• a radial bearing surface formed on an inner peripheral surface of the main body portion;
• a thrust bearing surface formed on one end surface of the main body portion in an axial direction of the shaft;
• an oil hole, which is formed on a side of the main body portion opposite to the thrust bearing surface with respect to the radial bearing surface, and penetrates from the inner peripheral surface of the main body portion to the outer peripheral surface of the main body portion;
• and
• a communication hole, which has one end opened in a gap between the outer peripheral surface of the main body portion and an inner peripheral surface of the bearing hole or in the damper portion, and has another end opened on only an innermost side of the thrust bearing surface in a radial direction of the shaft.
