<P>PROBLEM TO BE SOLVED: To provide a self-luminous road stud including a light emission part, which is highly convenient with high durability or the like. <P>SOLUTION: A light emission part includes: a solar cell S; luminous bodies L; holders 43 where a luminous body support part 45 for supporting the luminous bodies L is projected and formed; and a control board 41 for controlling the light emission of the luminous bodies L. In the holder 43, a solar cell support part and a control board engaging part are formed respectively. The control board engaging part is engaged with the control board 41, the holders 43 are made to face each other and attached respectively to both ends of the control board 41, the solar cell S is supported between the solar cell support parts of the respective holders 43, and the luminous support part is made to support the luminous bodies L. When the control board 41 is deformed, since the force is transmitted through the respective holders 43 engaged respectively with both ends of the control board 41 to the solar cell S supported by them, the force is not easily transmitted and the damage and destruction of the solar cell S are suppressed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
