PURPOSE:To shift a load via a gear and by means of a rotary shaft serving as a power source, by applying a slight amount of trigger input. CONSTITUTION:A minor gear 2 is fixed to a rotary shaft 1, and a rotary wheel 6 is supported rotatably by a support shaft 6a. A lever 10 is held by guide pins 12 and 12a planted to the main body of a load shifting device and the slits 11 and 11a so that it can move approximately to or apart from the shaft 1. At the same time, the lever 10 is energized by a spring 13 having a comparatively small force to the direction approaching to the shaft 1. A gear cam 4 is supported rotatably by a support shaft 4a planted to the lever 10. A lever 14 is supported so as to turn up and down by a bearing provided to the main body of the shifting device with the projected parts 14a and 14b across the lever 14 serving as the support shafts. The lever 14 is energized light to the upper part by a spring. |
