ABSTRACT:
A linear scale type measuring device wherein an index scale mounted on a slider is opposed to a linear scale, the displacement of a movable member is imparted to said slider through connecting means and the relative displacement between the linear scale and the index scale is read by use of a light source and a receptor element both of which are provided on the slider, characterized in that said connecting means comprises a first engageable member provided at the forward end of a cantilever spring for biasing the slider toward the linear scale and a second engageable member engaging said first engageable member, and one of said first and second engageable members is formed into a projection or a recess provided with a tapered surface and the other is formed into a hole engageable with the tapered surface of said projection or cornered portion engageable with the tapered surface of said recess, said hole or the cornered portion being made of a ring-like portion which the forward portion of said cantilever spring is bent into.
