Abstract
A traction drive power transmission device, where a lubrication oil can be stably and continuously applied for a long period to portions at which rollers and a shaft are in contact with each other, shortage of the lubrication oil does not occur at the contact portions, the lubrication oil is not wasted, and which does not impair work environment by contaminating floor surface etc. A traction drive power transmission device has at least one drive roller (), a follower roller (), and a circular cylinder-like shaft (). The shaft () is held between the drive roller () and the follower roller (). When the drive roller () is rotated, rotational force by the rotation is transmitted to the shaft () to drive it in its axial direction. The device has a lubrication oil-delivering portion () with application bodies (--) for applying a lubrication oil only to portions where the shaft () is in contact with the drive roller () and the follower roller ().
