PROBLEM TO BE SOLVED: To sufficiently and correctly feed a grinding fluid to a grinding point without being affected by the rotational angle of a work. SOLUTION: A grinding fluid feeder comprises a lower side first link member 28 and an upper side second link member 34 with fixed support points 24 and 30 on one side and movable support points 26 and 32 on the other side, a third link member 36 pivotably supported on the movable sides of the first link member 28 and the second link member 34, a driving link member 40 with one end part pivotably supported by an intermediate part of the first link member 28 and the other end part pivotably supported in the vicinity of an outer circumferential surface of a disk part 46, and a nozzle 22 which is pivotably supported by a movable end of the first link member 28 and displaced following the positional change of the grinding point at which a pin part 54 of a rotating crank shaft 52 is brought into contact with a grinding wheel 14.
