Abstract
A passage barrier has first and second guide elements that cooperate to define a gate region, through which a person passes from an entrance region into a passage region. The passage barrier has a drive drive unit. The drive has an output unit including a hollow shaft having an outer shell surface. The hollow shaft has a barrier element mount formed for fixing a plate-shaped barrier element on the hollow shaft and is formed substantially in a U-shape. The barrier element is fixed between the limbs of the barrier element mount, wherein at least two adhesive grooves are provided on the inside at the base of the barrier element mount. At least two opposing adhesive grooves are provided for receiving an adhesive on the inside on both limbs of the barrier element mount and opposing grooves are formed on the inside at distal ends of the barrier element mount.
