    • PROBLEM TO BE SOLVED: To provide a lamp capable of attaining easy manufacturing.SOLUTION: The lamp 1 is provided with a light-emitting section, a long tube 40 for housing the light-emitting section, and a pair of lids 50, 60 which are respectively installed on the both end parts in longitudinal direction of the tube 40. Then, the first lid 60 has a main part 52 formed in bottomed cylindrical shape and a sub part 53 which is formed in cylindrical shape and extended from the inside of the cylinder of the main part 52. The sub part 53 consists of a first portion 53a which has an outline dimension of the inner dimension or less of the surface orthogonal to the center axis of the tube 40 at the end part of the tube 40 and a second portion 53b having an outline dimension larger than the inner dimension of the surface orthogonal to the center axis of the tube 40 at the end part of the tube 40. It is possible that the second portion 53b is elastic deformed so that it may be smaller than the inner dimension of the tube 40, and in the state the second portion 53b is elastic deformed, it is inserted into the tube 40, and by a restoration force, pressure-contacts the inner circumference of the tube 40, thereby, the first lid 50 and the tube 40 are connected.
    • 要解决的问题:提供一种能够实现容易制造的灯。解决方案:灯1设置有发光部,用于容纳发光部的长管40,以及一对盖体50,60, 分别安装在管40的长度方向的两端部上。然后,第一盖60具有形成为圆筒形状的主体部52和形成为圆筒状的副部53, 副部分53由第一部分53a组成,第一部分53a具有在管40的端部处与管40的中心轴线正交的表面的内部尺寸或更小的外形尺寸, 第二部分53b的外形尺寸大于在管40的端部处与管40的中心轴线正交的表面的内部尺寸。可能的是,第二部分53b是弹性变形的,使得其可以更小 比在 管40的内径,并且在第二部分53b弹性变形的状态下,将其插入管40中,并且通过恢复力压力接触管40的内周,由此第一盖50 管40连接。
