Abstract: A metal bracket that supports a plurality of lamp units is configured so as to be housed in the lamp chamber and to be tiltably supported by a lamp body. In this situation, a portion of the lamp body is configured so as to be a heat sink. The heat sink and the metal bracket are connected to each other by a flexible heat pipe. With this arrangement, the heat that is generated by light emitting elements included in lamp units is allowed to move to the heat sink via the metal bracket and the flexible heat pipe, and is thereby released into the space that is outside the lamp chamber. Further, due to the transformation of the flexible heat pipe having flexibility, even when the metal bracket is tilted, it is possible to easily maintain the water-proof function of the lamp without hindering the movement of the metal bracket.

Abstract: In energy absorbing structures in an entire train, a compression amount at an interface between cars at an end portion of a train is reduced and compression at an interface between cars at a center portion of the train is facilitated. In the structure, a plurality of cars (A1 to A12) are coupled to one another through couplers (B1 to B11), and energy absorbing structures (S12 to S42, S82 to S122) are provided between cars. An average compressive load corresponding to a value obtained by dividing an energy absorption amount of the energy absorbing structure by a maximum compression amount of the energy absorbing structures (S12 to S42, S82 to S122) is set smaller at an interface between cars at a center portion of the train than at an interface between cars on an outer side of the train (closer to an end portion).

Abstract: A plurality of lighting units using light emitting diodes as light sources is accommodated in a lamp housing in such a state as to be supported on a common metallic support member provided tiltably. When a part or all of the lighting units are turned on, the light emitting diodes generate heat with a light emission. These light emitting diodes are supported on the common metallic support member. Also in the case in which any of the lighting units is turned on, therefore, the heat generated by the light emitting diodes is moved to the metallic support member having a large heat capacity through boards and light source support blocks by a heat conducting function. Consequently, a rise in the temperatures of the light emitting diodes can be suppressed.
