A horizontal adjustment-engagement member (33) of an object detection device (D) drives the horizontal rotation component (32) to adjust a horizontal angle of a detection unit (11, 12), and a vertical adjustment-engagement member (37) drives the vertical rotation component (36) to adjust a vertical angle of a detection unit. Both adjustment-engagement members (33 and 37) are positioned adjacent to each other at fixed positions such that portions thereof are exposed on a front surface of the device (D), are removably engaged with an external automatic angle adjustment unit (70) from front surfaces, and are automatically adjusted by a driving force of the automatic angle adjustment unit (70) based on a signal level of a detection signal outputted by level output section (7). |
