The drive member is received at least partially within the housing for rotation about an axis relative to the housing between a first position and a second position. The retainer has a first position in which rotation of the drive member is prevented and a second position in which rotation of the drive member is permitted. At least one of the retainer and the drive member moves relative to the housing in a direction different from the rotation of the drive member so that the path of motion of the retainer between the first position and second position of the retainer is different from the path of motion of the drive member between the first position and second position of the drive member. ## Claims ### Claim 1 A park lock release actuator, comprising: a housing; a drive member received at least partially within the housing for rotation about an axis relative to the housing between a first position and a second position; and a retainer having a first position in which rotation of the drive member is prevented and a second position in which rotation of the drive member is permitted, and wherein at least one of the retainer and the drive member moves relative to the housing in a direction different from the rotation of the drive member so that the path of motion of the retainer between the first position and second position of the retainer is different from the path of motion of the drive member between the first position and second position of the drive member, wherein the retainer is fixed to the drive member, and the drive member is movable axially relative to the housing. ### Claim 2 (depends on 1) The actuator of claim 1 wherein the drive member has a tool engaging feature coaxial with the axis of rotation of the drive member. ### Claim 3 (depends on 1) The actuator of claim 1 wherein the retainer moves relative to the drive member. ### Claim 4 (depends on 3) The actuator of claim 3 wherein the retainer moves one of axially or radially or rotates/pivots relative to the drive member. ### Claim 5 (depends on 1) The actuator of claim 1 wherein the retainer has a cam surface that displaces the retainer from the first position to the second position as the drive member is rotated. ### Claim 6 (depends on 1) The actuator of claim 1 wherein the retainer is fixed to the drive member, and the housing includes a cam surface that engages the retainer to, as the drive member is rotated, drive the drive member in said direction different from rotation of the drive member. ### Claim 7 (depends on 1) The actuator of claim 1 which also comprises a cable having a conduit and a core received within the conduit, and the core is connected to the drive member so that the core is moved relative to the conduit when the drive member rotates relative to the housing. ### Claim 8 (depends on 1) The actuator of claim 1 which also comprises a biasing member that opposes movement of at least one of the retainer and the drive member in said direction different from rotation. ### Claim 9 (depends on 8) The actuator of claim 8 wherein the retainer is fixed to the drive member and the biasing member engages the drive member. ### Claim 10 (depends on 8) The actuator of claim 8 wherein the retainer moves relative to the drive member and the biasing member acts on the retainer. ### Claim 11 (depends on 1) The actuator of claim 1 wherein the retainer is carried by the housing and the drive member includes a stop surface selectively engageable with the retainer when the retainer is in the first position and the drive member is in the first position. ### Claim 12 (depends on 11) The actuator of claim 11 wherein the drive member includes a second stop surface engageable with the retainer when the retainer is in the first position and the drive member is in the second position. ### Claim 13 A park lock release actuator, comprising: a housing; a drive member received at least partially within the housing for rotation about an axis relative to the housing between a first position and a second position; and a retainer having a first position in which rotation of the drive member is prevented and a second position in which rotation of the drive member is permitted, and wherein at least one of the retainer and the drive member moves relative to the housing in a direction different from the rotation of the drive member so that the path of motion of the retainer between the first position and second position of the retainer is different from the path of motion of the drive member between the first position and second position of the drive member, wherein the housing includes a first void in which the retainer is received when the drive member is in its first position, and a second void in which the retainer is received when the drive member is in its second position. ### Claim 14 A park lock release actuator, comprising: a housing; a drive member received at least partially within the housing for rotation about an axis relative to the housing between a first position and a second position, and the drive member has a tool engaging feature coaxial with the axis of rotation of the drive member; and a retainer having a first position in which rotation of the drive member is prevented and a second position in which rotation of the drive member is permitted, and wherein at least one of the retainer and the drive member moves relative to the housing in a direction different from the rotation of the drive member so that the path of motion of the retainer between the first position and second position of the retainer is different from the path of motion of the drive member between the first position and second position of the drive member, wherein the retainer is carried by the drive member. ### Claim 15 (depends on 14) The actuator of claim 14 wherein the retainer is carried by the housing.
