と、このスリーブの外周に偏心回転可能に被嵌さ
れた回転軸受と、上記スリーブと回転軸受との間
に充填され回転軸受のスリーブに対する回転抵抗
体としての粘性オイルと、上記回転軸受の外周に
回転自在に被嵌されたローラと、上記回転軸受を
上記ローラの外側に架設されたベルトに向かつて
付勢する付勢部材とを具備したオートテンシヨナ
において、上記スリーブの外周面または回転軸受
の内周面の少なくともいずれか一方に凹凸面を形
成したことを特徴とするオートテンシヨナ。 a fixed shaft, a sleeve fitted on the outer periphery of the fixed shaft so as to be rotatable in one direction via a one-way clutch, a rotary bearing fitted on the outer periphery of the sleeve so as to be eccentrically rotatable, and a rotating shaft that rotates with the sleeve. viscous oil filled between the bearing and the sleeve of the rotary bearing as a rotational resistor; a roller rotatably fitted around the outer periphery of the rotary bearing; and a belt extending between the rotary bearing and the outside of the roller. What is claimed is: 1. An autotensioner comprising a biasing member that biases the sleeve toward the shaft, wherein an uneven surface is formed on at least one of the outer circumferential surface of the sleeve and the inner circumferential surface of the rotary bearing.
