The long hole 29 penetrates from the outer periphery of the nozzle body holding portion 22 to the fitting hole 25 . A cylindrical pin 30 protrudes in the radial direction of the fitting hole 25 (horizontal direction orthogonal to the vertical direction) from the base end portion 26 of the nozzle body 21 inserted into the fitting hole 25 of the nozzle body holding portion 22 . is installed.

In FIG. 6, left and right ends 30a and 30b of a pin 30 protruding from the nozzle body 21 protrude into long holes 29 formed in the nozzle body holding portion 22, respectively. That is, the pin 30 is attached to the nozzle body 21 through the opposed long holes 29 . As the nozzle body 21 slides up and down, the pin 30 moves up and down inside the long hole 29 (arrow a in FIG. 8B). The nozzle body 21 that moves up and down is restricted from rotating about the vertical direction as the axis of rotation by the pin 30 and the long hole 29 .

In this manner, the pin 30 is provided in the base end portion 26 so as to protrude in the radial direction of the fitting hole 25, and the side surface 22b of the nozzle body holding portion 22 has a fitting hole along the direction in which the nozzle body 21 slides.

In FIG. 5, the length L1 above the elongated hole 29 including the elongated hole 29 of the base end 26 is longer than the length L2 of the elongated hole 29 in the direction in which the nozzle body 21 slides (vertical direction). Therefore, even when the nozzle body 21 is moved to the lower restriction position, the long hole 29 is closed by the outer peripheral surface of the base end portion 26 of the nozzle body 21 . This maintains the vacuum of the suction path (fitting hole 25, upper suction hole 26a, lower suction hole 27b) inside the suction nozzle 20 in which the nozzle body 21 slides up and down.

6 and 8A, a groove 31 is formed downward from a lower end 29c of the contact surface 29a on the side surface 22b of the nozzle body holding portion 22 in which the long hole 29 is formed. In FIG. 6, the bottom surface 31a of the 31 groove portion is inclined downward toward the outside of the nozzle body holding portion 22. As shown in FIG. 8A, the groove portion 31 is positioned below the center of the nozzle body holding portion 22 in the circumferential direction of the long hole 29, and the width W1 of the groove portion 31 in the circumferential direction of the nozzle body holding portion 22 is equal to that of the pin 30. smaller than diameter W2.
