Provided are an organic electroluminescence device having high luminous efficiency and a long emission lifetime, and a transition metal complex compound realizing the organic electroluminescence device. In the transition metal complex compound, three ligands are crosslinked with a crosslinking group having a saturated cyclic structure or a saturated polycyclic structure in a tripod manner. The organic electroluminescence device includes an organic thin film layer composed of one or multiple layers including at least a light emitting layer, the organic thin film layer being interposed between a pair of electrodes. In the organic electroluminescence device, at least one layer of the organic thin film layer contains the transition metal complex compound.

A refrigerator includes a thermally insulated housing opening forwardly at a front surface thereof; a door for selectively opening and closing the opening of the housing; a magnetic gasket fitted to a portion of the door which is engageable with an open edge of the housing; a pivotally supported handle connected to the door for movement between opened and closed positions for opening and closing the door, respectively; and a trigger member drivingly coupled with the handle for movement between projected and retracted positions. The trigger member is moved from the retracted position towards the projected position, as the handle is pivoted from the closed position towards the opened position, to abut the open edge to thereby physically release a contact between the magnetic gasket and the open edge. The trigger member is spaced a distance from an abutment face of the open edge of the housing so long as the handle is held in the closed position, but temporarily brought into engagement with the abutment face of the housing as the handle is pivoted from the closed position towards the opened position to open the door.
