A power transmission unit of a drive mechanism (1) has a link mechanism (10) on both sides of a base portion (3). The link mechanism (10) has a first link member (11) having a base end portion provided to the base portion (3) so as to be rotated about a third rotational axis (A3), a second link member (12) having a base end portion connected to a distal end portion of the first link member (11) so as to be rotated about a fourth rotational axis (A4), and a third link member (13) which is provided to a driven body (2) so as to be rotated about a fifth rotational axis (A5) and to which a distal end portion of the second link member (12) is provided so as to be rotated about a sixth rotational axis (A6) orthogonal to the fifth rotational axis (A5). A desired operation angle range of two degrees of freedom in a driven body can be ensured with a compact configuration while suppressing deflection of a structure to which the driven body is mounted.
