Abstract

PURPOSE:To heighten a speed even if a device is operated with a prime mover of the same output as a thrust can be increased by containing a propeller in an internal cylinder in a vessel body. CONSTITUTION:At the rear lower section of a vessel body 1, an intake 5 is set, and an internal cylinder 8 containing a propeller 4 is set and is connected to the intake 5, and the jet port 6 of the internal cylinder 8 is opened. The propeller 4 for rotating with a driving shaft 3 can obtain a thrust F3 by directing water current backward with the internal cylinder 8 through the force F2 of water running away in the diameter direction besides a thrust F1. As this result, the thrust of the propeller contained in the cylinder is made greater than the thrust of a bare propeller.
