To simultaneously carry a plurality of articles to be carried, and avoid the influence of the foreign matter of the mutual articles to be carried by forming a driven arm shorter than a prime mover arm, and composing a carrying device by three shaft operating elements of going in/out action, linear vertical action and tilting rotational action.
In a link arm mechanism, the base end of a prime mover arm 5a is pivotally mounted on a link arm main body 11, and a driven arm 5b is engagingly mounted on the tip of the prime mover arm 5a. The prime mover arm 5a is formed longer, and the driven arm 5b is formed shorter, contracted and extended by being acted in concert with the prime move arm 5a. A carrying device main body 3 is travelled in a travelling action direction V1 on a track 4. Handling operation functional elements mounted on a main body 3 hold and carry an article to be carried 1 by mutually combining three shaft action in a direction V5 for going in/out action for vertically folding up, a direction V3 for linear vertical action and a direction for tilting rotational action to change the attitude of the angle of the article to be carried in addition to a direction V2 for holding the article to be carried. Therefore, a plurality of articles can be simultaneously carried, and carrying form that avoids the influence of a foreign matter can be set up.
