<p>PROBLEM TO BE SOLVED: To provide a suction nozzle which allows for enhancement of decomposition and assembly workability, while reducing the number of components.SOLUTION: A suction nozzle 5 includes a shaft-like nozzle body 50 integrally including an axial engaging portion 54 protruding outward, a cylindrical holder portion 60 into which the nozzle body 50 is inserted in the axial direction and held in place, and a spring member 70 for energizing the nozzle body 50 to the tip side in the axial direction for the holder portion 60. The holder portion 60 integrally includes an inside upper surface 65a protruding to the inside of the holder portion 60, and not engaging when the direction of the axial engaging portion 54 of the nozzle body 50 is a first rotation angle about the axis, but engages in the axial direction when it is a second rotation angle different from the first rotation angle.</p> |
