Abstract
In a direction control valve, a bottom face of an insertion hole of a first movable member is at a predetermined distance from a second movable member with respect to a first axial direction when communication between a first communication switching port and a communication object port is made and communication between a second communication switching port and the communication object port is broken. The bottom face contacts and pushes the second movable member in a second axial direction opposite to the first axial direction after the first movable member moves in the second axial direction by the predetermined distance while the first and second movable members move in the second axial direction to switch a port communicating with the communication object port from the first communication switching port to the second communication switching port.
