A flow rate regulator of a unit structure, in which the mechanism keeps constant the amount of injection of the contents in an aerosol container independent of a variation in pressure of gas for content ejection. The flow rate regulator unit has an outer sheath member (15), an inner sheath member (16), piston members (17, 18), a coil spring (25), and an ejection piece (19). The contents are ejected in substantially the following route: “hole (15a)—annular space region (21) for outer path—hole (16a)—annular space region (22) for inner path—holes (17b, 18b)—inside path (18c)—valve action region (20)—penetration section (16d)—groove-like sections (16f, 19a)—ejection hole (19c).” An annular skirt section (17a) moves in the left-right direction based on a magnitude relation between force in the right direction caused by ejection gas pressure and acting on the piston members (17, 18) and urging force to the left direction caused by the coil spring (25), and this changes an inflow cross-sectional area from the hole (16a) for flow rate adjustment to the annular space region (22) for inner path.

1. A flow rate regulator unit mounted in a casing section, comprising: a piston member, including an inner content passage inside the piston member, an opening in a sidewall of the piston member which is in fluid communication with the inner content passage, and an outwardly extending skirt on the sidewall of the piston member, the piston member movable from a forward position to a rearward position in response to pressure of content spraying gas in an aerosol container;a holding part, including an internal space for accommodating said piston member, where said piston member is movable, a hole in a sidewall of the holding part for allowing a content in the aerosol container to flow into a flow rate adjusting space located between said hole and the outwardly extending skirt of the piston member, the opening in the sidewall of the piston member being in fluid communication with the flow rate adjusting space when the piston member is in the forward position and the outwardly extending skirt blocking the fluid communication between the opening and the flow rate adjusting space when the piston member is in the rearward position, a receiving section for receiving a front end of the piston member, acting valve function therewith, and a mounting section on the sidewall of the holding part for connecting the holding part to a stem of the aerosol container; andan elastic member positioned between a rear end of said piston member and an inner rear end surface of said holding part for energizing said piston member in the forward position;wherein the holding part is a separate member from the casing section, and the casing section is composed of a single member which is movable in a downward direction, toward the aerosol container by a pressing operation by a user, andwherein the flow rate regulator unit is a unit structure independent from the casing section, and the flow rate regulator unit is mounted in the casing section and on said stem. 2. An aerosol product, comprising the flow rate regulator unit mounted in the casing section according to claim 1.
