Claim 12:
13. A method of assembling a parking mechanism provided in a drive device, wherein
the parking mechanism includes
an actuator having a manual shaft extending along a first axis and rotating around the first axis,
a flange provided on an outer periphery of the manual shaft and extending along a radial direction of the first axis,
a cam rod including a coupling portion coupled to the flange, a rod body extending along a second axis orthogonal to the first axis and moving along the second axis and along with a movement of the flange, and a relay portion connecting the coupling portion with the rod body,
a sleeve into which a distal end of the rod body is inserted,
a coil spring attached to the rod body,
a cam that is attached to the rod body and moves along the second axis by motion of the rod body transmitting via the coil spring,
a pawl member having a meshing portion and operating with a movement of the cam, and
a parking gear having a tooth portion with which the meshing portion meshes,

the flange includes
a flange body extending along the radial direction of the first axis, and
a protruding portion that protrudes from the flange body in a direction parallel to the first axis, and

the protruding portion is disposed closer to the parking gear than the relay portion in an axial direction of the second axis and overlaps with the relay portion when viewed in the axial direction of the second axis,
the method comprising:
a cam rod coupling step of coupling the cam rod to the flange; and
a sleeve attaching step of attaching the sleeve, wherein

the sleeve attaching step is performed in a posture in which the second axis is disposed along a vertical direction, and includes supporting the relay portion from below by the protruding portion and inserting the distal end of the rod body into the sleeve.
