Joystick device

A joystick device comprising:

• an operation knob;
• an operation shaft coupled to the operation knob on one end thereof;
• a case supporting the operation shaft while allowing the operation shaft to tilt from a neutral position about a tilting center set on an axis of the operation shaft;
• a magnetic sensor provided on a board fixed to the case;
• a magnet arranged to face the magnetic sensor in such a manner as to move in accordance with the tilting of the operation shaft, in which a tilting operation direction of the operation shaft is detected based on positional change of the magnet relative to the magnetic sensor, wherein
• the board is fixed to the case in such a manner as to extend along a plane including a first linear direction and a second linear direction, the first linear direction being orthogonal to an axis of the operation shaft placed at the neutral position, the second linear direction being orthogonal to the axis of the operation shaft placed at the neutral position and to the first linear direction,
• a base is fixed to the case, the base facing the board and including a first opening portion which the magnetic sensor provided on the board faces,
• the magnet is fixed to a holding protruding portion which is provided on a magnet holder and is inserted into the first opening portion, the other end of the operation shaft being swingably coupled to the magnet holder,
• a slider is arranged between the magnet holder and the base, the slider including a second opening portion into which the holding protruding portion is inserted,
• the magnet holder is joined to the slider such that the slider guides relative movement of the magnet holder in the first linear direction but prevents relative movement of the magnet holder in the second linear direction, and
• a guide mechanism configured to guide a movement of the slider in the second linear direction is provided between the slider and the base.
