摘要： In a transmission, an inner end portion in a radial direction of a washer abuts on an inner race of a first bearing, and a seal surface provided on an outer end in the radial direction of the washer abuts on an outer race of a second bearing. Therefore, load in an axial direction which acts on a second gear can be supported with a second rotary shaft via the outer race of the second bearing, the washer and the inner race of the first bearing. Additionally, on a side surface at the second bearing side, of the washer, a lubricating oil guide surface is formed, that guides lubricating oil which is supplied from an inside of a second rotary shaft, to a one-way clutch through the second bearing, and therefore, a lubricating effect can be enhanced by efficiently supplying the oil to the second bearing and the clutch.

摘要： If a sleeve of a double cone-type synchronizer is not smoothly engaged with a dog gear because of getting caught by the dog gear, the dog gear, as pressed by the sleeve, may lean with a spline-connecting part of the dog gear to a transmission gear as a fulcrum, so that an inner ring of a blocking ring may be damaged by being squeezed between the dog gear and a hub. However, the transmission gear includes: a tooth surface portion having tooth surfaces formed on one axial end side of the transmission gear; and a contact portion formed on the opposite axial end side, and abutting against the dog gear. The contact portion extends radially outward of a through-hole of the dog gear, thereby preventing the dog gear, as pressed by the sleeve, from leaning toward the transmission gear so as to prevent damage of the inner ring.

摘要翻译： 在变速器中，垫圈的径向内端部与第一轴承的内圈抵接，并且设置在垫圈径向外端的密封面与第二轴承的外圈抵接 。 因此，通过第二轴承的外圈，垫圈和第一轴承的内圈，可以通过第二旋转轴来支撑作用在第二齿轮上的轴向的负载。 此外，在垫圈的第二轴承侧的侧面，形成有将从第二旋转轴的内部供给的润滑油引导到通过第二轴承的单向离合器的润滑油引导面 因此，通过有效地向第二轴承和离合器供给油，可以提高润滑效果。
