PROBLEM TO BE SOLVED: To provide a self-propelled cleaner capable of detecting a colliding direction in a simple structure using a single sensor. SOLUTION: On the side face on the front side of a main body 1, a bumper 2 in a prescribed length in the side face direction of the main body 1 is installed roughly centering the front of the main body 1. The bumper 2 is composed of a side face part covering the side face, an upper surface part partially covering a main body upper surface, and a lower surface part partially covering a main body lower surface. The bumper 2 is supported by a support member 3 composed of a spring or the like roughly at the center and is fixed to the side face of the main body 1. Further, an acceleration sensor 4 is fixed on the side of the main body 1 of the upper surface part of the bumper 2 and the acceleration sensor 4 is electrically connected to a control part inside the main body 1. When the bumper 2 collides with an obstacle, though the bumper 2 is displaced, an impact is suppressed by the support member 3 and the main body 1 is protected. By the displacement of the bumper 2, an acceleration corresponding to a collision is detected in the acceleration sensor 4. COPYRIGHT: (C)2005,JPO&NCIPI
