Description

そして、上述した固定軸３１の外径寸法ｄ３は、前述したボス部を兼用しているメタル軸受４２の外径寸法ｄ４よりも小さく設定されているが（ｄ３＜ｄ４）、その固定軸３１の外径寸法ｄ３と、メタル軸受４２の外径寸法ｄ４との間を含む所定の半径方向区間内において、上記メタル軸受４２の図示下端面側に、略山形状をなす軸受延長部４２ａが設けられている。 The outer diameter d3 of the fixed shaft 31 described above is set smaller than the outer diameter d4 of the metal bearing 42 also serving as the boss described above (d3 <d4). In a predetermined radial direction section including between the outer diameter dimension d3 and the outer diameter dimension d4 of the metal bearing 42, a bearing extension portion 42a having a substantially mountain shape is provided on the lower end surface side of the metal bearing 42 in the figure. ing.
