Abstract: In a pulley apparatus, belt supporting portions of belt support pieces, which support a belt from a radially inside thereof, are arranged along a circumferential direction of a power shaft and each have a predetermined circumferential length. In a pulley driven mode, the belt support pieces rotate about corresponding first supporting members in a direction making the belt supporting portions become closer to the power shaft with second supporting members being relatively moved in corresponding elongated holes toward radially outer ends thereof, causing the belt supporting portions to be reduced in radius. In a pulley driving mode, the belt support pieces rotate about the corresponding first supporting members in a direction making the belt supporting portions become further from the power shaft with the second supporting members being relatively moved in the corresponding elongated holes toward radially inner ends thereof, causing the belt supporting portions to be increased in radius.

Abstract: A starter for an engine is provided which includes an electromagnetic brake device and a pinion thrust mechanism. The electromagnetic brake device holds a planetary carrier from rotating. The pinion thrust mechanism converts rotational motion of an internal gear into linear motion of a pinion when the rotation of the planetary carrier is locked. The pinion thrust mechanism includes a cylindrical cam cylinder, a starter housing, a thrust collar rotatable relative to the pinion, and an engaging pin. The cam cylinder is joined to the internal gear and has a circumferential extending cam groove. The starter housing has a straight groove traversing the cam groove. The engaging pin engages both the cam groove and the straight groove and is moved linearly with rotation of the cam cylinder. This enables the linear movement of the pinion regardless of a helix angle of the spline mounted on the output shaft.

Abstract translation: 提供一种用于发动机的起动器，其包括电磁制动装置和小齿轮推力机构。 电磁制动装置保持行星架不旋转。 当行星架的旋转被锁定时，小齿轮推力机构将内齿轮的旋转运动转换为小齿轮的直线运动。 小齿轮推力机构包括圆柱形凸轮缸，起动器壳体，可相对于小齿轮旋转的止推环和接合销。 凸轮缸连接到内齿轮上并具有周向延伸的凸轮槽。 起动器壳体具有横过凸轮槽的直槽。 接合销与凸轮槽和直槽啮合，并随着凸轮缸的转动而线性移动。 无论安装在输出轴上的花键的螺旋角如何，都能实现小齿轮的直线运动。
