PROBLEM TO BE SOLVED: To provide a pinion oil-feed type power transmission device 1 which can uniformly and automatically feed lubrication oil to a pinion 6, and is achieved in the labor-saving of oil feed work.SOLUTION: A compression coil spring 15 is arranged, an impregnation member 14 is made to slide-contact with a pin roller 7 by the energization force of the spring, and thereby the pin roller 7 slide-moves on the lower face 14d of the impregnation member 14 accompanied by the rotation of the pinion 6. Accordingly, since the lubrication oil is fed to the pin roller 7 from the impregnation member 14 of an oil feed part 12, the lubrication oil can automatically be fed to the pinion 6 by a necessary amount when necessary. By this, the automatic feed of the lubrication oil is enabled, and the wasteful use of the lubrication oil is eliminated different from the case that grease or the like is coated on the pinion 6 by hand work, thus achieving the labor-saving of the oil feed work.
