    Abstract: A direction stabilizer device for a castor type wheel (1) which is arranged to swivel about a swivel axis, the direction stabilizer device comprising a centrifugal means arranged to operate a locking mechanism to lock the wheel in a pre-set orientation about the swivel axis, when the wheel (1) is rotated. The direction stabilizer device is arranged such that the locking mechanism operates to lock the wheel in the pre-set orientation only when the wheel (1) is rotated above a pre-defined speed. The direction stabilizer device is also arranged such that the rotation of the wheel (1) causes the centrifugal means to rotate, such rotation operating the locking mechanism.
