PROBLEM TO BE SOLVED: To prevent a nozzle member from turning in a direction around a shaft, by fitting a buffer member to a nozzle part in the direction around the shaft to stop its turn, providing an engagement part for one end, providing a restraint part engaged with the engagement part for the trailing end of the nozzle member, and engaging the engagement part with the restraint part. SOLUTION: A part installation head is provided with a nozzle part 23 and a nozzle member 22 which is inserted into the nozzle part 23 through a buffer member 501 so that it can be attached/detached and attracts the part at the tip. The buffer member 501 is fitted to the nozzle part 23 in the direction around the shaft so that it cannot turn, and an engagement part 320 is provided for one end. A restraint part 221 engaged with the engagement part is provided for the trailing end of the nozzle member 22. The engagement part 320 of a spline shaft 32 is depressed to the restraint part 221 of the nozzle member 22 with the energizing force of a compression spring 24, and the engagement part 320 and the restraint part 221 are engaged. Thus, the turn of the nozzle member 22 in the direction around the shaft is prevented and the nozzle member 22 is positioned in the direction around the shaft. |
