Abstract
A carrying device which can prevent an object to be carried from being contaminated with dust and carry the object to a correct position. The present invention is constructed by first and second parallelogram linkages. The second parallelogram linkage is formed by using a link of the first parallelogram linkage, has four sides with an equal length, and is linearly extended or retracted along a linear guide. Links of the first parallelogram linkage and links of the second parallelogram linkage are configured to rotate while being in a restrained state of 90° at pivots of both ends of the common link of the first and second parallelogram linkage, respectively. An arm is provided at a pivot of an end of a link opposed to the link of the first parallelogram linkage such that the arm rotates in a restrained state of 90° relative to the link.
