A steplessly adjustable shoulder rest for violin or the like includes an elongated
base having two oppositely spaced recesses provided on an upper surface thereof.
Two guiding and locking bolts are separately located at and projected from an outer
side of a center of the two recesses to engage with long slots on two adjusting
slides, so that the adjusting slides are slidably located in said recesses. Outer
ends of the two adjusting slides are two vertical end walls, to outer sides of
which two binding elements are screwed to move along with the adjusting slides.
Two nuts are tightened to or loosened from the two guiding and locking bolts upward
projected from the adjusting slides, so the adjusting slides may be steplessly
adjusted to desired positions for the binding elements to best fitly connect the
shoulder rest to a lower rear end of the violin or the like.
