ABSTRACT:
A castor includes a castor body, two rollers rotatably mounted on the castor body and each having an annular toothed locking section, a locking member movably mounted on the castor body and having two locking flanges each having a toothed engaging portion, and a brake handle pivotally mounted on the castor body to drive the toothed engaging portion of each of the locking flanges of the locking member to engage the toothed locking section of the respective roller. Thus, when the brake handle is pressed to stop rotation of the rollers, the resting face of the pivot base abuts the support rib of the castor body so that the brake handle is operated smoothly and stably without producing vibration during operation of the brake handle, thereby enhancing the braking effect of the castor.
