Vehicle inspection device

A vehicle inspection device that adjusts a sensor axis of a first external environment sensor in a vehicle in which the first external environment sensor that acquires external environment information is attached to a vehicle body, the vehicle inspection device comprising:

• a moving body including a reflector that reflects an electromagnetic wave emitted from the first external environment sensor, and an electromagnetic wave characteristic measurement device that measures characteristics of the electromagnetic wave emitted from the first external environment sensor;
• and
• a control device that controls the moving body,
• wherein the control device calculates an attachment position of the first external environment sensor and a direction of the sensor axis on the basis of electromagnetic wave characteristics measured by the electromagnetic wave characteristic measurement device, and moves the moving body to an inspection position that is determined on the basis of the calculation result.
