ABSTRACT:
The present invention relates to a caster (1), in particular a steering roller having a wheel (5, 6) and a locking device, the locking device having a setting element (7) and engagement element (9) which cooperates with the setting element so as to block the travel of the wheel (5, 6) in which a linear setting movement of the setting part (7) can be transmitted via a wedge transmission (10) to the engagement element (9). In order to achieve a development which is as simple as possible from a design standpoint and also has advantageous kinematics, the invention proposes that the engagement element 9 be arranged guided for linear movement in order to effect a linear engagement movement with respect to the wheel (5, 6).
