A one-way braking hinge capable of self-aligning a shaft and a one-way clutch is provided. The one-way braking hinge () includes a first leaf (), a shaft () rotatably supported by the first leaf (), at least one resistance part () that resists rotation of the shaft (), a second leaf () rotatably coupled to the shaft (), a one-way clutch () into which the shaft () is inserted, and a position adjusting member () to which the one-way clutch () is fixed. The position adjusting member () is position-adjustably coupled to the second leaf ().

One-way damping hinge

A movable memberis connected to a first hinge membersuch that the movable memberis unable to turn but able to move in the axial direction. A hammer memberis non-turnably connected to a second hinge memberThe movable memberis caused to abutted against the hammer memberby a coiled spring (not shown). A force conversion mechanism (not shown) is disposed between contact surfaces of the movable memberand hammer memberand adapted to convert a biasing force of the coiled spring to a force for turning the hammer memberAn abutment projectionis formed on an outer periphery of the second hinge memberAn abutment recessinto which the abutment projectionis fitted is formed in an outer periphery of the hammer memberA widthof the abutment recessis set slightly larger than a width Wof the abutment projectionso that the hammer membercan be turned relative to the second hinge memberto that extent.
