フト。[Claims for Utility Model Registration] 1. A balance shaft that rotates around an axis to reduce vibrations of an internal combustion engine, comprising a bearing part supported by a bearing, and extending from the bearing part along the axis,
In the balance shaft of an internal combustion engine, the balance shaft of an internal combustion engine is provided with an eccentric mass part formed at a part eccentric from the shaft center, and an end of the eccentric mass part opposite to the bearing part is a free end. A rib extending from the bearing portion toward the free end is formed on the side surface, and the rib has a length of approximately 1/3 to 1/2 of the length of the eccentric mass portion, and the rib extends toward the free end. A balance shaft for an internal combustion engine, characterized in that it is formed low and smoothly connects to the above-mentioned surface at the free end side portion. 2. The balance shaft according to claim 1, wherein the rib has a cross-sectional shape that becomes wider as it approaches the surface. 3. The balance shaft according to claim 1, wherein the ridgeline of the rib has a gentle slope as it approaches the free end side portion.
