The present invention relates to a tongue depressor with a light. Thus, when the rotational speed of the vehicle is lowered until the motor gets the lock state while the vehicle is driven in the state where the accelerator is opened with the opening degree being equal to or more than the judgment opening degree, the drive current is decreased whereby a temperature of armature coils is prevented from abnormally rising. The clip further includes a hinge connecting the first and second side, the hinge being disposed on the top of the clip. A fill passage is connected to a portion of the supply passage, the portion being located between the electromagnetic pressure regulating valve and the electromagnetic on-off valve. The connecting surfaces includes a first side surface, a second side surfaces and a third side surface between the first side surface and a second side surface, A first included angle of the first incident surface and the first diffusion surface is equal to or greater than about 90 degree. The rare-earth fluorescent complex is characterized by having a cyclic ligand comprising a 4-biphenyl-2,2\u2032:6\u2032,2\u2033-terpyridine skeleton and a 2,6-bispyrazine skeleton bonded thereto.
