Japanese Patent No. 29679 discloses that it is difficult to provide a balance weight mounting portion on the front surface or side surface of the fuselage or on both side surfaces of the fuselage closely, because it interferes with the steering and steering members of the front wheels. In addition, a separate member was required to lock the individual balance weights. In addition,
As is known from Japanese Patent No. 10248, a concave portion is provided on the upper surface of a basic weight integrally attached to a traveling body, and a flat auxiliary weight is fitted and mounted in the concave portion in a horizontal state. The method requires a fastening member for fixing the auxiliary weight after fitting and mounting the auxiliary weight in a horizontal state in the concave portion, and has an inconvenient surface in handling. Furthermore, as known in Japanese Patent Application Laid-Open No. 103116/1990, a pair of left and right support portions is fixed to the body fixing portion so as to be located in front of the front wheel, and a balance weight that can be attached to and detached from the left and right support portions is also provided. The inconvenience in handling that the balance weight is attached to the vertical surfaces of the left and right support portions while holding the balance weight with one hand and attaching with the other hand using a fastening member remains.
