Abstract

A unit for indicating lights (3a, 3b, 3c, 5, 6, 7) includes a cylindrical case (11). Opposite end portions (18, 19) of the case (11) are each connected with a corresponding end portion (19, 18) of a case (11) of a corresponding unit (3a, 3b, 3c, 5, 6, 7) through relative rotation of the cases. An electrical connection member (14, 140, 141, 142) extended between the opposite end portions (18, 19) of the case (11) establishes electrical connection between units (3a, 3b, 3c, 5, 6, 7) corresponding to each other. First and second ends (28, 29) of the electrical connection member (14, 140, 141, 142) are provided with first and second terminal portions (31, 31a; 32, 32a), respectively. At least one of the first and second terminal portions (31, 31a; 32, 32a) is provided at the plate member (15, 150, 151, 142) and includes a contact portion (42, 42b) capable of resiliently establishing linear or face-to-face contact with a corresponding terminal portion (31, 31a; 32, 32a) of a corresponding unit (3a, 3b, 3c, 5, 6, 7).
