Abstract
To prevent a decrease in detection accuracy of an obstacle that occurs when an obstacle detection distance of an infrared beam at the center is set longer than an infrared beam of at least one of the left or the right, an obstacle detection device for a vehicle which detects an obstacle in front includes an effective-range control partwhich controls the maximum effective distance of obstacle detection. The effective-range control partextends the maximum effective distance of the second emitting-and-receiving partsdisposed on at least one of the left or the right from an initial value Lto an extended value Lwhen the first emitting-and-receiving partat the center detects an obstacle
