。The bearing 6 of the hook type joint is formed by surrounding a bushing 9, a solid lubricant piece 10, and a small disk 11 with a cup 12, and the journal 5 (!: The inner surface of the hole of the bushing 9 in contact with the bushing 9 has a protruding sliding surface. A solid lubricant piece 10 that fits into the grooves 8 holds the axis of the journal 5 so that it can shift together with the sliding surface 7, and the journal 5. This bearing has a structure that absorbs minute vibrations and vibrations, and is characterized in that the position and amount of clearance between the bottom of the stepped groove 8 and the solid lubricant piece 10 change depending on changes in the direction of torque and load.
