Abstract
An electric-component mounting head, including a support member, a suction nozzle which applies a suction to an electric component and thereby holds the component, and a nozzle holder which is supported by the support member, which holds the nozzle such that the nozzle is movable relative to the support member in a direction parallel to an axis line of the nozzle, and which comprises a housing and a piston fitted in the housing such that one of the housing and the piston that is connected to the nozzle is movable relative to the other of the housing and the piston that is connected to the support member, the nozzle holder having at least one pressure chamber which is defined by at least one of axially opposite end surfaces of the piston and the housing, at least one communication opening which communicates with the one pressure chamber, two guide surfaces which are supported by the housing and the piston, respectively, and cooperate with each other to guide the relative movement of the housing and the piston, and a gas-supply passage which opens in a space provided between the two guide surfaces, at at least two positions axis-symmetric with each other with respect to an axis line …
