Abstract: A wire fixing structure includes: a first hole portion through which a wire passes; and a second hole portion which is formed in a direction orthogonal to the first hole portion and communicates with the first hole portion. The wire includes: a first portion which is inserted into and is disposed in the first hole portion; a second portion which is extended from the first hole portion and wound around the outer peripheral portion of a wire fixing member; and a third portion which is inserted into and is disposed in the first hole portion again after the second portion is wound around the outer peripheral portion. The fastening member is inserted into the second hole portion and fixes the first portion and the third portion by pressing in the first hole portion.
