Abstract
A working machine includes a traveling vehicle that is a first moving entity, a working device that is a second moving entity coupled to the first moving entity, and a sub battery loaded on the second moving entity to store an energy source to drive the traveling vehicle. Therefore, it is not necessary to newly provide a configuration to load the sub battery on the traveling vehicle, and a battery can be easily loaded. In a case where the traveling vehicle includes a main battery, the traveling and work can be continued according to a capacity of the sub battery without being stopped in order to charge the main battery that has a decreased remaining charge level.
