PURPOSE:To regulate optionally the opening degree of a door such as the door of a car by fitting the regulation mechanism composed of a belt having a plurality of fixing holes in the longitudinal direction and a fixing part being fastened into said holes, to the door. CONSTITUTION:The adjusting mechanism 6 regulating the stroke is furnished on the left and right door-stays in a back door 1. The adjusting mechanism 6 is composed of a belt 7 and a fixing protrusion 9. To regulate the opening degree of the back door 1, a fixing hole 8 at an optional position on the belt 7 is fitted on the fixing protrusion 9, and the maximum extending stroke of the door-stay 2 corresponding to the belt length, is preset. Therefore, when the door 1 is opened, the belt between the tip of a rod 4 and the protrusion 9 is stretched, and the opening degree of the back door 1 is kept. When the change for opening degree is necessary, the stretched part of the belt 7 is unfastned and the position of the fixing hole 8 is chosen optionally, thereby changing the opening degree of the door 1. |
