To provide a gate openable/closable both inward and outward, which enables a wheelchair user etc. to go into/out of the gate by pushing open a door body.

A gatepost 1 is formed in such a shape as to have a front and a back different in width from each other, that is, to have the narrow front and the wide back; side surfaces on both the width-direction sides of the gatepost 1 are formed in such a trapezoidal shape as to be equiangularly expanded and inclined and to be set symmetrical in a width direction; and the door body 2 is suspended and supported on the gatepost 1 via a hinge 3 using an adjusting fitting 3a on the backside of the gatepost 1 and a hinge fitting 3b of a hanging-side stile 21 of the door body 2. The axial center of the hinge 3 and the inward and outward center line of the hanging-side stile 21 are colinearly positioned, and the hinge 3 is covered with a back cover 4 of the gatepost 1 and an end cover 5 of the end stile 21. A space for opening the door body 2 to the outside is formed on the expanded and inclined side surface of the door body 2, and inside opening/closing angles are regulated by the back cover 4. Thus, the door body 2 can be pushed open and opened/closed both inward and outward by setting the opening/closing angles in the range of 95-120, and the wheelchair user etc. can go into/out of the gate A only by pushing the door body 2.
