To provide a wing type door capable of realizing a slow rotational stop at the last stroke end by giving rotational resistance in the process in the early stages of the opening or in the closing cycle.
The wing type door 6 opening and closing the front opening section of a suspended cabinet 8 is so constituted that both right and left ends of a door body 20 are respectively pivoted on a bearing shaft 18 provided to the cabinet 8 and that the rotational resistance force is given to the door body 20 in the process in the early stages of the opening or in the closing cycle of the door body 20, and therefore, impact force of abutting on a stopper can be reduced by braking the stopper on the way even if the door body 20 is tried to open and close rapidly.
