A transfer arm is formed of a first short link, a first parallel link pivotally connected to the first short link, a second short link pivotally connected to the other ends of the first parallel link, a second parallel link pivotally connected to the second short link, and a third short link pivotally connected to the second parallel link. A linear guide is integrally formed with the first short element to extend in a direction perpendicular to the first short link. One link element of the second parallel link extends and is linearly slidably attached to the linear guide. A holding plate is connected to the third short link to be moved linearly according to a rotation of a drive shaft connected to the first parallel link while deforming parallelograms formed by the first and second parallel lines. |
