Abstract
The distal structure of a leg for a musical instrument stand is constituted of a spike member installed inside the storage of a case having a ground portion whose ground surface is placed on the floor, a rotor interconnected to the spike member, and a single operator projected above the case. Upon a first depression, a presser of the operator depresses a projection of the rotor downward so that the spike member protrudes from the ground surface. In the protruded state of the spike member, the projection of the rotor is engaged with a receptor formed in a stepped interior of the storage. Upon a second depression, the presser of the operator depresses the projection of the rotor again so as to release the engagement between the projection and the receptor, so that the spike member moves to retract inside the storage of the case.
