内燃機関のバランサ軸駆動装置。[Scope of Claim for Utility Model Registration] (1) A gear chamber is formed in a casing that is fixed to the engine body, and a driven gear is fixed to one end of a balancer shaft that is rotatably supported by the engine body, and the balancer shaft. A driving gear provided at the inner end of a rotary shaft rotatably supported by the casing in parallel with the drive gear and meshing with the driven gear is housed in the gear chamber, and the outer end of the rotary shaft protruding from the casing is wound. In a balancer shaft drive device for an internal combustion engine that is interlocked and connected to a crankshaft via a hanging transmission system, the casing has a lubricating oil discharge hole that communicates the lower part of the gear chamber with the engine body, and an opening to the gear chamber. A balancer shaft drive device for an internal combustion engine, characterized in that the lower end edge of the end is disposed at a position equal to or higher than the lowest end of the lower gear of the drive gear and the driven gear. (2) The balancer shaft drive device for an internal combustion engine according to item (1), wherein the outer diameter of the lower gear of the driving gear and the driven gear is set larger than the outer diameter of the upper gear. (3) The lubricating oil discharge hole is located at a position corresponding to a position between the disengagement position of both gears and the lowest end position of the lower gear along the rotation direction of the lower gear of the driving gear and the driven gear, The balancer shaft drive device for an internal combustion engine according to item (1) or item (2), characterized in that it is bored in the casing.
