摘要

A joint (40) according to an embodiment of the present invention is a device which is positioned between an air supply unit and a nozzle that washes an article to be washed using air that is supplied from the air supply unit and which is for confirming a delivery position for air sprayed from a hole in the nozzle, said joint (40) being provided with: a tube-shaped connection member (41) which is provided with an air inlet part (41b) and an outlet part (41a); and a holder (43) that has an opening (43a) for disposing a light source unit and has a light source unit disposition space (43c) for holding the light source unit such that the light emitted by the light source unit is radiated toward the outlet part (41a). Thus, confirmation of the delivery position of a fluid that is blown out is facilitated, and general versatility can be increased.
