A drive force transmission device, a mechanical device, and a liquid ejection apparatus are provided to have a small-sized and simply-configured drive force transmission structure for transmitting drive force to plural driven members. A drive force transmission device includes a lead screw(31) and at least one movable member(41,42,43). The lead screw includes a thread portion formed on an outer circumference surface of the lead screw. The lead screw is rotated about an axis of the lead screw when a drive force is generated. The at least one movable member has an engagement portion, which is arranged to engage with the threaded portion of the lead screw. The movable member is moved along an axis direction of the lead screw through the engagement portion guided by the threaded portion when the lead screw is rotated. While the movable member is moving, the movable member associates with driven members in a state in which the drive force is transmitted from the lead screw to the driven members. |
