Abstract
In a linear scale type displacement measuring instrument including: a case fixed to one of relatively movable members; a main scale; a carriage; index scales and a detector; the carriage and the other of the relatively movable members are connected to each other through a connecting mechanism, one end of which is connected to the carriage, the other end of which is connected to the other of the relatively movable members in a location where a section standard length of the main scale is maintained as it is when the main scale is straight, i.e. within the neutral planes of the case as a whole including the main scale mounted, and capable of permitting the carriage to change the posture thereof such that the index scales can be held in a state of perpendicularly intersecting the normal line of the surface of a warp of the main scale.
