ジンのバランスシヤフト。[Claims for Utility Model Registration] (1) A counterweight is attached to one side with respect to the center of rotation, and the cross-sectional shape is such that the center of rotation and the center of gravity are eccentric, and the centrifugal force generated by rotation causes In an engine balance shaft designed to reduce unbalanced forces generated when the crankshaft rotates, the portion of the outer circumferential surface of the balance shaft facing the inner circumferential surface of the balance shaft bearing that is on the side of the counterweight with respect to the center of rotation. To,
A balance shaft for an engine, characterized in that an equalizing means is provided for equalizing stress acting from the outer circumferential surface portion to the inner circumferential surface of the bearing when the balance shaft rotates. (2) In the shaft according to claim (1) of the utility model registration, the equalizing means is the outer circumferential surface portion having substantially the same curvature as the inner circumferential surface of the bearing. balance shaft. (3) In the shaft according to claim 1, the equalizing means is configured to apply a large amount of water to the gap between the inner circumferential surface of the bearing and the outer circumferential surface of the balance shaft, which is faced by the outer circumferential surface. An engine balance shaft characterized by being a lubricating oil passage that supplies lubricating oil.
