To provide a water-cutoff rubber ring for the wrist which prevents liquid from flowing down to the arm along the hand when washing the face or brushing teeth and makes the liquid drop down at the portion of the wrist.

The water-cutoff rubber ring for the wrist is put on the wrist to prevent the drip of the liquid, and is provided with a guard having warpage at its outline part not to make the liquid come over the rubber ring so as to make the liquid drop down at the wrist. A lug is formed at one side of the relatively large ring so as to make it easy to wear the rubber ring at a single hand, and the lug is pulled up while pressing the ring with the thumb picking up the lug so as to be fixed to an optimum position with a Velcro (R) or the like.
