PURPOSE: To simplify design and construction for fixing numerous fluid ejecting heads by providing a supply junction chamber housed inside a housing a taking-in port formed on a circumferential wall, and a plurality of supply ports formed on a side wall, for sending the fluid to the fluid ejecting heads.
CONSTITUTION: A junction unit U for a fluid ejecting head is provided with two cylindrical portions 1a, 1b each having different diameters to constitute a housing 1, and accordingly, a supply junction chamber 2 is formed as a whole. Water supply ports 1ab... as supply ports arranged at equal intervals in the circumferential direction are formed on a circumferential wall of the cylindrical portion 1a. A downward water supply port 1bb is formed on a bottom wall 1ba in the lower cylindrical portion 1b. A water taking-in port 1bc as a taking-in port for introducing fluid from a water supply main pipe and a spare water supply port 1ba are formed on the side wall of the cylindrical portion 1b. A connecting cylindrical portion 4, which is projected outward, is disposed continuously to an opening edge of the water taking-in port 1bc on the side wall of the cylindrical portion 1b, for connecting the water supply pipe.
