Abstract

In a joystick device where a tilting operation direction of an operation shaft is detected based on positional change of a magnet relative to a magnetic sensor, the magnet being moved with tilting of the operation shaft, a slider (59) is arranged between a base (60) facing a board (61) fixed to a case (17) and a magnet holder (58) to which the operation shaft (16) is swingably coupled; the magnet holder (58) is joined to the slider (59) such that the slider (59) guides relative movement of the holder (58) in a first linear direction orthogonal to the axis of the operation shaft (16) but prevents relative movement of the holder (58) in a second linear direction orthogonal to the first direction; and a guide mechanism configured to guide movement of the slider (59) in the second direction is provided between the slider (59) and the base (60). This prevents variation in the detection accuracy by keeping constant a distance between the magnet and the sensor regardless of tilting of the shaft.

Description

technical field [0001] The present invention relates to a joystick device. The joystick device includes: an operating handle; an operating shaft, one end of which is connected to the operating handle; a shaft capable of tilting from a neutral position around a tilting center set on the axis of the operating shaft; a magnetic sensor provided on a substrate fixed to the case; and a magnet The operation shaft is formed to move according to the tilting movement of the operation shaft, and the magnet is arranged to face the magnetic sensor, and the joystick device detects the operation shaft based on a change in the relative position of the magnet with respect to the magnetic sensor. The direction of the tilt motion operation. Background technique [0002] For example, Patent Document 1 discloses a joystick device in which a magnet is provided at the other end of an operation shaft provided with an operation handle at one end so as to face a magnetic sensor provided on a substra...
