The power supply fitting 16 is held inside the lower case 12 by inserting the push terminal portion 19 into the insertion hole 14 from the inner surface of the bottom of the lower case 12 and protruding outward from the lower case 12. Moreover, the elastic force of the base piece 17 and the folded piece 18 of the push terminal part 19 in the expanding direction causes the push terminal part 1 to open.
9 is pressed and held against the inner edge of the insertion hole 14. Furthermore, the other free end surface 2 of this power supply fitting 16
0 constantly presses the power feeding parker stud 10 by the elastic force of the metal fitting 16 itself.
It is a current collecting part that collects the generated voltage from the Further, 21 is the base piece 1 of the push terminal portion 16.
7 and the folded piece 18, respectively, are lead wire through holes.

挾み込まれて固着されるものである。 When this push terminal part 19 is pressed with a finger, the push terminal 19 is pushed against the lower case 12 against the elastic force of the power supply fitting 16 itself and the pushing force of this push terminal part 19 against the inner edge of the insertion hole 14. Move inward, insert a lead wire (not shown) with the lead wire insertion hole 15 and the lead wire through hole 2 aligned, and when you release your finger, the lead wire insertion hole 15 and the lead wire through hole 21 will be inserted. The position of the lead wire is shifted and the lead wire is sandwiched and fixed.
