PROBLEM TO BE SOLVED: To inhibit wear of a slide member from being caused by foreign objects taken into a gap between a rotary shaft and a bearing.SOLUTION: A bearing mechanism has a slide member 42, which rotatably supports a rotary shaft 14 with an outer peripheral surface of the rotary shaft 14 slidably contacting therewith and thereby enabling the slide member 42 to support the rotary shaft 14, on an inner peripheral surface of a bearing case 41 having a cylindrical shape. The slide member 42 includes slide pieces 43 which protrude to the inner side in a radial direction and are provided along a circumferential direction. The slide member 42 is formed so that the slide pieces 43 protruding to the inner side in the radial direction are set to different protruding positions.SELECTED DRAWING: Figure 7 【課題】回転軸と軸受との隙間に取り込まれた異物による摺動部材の摩耗の発生を抑制すること。【解決手段】円筒状の軸受ケース４１の内周面に、回転軸１４の外周面が摺接することで回転軸１４を回転可能に支持する摺動部材４２を有する軸受機構において、摺動部材４２は、半径方向内側に突出すると共に周方向に沿って複数設けられた摺動片４３を有し、当該摺動片４３の半径方向内側への突出位置を異ならせて形成される。【選択図】図７
