受を介してケースに支持されるシヤフトと、この
シヤフトに遊転自在に支持される第１ギヤと、こ
の第１ギヤに常時噛合う第２ギヤとを有する歯車

を最も広くしたことを特徴とする歯車装置。 A shaft supported by a case via a bearing having an oil groove bored in its inner diameter that communicates with a hydraulic power source, a first gear supported by the shaft for free rotation, and always meshing with the first gear. In a gear device having a second gear, the inner diameter of the bearing is larger than the outer diameter of the shaft by an amount equivalent to the backlash, and the width of the oil groove is on the second gear side in the direction connecting the centers of the first gear and the second gear. A gear device characterized in that the side opposite to the second gear is the narrowest, and the side opposite the second gear is the widest.
