|20120260763||JOYSTICK DEVICE - 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.||10-18-2012|
|20120260760||JOYSTICK DEVICE - 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 is arranged between a base facing a board fixed to a case and a magnet holder to which the operation shaft is swingably coupled; the magnet holder is joined to the slider such that the slider guides relative movement of the holder in a first linear direction orthogonal to the axis of the operation shaft but prevents relative movement of the holder in a second linear direction orthogonal to the first direction; and a guide mechanism configured to guide movement of the slider in the second direction is provided between the slider and the base. This prevents variation in the detection accuracy regardless of tilting of the shaft.||10-18-2012|
|20110083628||PLUGHOLE WATERPROOFING DEVICE FOR ENGINE - In a plughole waterproofing device for an engine, a coil case for covering an ignition coil is fitted onto the ignition coil that is accommodated, together with an ignition plug, in a plughole opened to an upper surface of an engine, and a longitudinal air path extending upward from a lower end portion of the case upper portion communicating with the plughole and a vent hole communicating with an upper end portion of the longitudinal air path and being opened to ambient air are provided in a case upper portion, protruding above the engine, of the coil case. The vent hole is provided in an upper portion of the case upper portion. A cover wall hanging while surrounding the vent hole is continuously provided on the case upper portion, and an air chamber is formed inside the cover wall, the vent hole being opened in an upper portion of the air chamber, an opening face being formed at an entire bottom of the air chamber in such a manner as to open toward the engine. Accordingly, it is possible to effectively prevent water intrusion into a vent hole and thus preventing a plughole from receiving water even when the engine receives water repeatedly.||04-14-2011|
