<p>PROBLEM TO BE SOLVED: To provide a self-travelling electronic apparatus having improved performance for running onto a step part on a floor surface in a room.SOLUTION: A self-travelling electronic apparatus includes: a housing having a bottom plate; a pair of left and right driving wheel units for supporting the housing; and an elastic member for elastically energizing the driving wheel units in a direction protruding downward from the bottom plate. The driving wheel unit has: a driving wheel; and a driving wheel holder for holding the driving wheel rotatably around a first shaft center. The driving wheel holder is arranged further backward than the first shaft center, and mounted on the housing rotatably around a second shaft center parallel with the first shaft center. The self-travelling electronic apparatus is configured in such a manner that an energizing force of the elastic member is applied to the driving wheel units so that a pressing force which is vertical to a straight line connecting the first shaft center and the second shaft center, and which goes toward an outer peripheral direction of the driving wheel from the first shaft center faces further frontward in a travelling direction than the gravity direction of the housing.</p> |
