摘要： Provided are a power transmission switching mechanism allowing reduction in size and weight in a simple configuration with a minimized piece-part count, and a transmission provided therewith. The power transmission switching mechanism includes a sleeve that moves in an axial direction of a rotation shaft, a hub section provided integrally with a gear for holding a sleeve axially slidably and unrotatably, and a dog spline installed to a pulley piston fixed to the rotation shaft for meshing the sleeve. In a state in which the sleeve is held to the hub section, the rotation shaft is disengaged with the gear and a relative rotation thereof is allowed. Meanwhile, when the sleeve axially moves from the hub section, the rotation shaft engages with the gear and both thereof rotate integrally.

摘要翻译： 提供一种动力传递切换机构，其能够以简单的结构减小尺寸和重量，同时具有最小的零件数量以及与其一起提供的变速器。 动力传递切换机构包括沿旋转轴的轴向移动的套筒，与用于将套筒轴向滑动和不可旋转地保持的齿轮一体地设置的轮毂部分，以及安装到固定到旋转轴的滑轮活塞上的狗花键 用于啮合套筒。 在套筒保持在轮毂部的状态下，旋转轴与齿轮脱离啮合并允许其相对旋转。 同时，当套筒从毂部轴向移动时，旋转轴与齿轮接合，并且它们都一体地旋转。
