Abstract: PURPOSE:To improve operability of a handle mechanism by pivotally fitting an operation arm having a pin on the pedestal part of a door, pivotally fitting a working arm driven by the pin, and enabling the pushing or pulling operation of a handle to perform with same feeling. CONSTITUTION:When a closed door is opened by a pull method, an operation bar 12 of an operation arm 11 pivotally fitted 17 to a pedestal part 10 fixed to the door is pulled, and the operation arm 11 is rotationally moved in the arrow mark B direction. Then a pin 13a fixed to the operation arm presses the arm part 14b of a working arm 14, and hence the working arm 14 is rotationally moved (tilted) in the right direction. Because the pin 13a is energized by a spring 15, at separating a hand the operation arm 11 and the working arm 14 return to the initial position. At this time, although the operation bar 12 is intended to push, the arms is not rotationally moved by obstruction of a stopper cam 16. The case of a push metod is also similar to the case of a pull method, but the form of the arm part 14b of the working arm 14 must be changed. Hereby the pushing or pulling operation of the handle can be performed with same feeling.
