ABSTRACT:
Disclosed are a multi-directional input key and a key input device helping to suppress erroneous input through the input key and providing a satisfactory operability. The multi-directional input key has an operation portion, on which are formed rectifying protrusions adapted to come into contact with the circuit board before the board contacts are brought into conduction upon tilting the operation portion to thereby rectify the tilting attitude of the operation portion toward the normal tilting direction. Even when the key top is tilted in an oblique direction deviated from the normal tilting direction, the rectifying protrusions come into contact with the upper surface of the printed circuit board before the board contacts are brought into conduction to thereby rectify the tilting direction of the key top to the normal tilting direction.
