摘要

Provided is a water passage switching device that can be built in a small space. A water passage switching device of the present invention includes a rotational lock member pivotable between a locking position and an unlocking position; a plurality of operation cams moved between initial and pressed-down positions; a plurality of operation members that opens and closes valve elements; and an engaging portion that is formed to extend from the rotational lock member and holds the operation cam at the pressed-down position, wherein, when a first operation cam of the plurality of operation cams is pressed, the engaging portion is pushed to pivot the rotational lock member from the locking position to the unlocking position, thereby returning a second operation cam kept at the pressed-down position to the initial position, and when the first operation cam is pressed to the pressed-down position, the rotational lock member is returned to the locking position to keep the first operation cam at the pressed-down position.
