Abstract
In a throttle device, a body portion has a flat surface at a position at a predetermined distance from its center axis. Thus, when a needle member is moving, a working pressure of a refrigerant present between an inner peripheral surface of a guide tube and the flat surface acts in a radial direction of the body portion and presses part of an outer peripheral surface of the body portion located opposite from the flat surface against the inner peripheral surface of the guide tube.
