A component mounter (10), wherein disc parts (37) of adjacent nozzles (32) are spaced far enough apart so that a pressing roller (44) can pass therethrough vertically. It is therefore possible to make the disc parts (37) relatively small, and reduce the size of a rotary head (30). A horizontal protrusion (45) is of such size that when the pressing roller (44) is positioned between the disc parts (37) of adjacent nozzles (32), the horizontal protrusion (45) overlaps one or both of two annular protrusions (38) of the adjacent nozzles as viewed from above. Therefore, even if the power supply to a z-axis linear actuator (47) is cut and a raising/lowering member (42) unexpectedly loses support and falls when the pressing roller (44) is positioned above the gap between the disc parts (37) of adjacent nozzles (32), the horizontal protrusion (45) of the raising/lowering member (42) is received and stopped by the annular protrusion (38) of a nozzle (32). |
