Claim:
A strainer, comprising: a base element that is fixed on a shell body side of a drum; a snare assembly holding element that is engaged with the base element to freely slide up and down, and that has its bottom end side connected to a snare assembly; an operating lever that slides up and down the snare assembly holding element relative to the base element, so as to switch the snare assembly between contact and noncontact states relative to a drumhead, characterized in that the strainer further comprises a link that pivotally and rotatably support a pedestal end side of the operating lever on the base element via a shaft portion, the link having its one end rotatably connected to a site located lower than the shaft portion of the operating lever in the snare assembly holding element, the link having its other end also rotatably connected to a midway position away by a prescribed distance toward a tip end from the pedestal end portion of the operating lever, wherein upward rotation of the operating lever lifts up the snare assembly holding element relative to the base element via the link, and downward rotation of the operating lever pushes down the snare assembly holding element similarly via the link.
