Abstract
A displacement measuring appparatus is small in size and hence capable of avoiding interference with other units and further has its measurement accuracy hardly deteriorated. There are disposed pulleys for movement with respect to the body of the appartus and there is disposed an energizing means such that the pulleys are subjected to the energizing force. A wire is passed around the pulleys. When the wire is subjected to a pulling force, the pulleys are moved against the energizing force of the energizing means.
