Steering switch pad apparatus

摘要

A steering switch pad apparatus is disclosed. It has a cam plate rotable together with a steering wheel, at least two pins movable in the axial direction according to the rotation of the cam plate, a pin holder having through-holes for guiding the pins, and a base having holes for receiving the pins therein. A part of the pins in the position where a boss plate passes are retreated into the pin holder and at least one pin in the other position are pushed forward into the corresponding hole of the base by the cam plate during the rotation of the steering wheel, so that the pin holder and the base are held in the relatively standstill state irrespective of the rotation of the steering wheel. A power transmission mechanism for the above is also disclosed.
