The light emission member includes a conductive plate and a pillar-like light guide unit. A light guide plate is attached to a first main surface of a supporting body. The light guide unit includes a first end unit connected to the light guide plate, a second end unit on an opposite side of the first end unit, and a ring form body provided in between the first end unit and the second end unit and penetrating the supporting body. The substrate has a light source facing the second end unit. The retaining member has a restraining unit restrained to the light guide unit and a retaining unit for retaining the substrate and faces a second main surface which is on the opposite side of the first main surface. A spacer is provided in between the supporting body and the retaining member and is penetrated by the light guide unit. The intermediate member is inserted in between the spacer and the retaining member, has a slit inserted in the light guide unit, and the width of the slit is smaller than an outer diameter of the ring form.SELECTED DRAWING: Figure 8

    【課題】車体からの発光部の脱落を防止することができる表示標識灯を提供する。【解決手段】本発明の一形態に係る表示標識灯は、光出射部材と、基板と、保持部材と、スペーサと、中間部材とを有する。光出射部材は、導光板と、柱状の導光部とを有する。導光板は、支持体の第1の主面に取り付けられる。導光部は、導光板に接続された第1端部と、第1端部とは反対側の第2端部と、第1端部と第2端部との間に設けられた環状体とを有し、支持体を貫通する。基板は、第2の端部に対向する光源を有する。保持部材は、導光部に係止する係止部と、基板を保持する保持部とを有し、第1の主面とは反対側の第2の主面に対向する。スペーサは支持体と保持部材との間に設けられ、導光部に貫通される。中間部材はスペーサと保持部材との間に介挿され、導光部に挿通されるスリットを有し、スリットの幅は環状体の外径よりも小さい。【選択図】図8
