PROBLEM TO BE SOLVED: To eliminate some problems found in a conventional implantation type lighting unit having a unit main body formed by resin that a structure of fixing part having a fixing spring set should be devised and its strength should be increased.SOLUTION: An implantation type lighting device 10 has a vessel 11 and a spring fitted part 18. The spring fitted part 18 includes a pair of protrusions 81 spaced apart by a specified amount in a lateral direction and extending upwardly so as to be raised from a flange 15, engaging grooves 82 formed at facing sides of upper half portions of the pair of protrusions 81 and a stopper receiver 83 positioned at the central part between the pair of protrusions 81. The lighting device 10 is entirely formed integrally by aluminum die-casting. This invention becomes an implantation type lighting unit 10 in which a configuration of the spring fitting part 18 receiving a base end part of the fixing spring can be made into a simple form, it has a superior fixing strength and an improved workability as well. |
