Abstract
A fluid discharge apparatus includes a storage chamber, a moving body, a drive mechanism, and a coupling member. The storage chamber includes a discharge port to discharge the fluid. The moving body includes a leading end portion facing the discharge port inside the storage chamber. The drive mechanism is positioned on the opposite side of the moving body to the discharge port, and performs an operation to reciprocate the moving body. The coupling member couples the moving body to the drive mechanism such that the moving body is attachable and detachable. The coupling member includes a biasing section to apply an elastic force in a direction to move the moving body toward the drive mechanism, and, while pressing the moving body against the coupling member, to support the moving body in a state in which the moving body is capable of elastic displacement in a direction toward the discharge port.
