PROBLEM TO BE SOLVED: To provide a drinking water supplying apparatus capable of preventing drinking water from remaining in a passage from a water intake valve to a water intake opening on the downstream side after the water intake valve is switched to be closed by completion of water intake operation to a time when the water intake valve is switched to be opened by the next water intake operation. SOLUTION: A water outlet pipe 28 communicated with a valve room 272 of a cold water intake valve 27 is extended to the water intake opening 281. As the water outlet pipe 28, by intersecting an inclined passage part 286 and an outlet passage part 287, a bending part 282 bending by using a corner edge 283 as a boundary is equipped. A passage inner wall face 284 of the inclined passage part 286 on the upstream side placing the corner edge 283 between them is made to be an elevating slope, and a passage inner wall face 288 of the outlet passage part 287 on the downstream side is made vertically hung down. The water flow flowing down the passage inner wall face 284 is peeled off from the passage inner wall face 288 when it exceeds over the corner edge 283, and a vortex flow containing air is formed backward.
