Document Type and Number:
Japanese Patent JP6967780
Kind Code:
B2
Abstract:
To provide a diaphragm pump which can maintain improvement of detection sensitivity.SOLUTION: In a diaphragm pump 1, a guide member 43 is provided at a detection device 4 to cause a compression spring 42 to expand or contract along an X direction that is a moving direction of a sensor 41 and inhibit the compression spring 42 from expanding and contracting obliquely relative to the X direction. The structure makes the compression spring 42 and the sensor 41 less likely to contact with each other and can inhibit breaking of the compression spring 42. Thus, the structure can maintain improvement of detection sensitivity achieved by providing a biasing means and the compression spring 42.SELECTED DRAWING: Figure 3
