To solve the problem that it is inconvenient when operating buttons in an operation part while holding a remote control apparatus nearly horizontally, in a remote control transmitter of a home electrical appliance (television, DVD player, CD player) or the like.

A rotary type transmission device installed at a distal end of a remote controller keeps the remote control apparatus horizontally regardless of inclination of the remote controller. Therefore, an operator easily operates the remote controller while inclining the distal end of the remote controller to a side of the operator.
