Abstract

PURPOSE:To prevent a malfunction for detecting an obstacle, due to direct propagation, by providing a projection on the end part of a vehicle provided with an ultrasonic transmitter and an ultrasonic receiver, and obstructing the direct propagation of an ultrasonic wave to the ultrasonic receiver from the ultrasonic transmitter. CONSTITUTION:Between an ultrasonic transmitter 1a and an ultrasonic receiver 1b installed to a vehicle end part 2 such as a bumper, etc., a projection 2a is provided, and by this projection 2a, direct propagation of an ultrasonic wave to the receiver 1b from the transmitter 1a is obstructed. Therefore, in case of its obstacle detecting operation, side lobes 4a in each 90 deg. direction of the transmitter 1a and the receiver 1b are obstructed by the projection 2a, or are reflected in the direction other than 90 deg., and it is possible to prevent a malfunction due to direct propagation of an ultrasonic wave to the receiver 1b from the transmitter 1a.
