Abstract
An electromagnetic vibrating diaphragm pump is provided which is safe even when a diaphragm of a diaphragm pump is damaged and liquid or flammable gas penetrates an electromagnetic drive. An electromagnet coil container containing electromagnet coils in an airtight manner is further provided inside a casing, preventing fluid which has penetrated into the space outside the electromagnet coil container from penetrating into the space inside the electromagnet coil container. The electromagnet coil container has a passage formed for an oscillator to move in reciprocation and the passage is formed of a partition wall outside the container. The electromagnetic coil container is configured to prevent fluid which has penetrated into the space inside the passage from penetrating into the space inside the electromagnet coil container.
