A clutch mechanism (23, see fig 2) for use with an automatic door operation unit (2) for a vehicle, the clutch mechanism comprising: an input drive 231 element for connection to a drive unit; an output drive element 232 for coupling to a door 3 to drive movement of the door between an open and a closed configuration; and a resilient biasing system 233 to bias the input drive element and the output drive element into engagement such that rotation of the input drive element drives the output element, wherein the engagement is such that: a rotational force greater than a first force in a first direction will cause the input drive element to slip on the output drive element; and a rotational force greater than a second force in a second direction will cause the input drive element to slip on the output drive element, wherein the first force is less than the second force. The input and output drive elements may include one or more recesses (231e, see fig 10) which may have inclines, configured to engage one or more protrusions (232c) to engage with each other.
