A rotary head 11 is attachably and detachably linked to a driving unit 41 of a component suction device 10, and a nozzle rotation gear mechanism 47 which transfers a rotating force of a Q-axis driving mechanism 20 of the driving unit 41 to each nozzle holder 12 is provided in the rotary head 11. The nozzle rotation gear mechanism 47 is configured by meshing a cylindrical gear 48 which is held to be rotatable by the rotary head 11 and small gears 49 which are attached to each nozzle holder 12, and forms a positioning projection portion 53 in an upper end portion of the cylindrical gear 48. In a Q-axis gear 21 of the Q-axis driving mechanism 20 of the driving unit 41, a nipping mechanism 43 is provided to nip the positioning projection portion 53, and when linking the rotary head 11 to the driving unit 41, as the positioning projection portion 53 is nipped by the nipping mechanism 43, the cylindrical gear 48 is linked to the Q-axis gear 21 in a rotating direction by eliminating looseness. |
