Autonomous traveling body

An autonomous traveling body, comprising:

• a main body case that includes a main body part and a bumper arranged at an outer edge of the main body part;
• a driving wheel that enables the main body case to travel;
• a link mechanism that connects the bumper to be movable in a relatively horizontal direction with respect to the main body part;
• a bumper energizing body that energizes the bumper in a direction separated from the main body part;
• a pair of obstacle detectors that is arranged at positions facing the bumper in the main body part respectively and that detects an obstacle by detecting movement of the bumper, due to contact with the obstacle, in at least one of a direction opposite to an energizing direction of the bumper energizing body and a direction crossing the direction;
• and
• a controller that controls drive of the driving wheel based on detection of the obstacle by the obstacle detectors to allow the main body case to travel autonomously,
• wherein the bumper energizing body energizes the bumper in a direction opposite to a moving direction of the bumper in case the bumper moves in a direction other than the direction opposite the energizing direction of the bumper energizing body.
