Abstract: A controller of a thrust generating device executes one of first control of controlling thrust by changing the pitch angle of each blade while maintaining the rotational speed of a propeller at a reference value, or second control of allowing the thrust greater than the thrust generated in the first control to be generated by making the rotational speed of the propeller larger than the reference value.

Abstract: A battery pack includes a casing, a plurality of battery cells, and a first connector, for example. The casing includes a first outer wall and a protrusion that is provided on the first outer wall and protrudes outward from the first outer wall. The battery cells include an electrode terminal and are housed in the casing. The first connector is provided on the protrusion and is electrically connected to the electrode terminal.

Abstract: A battery pack includes a first casing, a plurality of battery cells, and a second screw, for example. The first casing is supported by a support member and includes an insulating first outer wall. The battery cells are housed in the first casing. The first outer wall is provided with a second screw that is connectable to a first screw. The first casing is supported by the support member with the first screw fitted into the second screw, placing the support member in-between the first screw and the second screw.

Abstract: A battery pack includes a plurality of battery cells. The battery cells are aligned in a first direction, and each include a positive electrode terminal having one of a male structure and a female structure of a shape to be fitted to the male structure by press-fitting, and a negative electrode terminal having the other of the male structure and the female structure.

Abstract: A battery pack includes a plurality of battery cells, a pipe, a bar, and an insulating plate, for example. The battery cells are aligned in a first direction and each include an opening. The pipe is hollow and inserted into each opening in the first direction. The bar is inserted into a hollow of the pipe. The insulating plate is provided between opposing faces of the battery cells.
