Claims

[Scope of utility model registration request]

A rotating shaft portion, a pair of arm portions protruding from both ends of the rotating shaft portion in a direction intersecting the rotating shaft portion, and a tip of the arm portion protruding in a direction substantially parallel to the rotating shaft portion. The rotating shaft of the interlocking rod is rotatably supported on the lower surface of the key for operating the switch, and the guide shaft of the interlocking rod is integrally formed with the guide shaft. A key parallel operation device for a key switch that is slidably inserted into a guide groove in a direction substantially perpendicular to the direction of the key depression operation, the key having an opening for introducing a guide shaft portion at one end of the guide groove;
and a key parallel operation device in a key switch, characterized in that the lower surface of the key is provided with a guide for regulating the angle of the interlocking rod, which tilts the arm portion in a direction in which the guide shaft portion faces into the guide shaft introduction opening portion. .
