direction (left-right direction) of the base 117 or in the vicinity of the central portion 117a. The bent portion 137 is formed by forming a concave portion 117b at the center of the bottom portion of the base 117, thereby reducing the thickness of the base 117.

By simply forming the recess 117b at the center of the bottom of the base 117, it is possible to easily form the flexure 137 that can be elastically deformed.
By elastically deforming the bent portion 137, the left and right contact surfaces 83a and 82a provided on the left and right end portions (both end portions) 83 and 82 of the battery fixing member 81 are surely brought into contact with the upper surface 51a of the battery 51. The left and right contact surfaces 83 a and 82 a are surfaces constituting the bottom surface of the base 117.
By bringing the left and right contact surfaces 83 a and 82 a into contact with the upper surface 51 a of the battery 51, the battery 51 is pressed and held by the left and right contact surfaces 82 a and 83 a of the battery fixing member 81.

Further, the right end (one end) 82 of the battery fixing member 81 is hinged to the battery holder 77, and the left end (other end) 83 is detachably connectable to the battery holder 77.
Therefore, the battery 51 can be removed from the battery holder 77 simply by releasing the connection between the left end 83 of the battery fixing member 81 and the battery holder 77.
Further, the right end 82 of the battery fixing member 81 is hinged to the battery holder 77, so that the battery 51 can be removed from the battery holder 77 in a state where the right end 82 of the battery fixing member 81 is connected to the battery holder 77. It becomes possible.

Further, a contact surface 83 a that contacts the upper surface 51 a of the battery 51 when the left end portion 83 of the battery fixing member 81 is coupled to the battery holder 77 is provided at the left end portion 83.
Therefore, the contact surface 83a of the left end portion 83 can be brought into contact with the upper surface 51a of the battery 51 without bending the elastically deformable bending portion 137 more than necessary.

Further, when the right end portion 82 of the battery fixing member 81 is coupled to the battery holder 77, the left end portion 83 is provided with a taper portion 138 that contacts the upper corner portion 51b of the battery 51.
Therefore, by pressing the upper corner portion 51b of the battery 51 with the taper portion 138, the battery 51 is moved to the right end portion 82 side of the battery fixing member 81, and the battery 51 is positioned at a normal position.
