Abstract

A water saving device having an installation cover (2) for installation on a faucet (1) etc., a water saving piece (6) installed within the installation cover (2) and having one or more water discharge holes (62), and a water-tight packing (3) for preventing water leakage from between the faucet (1) etc. and the installation cover (2). A pressure reduction piece (4) is placed between the installation cover (2) and the water saving piece (6), and the pressure reduction piece (4) has a flow path change hole (42) for forcibly changing the direction of water supplied from water discharge means, such as the faucet (1) etc., to reduce the pressure of the water.
