Document Type and Number:
Japanese Patent JP6662272
Kind Code:
B2
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.
