Provided is a nozzle mounting structure (106) of a component container by which a nozzle configured to rotate between a first position and a second position may be mounted to a housing without the need for a high processing precision and a high assembly precision. A pair of shaft portions (166) support a body (161) with the nozzle (105) unitarily formed therewith. The nozzle (105) rotates between the first position and the second position. A curved convex surface (162) provided on the body is pressed against a curved concave surface (136) provided on a first bottom wall portion (135) of a housing (103) by a pressing force imparted from a support portion.
