摘要： The invention relates to a power transmission mechanism between an engine starting device and an engine. A side surface shape of a lever-shaped engaging and disengaging member (107) in a side facing to a ratchet wheel (120)of a rotation driven portion is formed in a concave shape concaved in a direction away from the wheel (120). The lever-shaped engaging and disengaging member (107) is engaged with and disengaged from a centrifugal clutch mechanism of the engine engaging with and disengaging from the ratchet wheel (120). A first engaging and disengaging lever (141) is engaged with the ratchet wheel (120), a sufficient force to start the engine is accumulated in a force accumulating power spring (131), thereafter the engagement of the first engaging and disengaging member (141) is disconnected by a manual operation, and the ratchet wheel (120) is rapidly rotated by releasing the accumulated force in the force accumulating power spring (131). When the ratchet wheel (120) starts rotating at this time, a stop position of the lever-shaped engaging and disengaging member (107) is not determined, and it is often the case that the lever-shaped engaging and disengaging member (107) and the rapidly rotating ratchet wheel (120) are not originally in the engaged state. As a result, leading ends of the engagement surfaces come into collision with each other so as to be broken, and it is hard to start the engine. However, the lever-shaped engaging and disengaging member (107) is not broken on the basis of the shape and the structure peculiar to the invention, and it is possible to securely start the engine regardless of the stop position thereof and an abrasion of the first engaging and disengaging lever (141).

摘要翻译：本发明涉及发动机起动装置和发动机之间的动力传递机构。在与旋转驱动部分的棘轮（120）相对的一侧中的杠杆形接合和分离构件（107）的侧表面形状形成为沿远离轮（120）的方向凹陷的凹形形状。杠杆式接合和分离构件（107）与发动机的离心式离合器机构接合并与其脱离啮合并与棘轮（120）脱离啮合。第一接合和分离杆（141）与棘轮（120）接合，起动发动机的足够的力被累积在力存储动力弹簧（131）中，此后第一接合和分离构件（141）的接合）通过手动操作断开，并且棘轮（120）通过释放蓄力电动弹簧（131）中的累积力来快速旋转。此时棘轮120开始转动时，不能确定杆状卡合脱离构件（107）的停止位置，通常情况下，杠杆状卡合脱离构件（107）并且快速旋转的棘轮（120）原本不处于接合状态。结果，接合面的前端彼此碰撞而被破坏，并且难以启动发动机。然而，根据本发明特有的形状和结构，杠杆式接合和分离构件（107）不会断裂，并且可以可靠地启动发动机，而不管其停止位置和第一接合和分离杆（141）。
