Abstract
Provided is a throttle device to decompress a refrigerant cooled by a condenser in a refrigerating cycle and to deliver the refrigerant to an evaporator, where a minimum space between a needle valve and a valve port can be accurately set. Inside a cylindrical main body case including a primary chamber connected to the condenser and a secondary chamber connected to the evaporator, a valve seat member formed with a valve port and a cylindrical guide member integral to the valve seat member are provided. A coil spring to energize the needle valve toward the valve port side is provided inside the guide member. A needle portion of the needle valve protrudes from the valve port toward the primary chamber. A tip portion of the needle portion abuts against a stopper member and the tip portion is thereby positioned.
