A limit switch apparatus is provided to simply regulate a gap of limit switches by using a gap regulating unit installed in the inside of the limit switch apparatus, thereby performing safe and precise control. In a limit switch apparatus, a slide block(100) has a gap regulating unit for regulating a gap between limit switches(40a,40b) installed on the front and rear directions of a rotational axis(20), and a guide unit to slide the limit switches(40a,40b) with predetermined gaps when the gap regulating unit is fixed to a body(10). A bracket(200) has a female screw hole(220) in a vertical piece at the center thereof. A gap regulating bolt(300) penetrates front and rear side walls of the body(10) and is rotated while being fixed to a fixing washer(340). A male screw unit(320) is formed on the outer surface of the fixing washer(340) so as to be engaged with the female screw hole(220) of the bracket(200).
