PROBLEM TO BE SOLVED: To provide an underwater motor scooter allowing selectively obtaining of two mutually conflicting advantages of reduction of the burden to an operator accompanied by an increase in size and improvement of maneuverability accompanied by miniaturization. SOLUTION: An air tank 22 to be a riding part is arranged in a main frame 12 for a riding type and the operator (OP) can be ridden on this underwater motor scooter 10, to reduce the burden. This scooter 10 is provided with a main frame for a traction type formed to be shorter than the main frame 12 for the riding type. By replacing the main frames, the underwater 10 is changed from the riding type to the traction type. As a result, the scooter 10 is miniaturized (the whole length is shortened) to improve maneuverability. COPYRIGHT: (C)2006,JPO&NCIPI
