A conveying means (1) is described having running rollers (7) which can be supported on a guide (2). At least one running roller (7) is mounted on a roller lever (12a) which can be pivoted between a first and a second position with the aid of a pivoting mechanism (13, 33) and can be locked in a position. In order to make a conveying means of this type simpler in structural terms and less susceptible to wear, it is proposed to equip the pivoting mechanism (13, 33) with a toggle lever (14) which is connected to an actuating element (21), wherein the toggle lever comprises a first and a second lever element (14a, 14b) which are connected to one another via a joint (15).
