PURPOSE: A bumper for a snowplow is provided to improve the durability of a snow-removing plate while the angle of the snow-removing plate is adjustable by an angle adjusting bar, and a return spring facilitates the operation of the angle adjusting bar. CONSTITUTION: In the upper and lower sides of the rear side of a snow-removing plate(10), connecting parts(12) having a hinge groove(11) are formed. A fixture(13) is formed at the upper end of the snow-removing plate, and a control plate(14) is installed in the central part to control the lift of a stopper(60). A main frame(20) is placed in the rear area of the snow-removing plate, and has an installation part(22). The main frame has a locking member(23) in the lower side, and is connected to a mounding plate. An angle adjusting bar(40) is installed between the installation part and the connecting part by a hinge shaft(41), and adjusts the angle of the snow-removing plate. A return spring(50) is installed between the fixture and the locking member, and controls the operation of the snow-removing plate. The stopper is formed in the lower side of the main frame, and fixes the location of the snow-removing plate at the bottom of the control plate.
