<p>The present application provides a battery-replacing robot (5) capable of appropriate replacing a battery (3) in a vehicle (2) even if said battery (3) is located at a comparatively low point in the vehicle (2). Said robot (5) is provided with: a battery insertion/removal mechanism (17) that removes and inserts batteries (3) from and into vehicles (2); a holding member (26) that holds said battery insertion/removal mechanism (17); and a raising/lowering mechanism (18) that raises and lowers said holding member (26). The battery insertion/removal mechanism (17) is provided with a movable part (22) that, in order to insert or remove a battery (3), moves towards the vehicle (2) and protrudes from the holding member (26) when inserting or removing a battery (3). The raising/lowering mechanism (18) is provided with a first raising/lowering mechanism (59) and a second raising/lowering mechanism (60) disposed respectively on both ends of the raising/lowering mechanism (18) with respect to a first direction that is orthogonal to both the direction in which the movable part (22) moves and the up-down direction.</p>
