Provided is a throttle device configured so as to prevent an increase in the amount of valve leakage caused by the wear of the valve body or the valve seat. A throttle device has: a first support section (8) which comprises a through-hole for allowing a valve element body section (5) to penetrate therethrough and then through a valve chamber (14) and which supports a valve element (4) while being in sliding contact with the valve element body section (5); and a second support section (9) in which a refrigerant flow passage (13) and a valve element support hole (12) are formed, the refrigerant flow passage (13) connecting a second flow passage (3) and an orifice (11), the valve element support hole (12) allowing a valve element tip cylindrical section (7) to be fitted therein, and which is configured so that the valve element support hole (12) supports the valve element (4) while being in sliding contact with the valve element tip cylindrical section (7). |
