Claim:
A strainer system of a snare drum, the snare drum including upper and lower drumheads, the upper drumhead being beaten in playing the snare drum, the strainer system switching the position of a snare wire between an OFF position spaced from the surface of the lower drumhead and an ON position in contact with the surface of the lower drumhead, the strainer system comprising: a frame to which the snare wire is attached, wherein the frame extends along the surface of the lower drumhead and has a pair of end portions, and wherein the frame includes a pair of rods arranged in parallel and a pair of hooks fixed to the rods; a pair of link mechanisms, each one of the pair of link mechanisms being joined to a respective one of the end portions of the frame, and attaching the respective one of the end portions of the frame to a shell of the snare drum; and an operating section that is operated for switching the position of the snare wire between the OFF position and the ON position, wherein the operating section is provided in either one of the pair of link mechanisms, wherein one of the link mechanisms includes a first link member fitted to a first end portion of the frame, and the other of the link mechanisms includes a second link member fitted to a second end portion of the frame, wherein each of the link members include a pair of L-shaped arms and a cross link between the arms, and wherein the pairs of arms pivot about respective positions above the lower drumhead and extend downward relative to the upper drumhead, the pairs of arms being configured to pivot toward the center of the snare drum and to extend below the lower drumhead so that the cross links engage the hooks, the pairs of arms disengaging the cross links from the hooks by pivoting outward relative to the center of the snare drum.
