To provide a liquid soap feeder that prevents a nozzle body from slightly moving to a tip side with respect to a nozzle body insertion hole when the nozzle body is fixed to the nozzle body insertion hole of a body.SOLUTION: A liquid soap feeder includes a body having a nozzle body insertion hole, and a nozzle body inserted into the nozzle body insertion hole of the body. The nozzle body is provided with a through hole penetrating the nozzle body in an oblique direction. An end part at one side of the through hole is positioned outside the nozzle body insertion hole and exposed with the nozzle body beng inserted in the nozzle body insertion hole, and an end part at the other side of the through hole is positioned inside the nozzle body insertion hole with the nozzle body being inserted in the nozzle body insertion hole. The nozzle body insertion hole is further provided with a female screw hole extending in the same direction as the through hole at a position aligned with the end part at the other side of the through hole. A slip-off preventing screw is inserted from the end part at one side of the through hole, passes through the through hole, and is screwed into the female screw hole.SELECTED DRAWING: Figure 2
