NARROW GAP INSPECTION DEVICE

摘要

[Problem] To provide a narrow gap inspection device for a concrete bridge which can conduct wide range image-pickup in a narrow gap by using an image pickup means. [Solution] A main body (4) is provided with a mirror (12) that reflects an inspection location, a lighting means (14) that lights the inspection location, and an image pickup means (11) that picks up an image of the inspection location reflected by the mirror (12). The main body (4) is formed longer in the length direction than the thickness direction and longer in the width direction which intersects the length direction. The mirror (12) is set at an incline with respect to the length direction, the length dimension (W1) of the mirror (12) in the width direction is greater than the dimension in the length direction. Due to this configuration, the inspection device, when inserted into a narrow gap (102), makes it possible to pick up an inspection location reflected by the mirror (12) by the image pickup means (11), and at such time, to pick up an image over a wide surface area because the length dimension (W1) in the width direction of the mirror (12) is greater than the length dimension.
