PROBLEM TO BE SOLVED: To provide a water flow detector that can slow down opening operation of a valve body without requiring complicated control.SOLUTION: Inside of a cylindrical body 1 is divided into a primary side chamber I and a secondary side chamber II with a partition wall 12. The cylindrical body 1 includes a valve body 2 of a check valve structure which is capable of opening/closing a communication port 13 drilled in the partition wall 12; and a switch device which operates by detecting the opening of the valve body 2. The body 1 is configured to connect a cylinder 6 sliding along the inner wall of the body 1 to the valve body 2 by means of a flexible member 66. |
