PROBLEM TO BE SOLVED: To provide a liquid pump which has high reliability.SOLUTION: A liquid pump 1a is equipped with a container (10); a shaft (30); a bearing (40); a pump mechanism (20); a collection space (50); and a liquid supply path (60). The shaft (30) is disposed in the inside of the container (10). The bearing (40) supports the shaft (30). The pump mechanism (20) press-feeds liquid by rotations of the shaft (30). The collection space (50) is formed so as to collect liquid to be sucked into the pump mechanism (20) or liquid let out from the pump mechanism (20) to be discharged to the outside of the container (10), on the outside of the pump mechanism (20) of an inner space of the container (10). The liquid supply path (60) is a channel which has an inlet facing the collection space (50), and supplies the liquid collected in the collection space (50) to the bearing (40).SELECTED DRAWING: Figure 1 |
