Abstract
A transfer device includes a first parallel four-joint link mechanism in which base end portions of a pair of first links are rotatably connected to a first link base and distal end portions of the first links are rotatably connected to an intermediate link base, a second parallel four-joint link mechanism in which base end portions of a pair of second links are rotatably connected to the intermediate link base and distal end portions of the second links are rotatably connected to a second link base, and a belt transmission mechanism including a pair of first pulleys respectively connected to the first links, a second pulley connected to one of the second links, and a belt provided around the first pulleys and the second pulley. The belt transmission mechanism transmits a rotational driving force such that the first links and the second links rotate in opposite directions to each other.
