The main body 31A has a convex portion 35 formed in an annular shape along the outer circumference on the outer peripheral portion on one end side by a predetermined length from the end on the side where the male terminals 33a and 33b of the main body 31A are formed. .. Similar to the above, the predetermined length is such that the male terminals 15a and 15b and the female terminals 25a and 25b of the connecting member 1B are electrically connected. The main body portion 31A is inserted into the other end side of the connecting member 1B, and the convex portion 35 is fixed by fitting with the concave portion 18b.

Although the convex portion 26 and the convex portion 35 are formed in one annular shape, they may be divided into a plurality of portions. That is, the convex portions may be randomly arranged on the outer circumference forming the annulus. This is because the recesses 18a and 18b are formed as one annular groove, and can be fixed if they can be fitted with any part of the recesses.

Further, in FIG. 10 and the like, a fitting method using a protrusion and a groove is used for both the connection between the connecting member 1B and the LED lighting device 2B and the connection between the connecting member 1B and the electronic device 3A, but only one of them is used. The method may be used, and the other method may be another method shown in the first embodiment, the second embodiment, or the like.

According to the present embodiment, a concave portion 18a as a groove portion is formed at the end portion, and the concave portion 18a as a protrusion formed at the other end portion 23B of the LED lighting device 2B is fitted and fixed. By doing so, for example, the other end 23B of the LED lighting device 2B is joined by fitting the convex portion 26 which is a protrusion and the concave portion 18a which is a groove portion, so that the LED is attached to the connecting member like a cap of a writing instrument, for example. The joined state can be achieved by simply pushing in the lighting device 2B.
