PROBLEM TO BE SOLVED: To provide a sensor axial deviation detection device and method of detecting sensor axis deviation capable of detecting axial deviation among plural sensors even when not every sensors can detect identical object with a simple constitution.SOLUTION: The sensor axial deviation detection device includes a first sensor (10) and a second sensor (20) which are adapted to detect an identical object, and when an object existing in a first detection region (21) of a first sensor exists in preset cover area (22) of the second sensor but it is determined as not exist in the second detection region (21), the sensor axial deviation detection device determines that an axial deviation is generated between the first sensor and the second sensor. |
