Claim 1:
2. The input device according to claim 1,
wherein a length of the short arm and a length of the long arm are determined to satisfy a lengthwise relationship to reduce the inclination of the operation member obtained by adding
a first inclination of the operation member caused by a shortage, with respect to an amount of a vertical movement of one of the pair of secondary shafts closer to the short arm when a portion of the operation member closer to the short arm is pushed down, of an amount of a vertical movement of the other of the pair of secondary shafts closer to the long arm resulting from a shortage of a rotation angle of the long arm with respect to a rotation angle of the short arm due to distortion of the at least one inclination preventive member, and
a second inclination of the operation member caused by a vertical backlash of a shaft support portion of the at least one inclination preventive member when the portion of the operation member closer to the short arm is pushed down.
