摘要： A breather chamber structure for an internal combustion engine wherein the breather chamber can be disposed compactly and the degree of freedom in the layout of the parts of the internal combustion engine can be raised. The breather chamber structure includes a crankcase, a cylinder body provided upwardly on the crankcase, and a breather chamber configured to separate oil from oil mist in the crankcase. The breather chamber includes a crankcase side breather chamber provided in the crankcase and open to a joining plane between the crankcase and the cylinder body, and a cylinder side breather chamber provided in the cylinder body and open to the joining plane.

摘要： Provided is a routing structure for a braking force-transmitting member in a motorcycle in which a front part of a unit-swing engine supporting a rear wheel is supported on a vehicle body frame via a link mechanism, and the braking force-transmitting member is routed to extend in the fore-and-aft direction so as to transmit a braking force to a rear wheel brake disposed coaxially with the rear wheel, wherein the link mechanism includes a first link linked to the vehicle body frame and a second link linked to the unit-swing engine while having an engine suspension boss portion pivotably linked to the first link, and a guide member retaining the braking force-transmitting member extending in the fore-and-aft direction beneath the unit-swing engine is mounted on the second link. This can suppress swinging of a braking force-transmitting member and enables the mass around the braking force-transmitting member to be concentrated.
摘要翻译： 本发明提供一种摩托车中的制动力传递部件的布线结构，其中，支撑后轮的单位回转发动机的前部经由连杆机构支撑在车体框架上，制动力传递部件 被布置成沿前后方向延伸，以便向与后轮同轴设置的后轮制动器传递制动力，其中，所述连杆机构包括连接到车体框架的第一连杆和连接到车身框架的第二连杆 所述单位摆动发动机具有可枢转地连接到所述第一连杆的发动机悬架凸台部分，并且保持在所述单回转发动机下方沿前后方向延伸的制动力传递部件的引导部件安装在所述第二 链接。 这可以抑制制动力传递部件的摆动，并且使制动力传递部件周围的质量集中。
