1. A touching detection device comprising:
a probe having a touched part, a support part supporting the touched part, and a sensed part, the touched part having a touch surface to be touched by an object to be detected;
a sensor sensing the sensed part of the probe; and
a body holding the probe and the sensor,
wherein:
the support part is held by the body to be swingable in a direction in which the object to be detected touches the touch surface of the touched part;
the sensed part is configured to be displaced in accordance with an amount of swing of the support part;
the sensor is configured to, when the sensed part is displaced by a preset displacement amount, sense the sensed part and output a detection signal;
the support part is configured to support the touched part via an angle adjustment mechanism configured to be able to adjust an angle of the touch surface in a swinging direction of the support part;
the touched part has two touch surfaces to be touched by the object to be detected, the touch surfaces being perpendicular to each other;
both the touch surfaces are flat;
the support part is held by the body to be swingable in each of two directions in which the object to be detected touches each of the touch surfaces of the touched part;
the sensed part is configured to be displaced in accordance with an amount of swing of the support part in each of the two directions;
the sensor is configured to, when the sensed part is displaced by a preset displacement amount in accordance with the amount of swing of the support part in each of the two directions, sense the sensed part and output a detection signal; and
the angle adjustment mechanism is configured to be able to adjust an angle of each of the touch surfaces in a corresponding swinging direction of the support part.
