Abstract
A motor includes a casing and a holder which support a rotation shaft. A concave groove is formed in the holder near the inner periphery of the holder. The concave groove accommodates a positive temperature coefficient thermistor functioning as an overcurrent protection device. A tapered cutout surface is formed on the outer wall of the holder so that the cutout surface is inclined at 45 degrees with respect to a line passing through the rotation shaft and the groove portion of the holder has a maximum length of the holder in its axis direction. A multi-direction input device includes these two motors functioning as driving sources to provide a force feedback to an operation lever. The first and second motors are disposed such that lines passing through their rotation shafts are orthogonal to each other and cutout surfaces are opposed to each other with an intersection of the lines therebetween.
