a sensor that detects a tilt angle;
a display unit including a plurality of strip-shaped display members that emits light linearly by an LED and displays the tilt angle; and
a control circuit that receives a signal from the sensor and outputs a control signal so that a specific strip-shaped display member glows,
wherein the strip-shaped display members include one horizontal strip-shaped display member positioned at a middle of the display unit and a plurality of strip-shaped display members for tilt-angle display that has tips bent toward a center of the display unit, wherein each of the strip-shaped display members has an LED attached to an end, and a pair of strip-shaped display members provided to be point-symmetrical with respect to the center of the display unit simultaneously glows according to the tilt angle.
