Inside a stick base, a variable resistor and a magnet brake are attached to a turnable first bridge. An A/D converter adapted to convert an analog value corresponding to a turning angle, which is obtained from the variable resistor, to a digital value, and a controller adapted to drive the magnet brake when a signal from the A/D converter is given and coincides with a predetermined value are provided. On the basis of data retained in a memory, current is applied to a coil of the magnet brake. Doing so makes it possible to electrically change operational feeling when turning a stick.
