A screen equipment that can effectively remove alien substances caught on the screen by moving the rake projections upward in the state that rake projections are accurately inserted into contaminated water passing openings of a screen is provided. A screen equipment comprises: a body frame(10) installed on a waterway; a screen(11) which is installed along upper and lower parts of an inner side of the body frame, and on which contaminated water passing openings(P) are formed; upper and lower sprockets of which each pair are installed on upper and lower portions at both sides of the body frame; a pair of chains(17) connected to the upper and lower sprockets in a closed loop shape and rotatably circulated; and rakes(20) of which longitudinal both sides are connected to both of the chains, and which have rake projections(23a) corresponding to the contaminated water passing openings, wherein rake position setting guides are installed on both of the lower sprockets(30) to set positions of the rakes such that the rake projections are inserted into the contaminated water passing openings of the screen. The rake position setting guides are formed in a ring shape on the periphery of a shaft coupling part(31) of the lower sprockets and have chamfered guide surfaces formed on regions where longitudinal both ends of the rakes contact.
