A forgotten display body, and a guide member having a guide surface supported by the faucet body below the forgotten display body and abutting against a lower end surface of the forgotten display body. The guide surface of the member has a first position where the lower end surface of the forget-to-tighten display abuts when the handle is in the closed position, and a lower end surface of the forget-to-tighten display when the handle is in the fully open position. And the first position is different from the first position in height It has a position, in which flow channel opening and closing state is visible by protruding state from the handle top wall of Shime忘 Re display unit in the first position and the second position.

According to the faucet of this invention, the handle is turned from when the handle is in the closed position, that is, when the lower end surface of the forgotten-tight display body is in contact with the first position of the guide surface of the guide member. By setting it to the fully open position, the forgotten-tightened display body moves with it, and its lower end surface contacts the second position of the guide surface of the guide member. Since the first position and the second position have different heights, the amount of protrusion of the forget-to-tighten display body from the top wall of the handle changes, and the opening and closing of the flow passage is performed by the state of protrusion of the forget-to-tighten display. You can know the status.

[0007] A first stopper that engages with the forget-to-tighten display body when the handle is turned clockwise on the guide surface of the guide member, and a table that does not close when the handle is turned counterclockwise. It is preferable that the second stopper and the second stopper to be engaged with the indicator are provided in a protruding shape, respectively. In this way, a proper closed position and a proper full-open position are ensured, and there is no overtightening or opening more than necessary.

An annular inwardly projecting portion is provided at an upper and lower intermediate portion of the vertical through hole of the handle top wall, and between the inwardly projecting portion and a spring receiving member fitted over the lower end of the forgotten-tight display body. Further, it is preferable that a spring for urging the forgotten tightening display body downward is interposed. In this way, the display of the forget-to-tighten indicator is stopped, and the smooth vertical movement of the forget-to-tighten indicator is ensured.

Preferably, the guide surface is formed so as to be flat before the fully open position. In this case, a certain amount of force is required to rotate the handle from the fully open position to the closed position, and the handle is rotated to the closed position only when an object or hand hits the handle in the fully open position. Is prevented.
