Abstract: The present invention relates to a variable valve mounted on a pipe to be opened or closed in accordance to pressure of discharged gas. The variable valve includes a closing plate mounted inside the pipe and having an opening hole perforated to block the flow of the discharged gas; a spring manufactured with elastic material and coupled to the closing plate; and a gate mounted to block the opening hole by elasticity of the spring, wherein the spring has two leg portions coupled to the closing plate from each end and a connection portion connecting the leg portions and coming in close contact with the gate, and the leg portions are twisted in the connection portion in different directions. Different from a conventional structure wherein a shaft, which is a rotary shaft of the gate, is disposed outside the pipe, the gate is opened and closed inside the pipe, thereby considerably reducing noise transferred outside when opening and closing the gate. The gate occupies small portion inside an internal space of a muffler, thereby reducing sizes of both the variable valve and peripheral parts.
