Drive mechanism of two degrees of freedom

A power transmission unit of a drive mechanism has a link mechanism on both sides of a base portion. The link mechanism has a first link member having a base end portion provided to the base portion to be rotated about a third rotational axis, a second link member having a base end portion connectin...

Beschreibung
Zusammenfassung:	A power transmission unit of a drive mechanism has a link mechanism on both sides of a base portion. The link mechanism has a first link member having a base end portion provided to the base portion to be rotated about a third rotational axis, a second link member having a base end portion connecting the first link member's distal end portion to be rotated about a fourth rotational axis, and a third link member which is provided to a driven body to be rotated about a fifth rotational axis and to which the second link member's distal end portion is provided to be rotated about a sixth rotational axis orthogonal to the fifth rotational axis. 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.
