Patent ID: 8759654

Claim:
A musical instrument holding angle adjusting apparatus, comprising: a holding rod; and a clamping element that supports the holding rod so as to be axially rotatable and tiltable upward and downward, wherein the musical instrument holding angle adjusting apparatus adjusting a holding angle of a musical instrument held on one of the holding rod side and the clamping element side, and an increased diameter portion having an outer circumferential surface greater in diameter than the holding rod is provided at an outer circumferential portion on a base end side of the holding rod, wherein the clamping element includes: paired movable blocks arranged above and below the increased diameter portion of the holding rod to axially and rotatably receive the holding rod; a tightening collar including a substantially C-shaped ring portion as seen sideways, the ring portion being externally attached to each of the paired movable blocks to receive the movable blocks rotatably about an axis being perpendicular to an axis of the holding rod; and diameter reducing means for reducing a diameter of the ring portion of the tightening collar, wherein by the diameter reducing means reducing the diameter of the ring portion, the paired movable blocks become incapable of rotating in a state clamping the increased, diameter portion of the holding rod, whereby a top to bottom tilt angle and an axial rotation angle of the holding rod are fixed.
