  • Skateboard truck
    Patent number: 4103917
    Abstract: A wheel housing is resiliently mounted on a skateboard truck base by means of a fastener which extends through the housing and is threaded onto a stud fixed to the base to compress a tubular cushion between the housing and the base. The fastener has a square cross-section which mates with a square bore in the cushion so that rotation of the fastener with respect to the cushion is prevented except when the retainer is manually forceably rotated to adjust the compression on the cushion.
