It is an object of the present invention to provide an organometallic complex that can emit phosphorescence. A bleed wrench coaxially slides along the tool to engage the bleed fitting. In the evaporating dish cleaning mode, a cleaning liquid made of citric acid solution is pumped into an evaporating dish 35, it is heated to a predetermined temperature, and it is left therein. A porous anode is mounted on the other surface of the electrolytic film, which faces the outside of the casing member, and connected to the anode of the power supply. The energy-absorbing device is configured to transmit load received from the impact directly to the edge surface of the vehicle rail through the second crush surface.
