PROBLEM TO BE SOLVED: To provide a synthetic resinous slide bearing capable of reducing a friction to a radial load, and making steering operation further light.SOLUTION: A slide bearing 1 is equipped with a synthetic resinous upper case 2; a synthetic resinous lower case 3; and a synthetic resinous thrust side bearing piece 4 arranged between the upper vase 2 and the lower case 3. An annular void space 42 communicated with a slide clearance 42a and a plurality of recessed grooves 30 and regulated by an outer peripheral surface 9 and a tapered surface 24a, is formed between the upper case 2 and the lower case 3. The annular void space 42 and the recessed grooves 30 opening in the slide clearance 42a and communicating with the annular void space 42, are filled with a lubricant agent such as grease. Between radial slide bearing surfaces on the outer peripheral surface 9 and an inner peripheral surface 19, the lubricant agent supplied from the recessed grooves 30 and the annular void space 42 is always interposed. |
