LATCH DEVICE
摘要:
To obtain a latch device for obtaining a great output load with a small input load.Holding parts (70) are provided on one end of holding members (64), and cam parts (72) are provided on the other end of the holding members (64), with a support part (68) of the holding members (64) as reference, and the cam parts (72) are moved away from each other by way of a rod (74), whereby the holding parts (70) are moved closer to each other. That is, the magnitude of the external force acting on the cam parts (72) can be changed by the movement of the rod (74), and the holding force of the holding parts (70) can therefore be changed with the support part (68) as a fulcrum. In other words, the stroke of the rod (74) and the position of the support part (68) of the holding member (64) are changed, and the distance from the support part (68) to the holding part (70) is made longer than the distance from the support part (68) to the cam parts (72).
