Abstract

In a joystick device, a rotation position detector for detecting a rotation position of a rotatable cylinder having one end coupled with a dial knob is provided between the cylinder and a case. The detector includes a drive gear provided around the cylinder, a rotary body which has a driven gear provided around its outer periphery and is in mesh with the drive gear, multiple magnets provided on the rotary body, and a magnetic sensor provided in the case to face one end portion of the rotary body to detect the rotation position of the cylinder based on positional change relative to the magnets along with rotation of the rotary body. Such arrangement enhances the degree of design freedom for arranging a magnetic sensor in the axial direction of the cylinder in detecting a rotation position of the cylinder by the sensor and reduces a necessary number of magnets.
