    • A lubrication structure for a multi-speed transmission has a lubrication structure in which a gear shaft is provided with cam guide grooves in an inner cavity thereof. A lubricating oil is introduced into the inner cavity by way of oil feed introducing holes which are bored in one end portion of the gear shaft so as to provide communication between the inside and the outside of the gear shaft. The lubricating oil is led in the axial direction along the inner peripheral surface of the inner cavity by axial oil feed grooves formed by cutting along the inner peripheral surface of the inner cavity in parallel to the cam guide grooves. The lubricating oil is led out to the engagement switch-over mechanism by radial oil feed holes bored in radial directions so as to communicate with the axial oil feed grooves at axial-direction positions where pin members are located.
    • 用于多速变速器的润滑结构具有润滑结构,其中齿轮轴在其内腔中设置有凸轮引导槽。 润滑油通过在齿轮轴的一个端部中钻孔的供油引入孔引入内腔,以便在齿轮轴的内部和外部之间提供连通。 润滑油通过沿着内腔的内周面与凸轮引导槽平行切割而形成的轴向供油槽沿着内腔的内周面在轴向上被引导。 润滑油通过沿径向方向钻孔的径向供油孔被引导到接合切换机构,以便在销构件所在的轴向位置与轴向供油槽连通。
