Claim 2:
3. The input device according to claim 1,
wherein a formula {L1×SIN(θ1)=L2×SIN(θ1-θ2)−ΔH} is satisfied,
where L1 denotes a length of the short arm,
L2 denotes a length of the long arm,
θ1 denotes a rotation angle of the short arm when a portion of the operation member closer to the short arm is pushed down,
θ2 denotes a shortage of a rotation angle of the long arm with respect to the rotation angle of the short arm caused by distortion of the at least one inclination preventive member when the portion of the operation member closer to the short arm is pushed down, and
ΔH denotes a difference in height between the portion of the operation member closer to the short arm and a portion of the operation member closer to the long arm, due to 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.
