This balancer for an internal combustion engine comprises upper and lower housings 3, 4 inside of which an accommodating part 10 is provided, a pair of drive and driven shafts 5, 6 which are rotatably supported in four plain bearings 11-14 provided in the accommodating part and to which rotational force is transmitted from a crankshaft, and arcuate belt-shaped thrust-receiving parts 32a, 33a to which thrust flanges of respective drive and driven gears 8, 9 provided to the shafts are capable of coming in contact from a thrust direction. First oil-accumulating grooves 34, 35, groove passages 36, 37, and vertical groove passages 38a-39b are provided to the gravitationally lower sides of the portions of the thrust-receiving parts that mesh with the gears.
