Abstract
A manual breast pump which can be handled conveniently and disassembled with ease for cleaning or other purposes although it would not be disassembled by error in operation. The manual breast pump can include a conical suction portion, which is made to abut a breast and includes a breast pump main body that is held in communication with a bottle, and a lever with long shape in a direction and detachably fitted to the breast pump main body at a middle position thereof by means of a rotative and supportive shaft. The lever is adapted to turn in opposite directions around the shaft. The lever is operated so as to relatively reciprocate a piston and generate negative pressure so that the suction portion that is held in communication with an internal space of the lever sucks milk and causes the sucked milk to fall into the bottle.
