Abstract
A device for adjusting the position of a drive element for automatically opening and closing a sliding door which is automatically opened upon stepping on of a mat switch by a customer who intends to enter a store and is automatically closed upon releasing of the mat switch by the customer who entered the store. The drive element of the automatically opening and closing sliding door is adjusted by merely once manually opening and closing sliding door. The drive elements such as limit switches are slidably mounted, not on the sliding door but on an endless wire such as an endless belt. Thus, adjusting the drive element so that the sliding door may stop just upon completely opening or closing of the door when mounting such an automatic sliding door can be rapidly and readily accomplished.
