PURPOSE: To suppress undesirable vibration that may be generated at the time when a shower equipment is turned on and off, wigh regard mainly to the draining device of the shower equipment.

CONSTITUTION: This device is constituted of packing 13 attached on the downstream side of an inlet 11 of water, a first outlet 14 on the downstream side of the packing 13, a second outlet 15 opened and closed by the packing 13, on the downstream side of the packing 13, and a spring 16 for energizing the packing 13 so as to open a second outlet 15, and constituted so that in the case pressure of water which goes into the inlet 11 of water exceeds set pressure, the packing 13 is pressed down by hydraulic pressure and a second outlet 15 is closed, and also, in the case the pressure becomes below the set pressure, a second outlet is opened by energizing of the spring 16, and moreover, a moving variation of the packing 13 at that time is suppressed small by a space ring, by which even in the case vibration is generated, a moving range of the packing 13 is limited and an abnormal sound comes not to be generated.
