In the bearing mechanism, an oil storage chamber is formed between the outer periphery of the rotating shaft and a collar having a discharge hole in the center is inserted and fixed onto the rotating shaft, and the collar is inserted into the notch of the radial bearing. A bearing mechanism characterized in that the bearing is provided with an inward diagonal passage that is engaged with the collar to prevent axial movement of the bearing, and that communicates with the supply port and supplies lubricating oil to the collar.
