<P>PROBLEM TO BE SOLVED: To provide a balancer device capable of reliably preventing a resin cover from separating when the resin cover is arranged at an eccentric mass part and the contour is formed approximately symmetric about a balancer shaft. Ž<P>SOLUTION: A fixing member 20 having recesses 21 and 22 extending parallel with the balancer shaft 1 is formed extending from the eccentric mass part 2 integrally, and the resin cover 3 is insert molded so that a filling part 30 is formed where the recesses 21 and 22 are filled. During rotation, the filling part 30 is engaged with the fixing member 20 to reliably prevent the resin cover 3 from separating off the eccentric mass part 2. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
