PURPOSE: An automatic angle adjusting unit for an object detecting device is provided to easily and automatically adjust an angle from the outside by having a detachable structure in a small size and at low costs. CONSTITUTION: An angle adjusting device(30) has a horizontal angle adjusting part(31) and a perpendicular angle adjusting part(35). The horizontal angle adjusting part comprises a perpendicular rotary motion member(32) which drives each optical system(12) in a rotary motion in the horizontal direction; and a horizontal adjusting dial(33) capable of fitting by being engaged with the automatic angle adjusting unit of the outside. The perpendicular angle adjusting part comprises a perpendicular rotary motion member(36) which drives each optical system in a rotary motion in the perpendicular direction; and a perpendicular adjusting dial(37) capable of fitting by being engaged with the automatic angle adjusting unit of the outside by being engaged with a con rod(36). The optical system is accommodated in the con rod which is a perpendicular rotary motion member. |
