Abstract
An underwater propulsion unit including a propeller, a motor, and a housing. The motor is disposed further forward in a propulsion direction than the propeller and drives the propeller into rotation. The housing that accommodates the motor and the propeller includes a first portion and a second portion. In the second portion disposed further rearward in the propulsion direction than the first portion, an introduction inlet and a spout outlet are provided. The introduction inlet introduces water into the housing, and water introduced from the introduction inlet and delivered by the propeller is spouted out of the housing. When viewed in a direction parallel to the propulsion direction, the introduction inlet is disposed further outward than the first portion and introduces water into the housing in a direction parallel to the axis of the propeller.
