Abstract
The present invention provides a flow channel switching valve with a reduced number of components as well as a reduced weight, and a method for assembling the same. A valve shaft adapted to be coupled to a valve element so as to transmit torque of a rotary drive portion to the valve element is inserted through a vertical through-hole, which penetrates through the valve element in the direction of the rotation axis O (i.e., vertical direction), and through a fit-insertion hole provided in a valve body. Then, a drive gear that forms the rotary drive portion is fixed to the upper coupling portion of the valve shaft protruding from the fit-insertion hole so that the valve shaft is rotatably supported with respect to the valve body.
