Abstract:
PROBLEM TO BE SOLVED: To provide a faucet device which can switch flow passages easily, which is small and which has excellent reliability.SOLUTION: A faucet device 300 includes a water discharge part 302, a first flow passage and a second flow passage. The water discharge part 302 includes a switching valve V1 for switching flow passages, an operation part 320, and a thrust lock mechanism 330 for connecting the operation part 320 and the switching valve V1. The switching valve V1 has a first valve part VG and a second valve part VJ. By the thrust lock mechanism 330, the operation part 320 can take a jump-out position, a push-in position and a maximum push-in position. A valve seat surface has a front facing valve seat surface M1. When the operation part 320 is in the push-in position, a closed state is achieved by a seal member provided at the first valve part VG or the second valve part VJ coming into contact with the front facing valve seat surface M1 from front. A buffer mechanism is provided which includes a stretchable elastic body which expands/contracts according to a movement amount of the operation part 320 from the push-in position to the maximum push-in position.SELECTED DRAWING: Figure 8
