The shade 81 has an inclined surface 86b. The inclined surface 86 b is provided between the flat surface portion 86 a and the outer edge portion 82. It is preferable that the angle formed by the flat portion 86a and the inclined surface 86b is an obtuse angle or a right angle. The shade 81 has end caps 84 at both ends in the longitudinal direction. The end cap 84 has wall portions 84 b that cover openings at both ends in the longitudinal direction of the shade 81. The end cap 84 is made of the same material as the shade 81. The end cap 84 has a protruding portion 84 a that protrudes in a hook shape in a direction substantially orthogonal to both longitudinal end surfaces of the shade 81. The end cap 84 is joined to both ends of the shade 81 in the longitudinal direction by an adhesive or heat welding, but the joining method is not limited thereto. The protruding portion 84a is substantially orthogonal to the wall portion 84b. The protruding portion 84a faces the upper surface portion 22a of the main unit 21 with a gap in the state where the lamp unit 41 is attached to the main unit 21.

  The shape of the shade is not limited to the shape of the present embodiment. For example, the cross-sectional shape of the shade can be formed into a semicircular cross-section, a square cross-section, and a trapezoidal cross-section. The means for attaching the shade 81 to the lamp base 42 is not limited to the one using the screw 63. For example, a claw is provided at a position corresponding to the protruding portion 83 of the shade 81, and the claw is formed in the hole formed in the lamp base 42. The structure engaged with may be sufficient. Further, as shown in FIG. 9, the end cap 84 is configured to be attached to both ends in the longitudinal direction of the body portion of the shade 81 when the shade 81 is assembled, but may be integrally formed with the body of the shade 81. The end cap 84 can be made of the same material as that of the shade 81 to obtain a sense of unity with the appearance of the shade 81. However, the end cap 84 can be formed of a different material or colored with a different color from the shade 81. Can easily create variations in appearance design.

  The spring portion 90 is disposed at one end in the longitudinal direction on the mounting surface side of the lamp unit 41 and is mainly composed of a spring member 35 and a spring support portion 36 that supports the spring member 35.
