An operational rod coupling arrangement includes a motion member constituting part of a motion mechanism, an operational rod having a coupling hole at one end to be pivotally coupled with the motion member for transmitting an operational force and a connecting member configured to clamp the end of the operational rod in cooperation with a portion of the motion member. One of the motion member and the connecting member includes a shaft portion and the other of the motion member and the connecting member includes a bearing portion in which the shaft portion is insertable. The shaft portion, extending through the coupling hole, is insertable into the bearing portion. An engaging portion and an engaged portion for preventing withdrawal of the shaft portion from the bearing portion are at different positions than the shaft portion and the bearing portion in the connecting member and the motion member, respectively.
