<p>PURPOSE:To make a suction nozzle adjustable at an optional angle for a cylindrical main body, by providing a spherical cylinder on the base end of the suction nozzle, housing the spherical cylinder rotatably into a cap, and holding the spherical cylinder fixedly by the fastening of the cap. CONSTITUTION:A spherical cylinder 20 is supported by a sliding face 19b and tapered face 18b at its outer peripheral face, its rotation becomes possible in the state of the screwing of a cap 19 with a connection end part 18 being loosened and it is held so as not to be rotated in the state of the cap 19 being strongly fastened. The angle of a suction nozzle 17 is optionally set, therefore, so that the suction face 16a of a suction panel 16 becomes most suitable for sucking the body to be sucked and the state thereof can be held. By the way, a locking face 19c acts as the stopper on which the suction nozzle 17 abuts in the case of the suction nozzle 17 being made at the maximum inclination angle and a recessed spherical part 20a is for making the air circulation into the communicating hole 12 of a cylindrical body 11 not becoming worse even in the case of the suction nozzle 17 being inclined.</p> |
