PROBLEM TO BE SOLVED: To provide fittings having a function assisting the open-close operation of a door body by a linear movement going with the rotary operation of the door body. SOLUTION: The fittings have the door body rotatable to a frame body and a movement member linearly moved to one of the frame body and the door body while being interlocked with the rotation of the door body. The fittings further have a connecting member with one end section rotatably connected to the movement member and the other end section rotatably connected to the other in the frame body and the door body. The fittings further have an external-force working device being fitted to one of the frame body and the door body, having an engaging member engaged with the movement member when the movement member reaches a first place and working an external force to the movement member through the engaging member during a time when the movement member is moved from the first place to a second place.
