The present invention provides, in order to improve assemblability and durability, a wire tightening device comprising: a base body part having an accommodation partition part provided at the upper surface part thereof; a reel part rotatably disposed inside the accommodation partition part such that a wire is selectively wound thereon during rotation; a housing part including a coupling partition part of which the lower end part is coupled to the accommodation partition part and which has a ratchet-shaped gear protruding from the upper end part of the inner periphery thereof, and a dividing plate protruding inwards in a radial direction along the lower part of the ratchet-shaped gear so as to restrict the upper end of the reel part, and having a lifting hole formed at the center part thereof; a lifting gear part including a gear body part coupled so as to be lifted and lowered along the lifting hole and rotate integrally with the reel part when the gear body part is lowered, and having a mounting step protruding from the outer periphery thereof, elastic wing parts provided on the outer periphery of the mounting step and coupled to the ratchet-shaped gear so as to restrict one-way rotation, and an extended lifting fixing part protruding from the lower surface part of the mounting step so as to be selectively and elastically supported by the upper and lower surfaces of the rim of the lifting hole; and a cover part coupled to the upper part of the lifting gear part so as to be lifted/lowered and rotated integrally with the same.
