  Then, when installing the lighting device 10, a pair of electric wires for feeding is inserted into the insertion holes 62 of the pair of terminal portions 33 and electrically connected to the electric wire connection portions 53 of the terminals 31, respectively.

  Further, when the lamp device 11 is mounted on the lighting device 10, the protruding portion 17 is inserted into the insertion port 37 of the socket 22, and the pair of electrode pins 19 are inserted into the insertion hole portions 42 of the pair of connection holes 41 of the socket 22. The lamp device 11 is rotated in a predetermined mounting direction. As a result, the pin portion 19a of the electrode pin 19 moves into the engagement hole portion 43 of the connection hole 41, and the large diameter portion 19b of the electrode pin 19 moves onto the engagement hole portion 43. The large portion 19b is electrically connected to the contact portion 55 of the terminal 31. Further, the key groove 18 of the protrusion 17 is hooked on the key 50 of the socket 22, so that the lamp device 11 is mounted on the socket 22.

  When power is supplied to the socket 22 through the electric wire, power is supplied from the electrode pin 19 of the lamp device 11 to the power supply circuit 16 through the terminal 31, the light emitting unit 13 emits light, and the light from the light emitting unit 13 is reflected by the reflector. It irradiates downward from 23 opening 23a.

  In this embodiment, since the terminal 31 is pressed to the outside of the insertion hole portion 42 of the connection hole 41 by the pressing portion 71, the movement of the terminal 31 in the terminal cover 32 is restricted, and the terminal 31 is inserted into the insertion hole. Protruding on the part 42 is prevented.

  Therefore, when the pair of electrode pins 19 is inserted into the insertion hole portions 42 of the pair of connection holes 41 of the socket 22 respectively, the pitch between the pair of electrode pins 19 is the widest in the size range defined by the standard. Even when the electrode pin 19 is inserted into the insertion hole 42 in a state where the lamp device 11 is offset toward the one connection hole 41 of the socket 22, the insertion pin 42 does not get caught by the terminal 31. It is possible to insert up to a predetermined insertion position.

  Further, after the pair of electrode pins 19 are inserted into the insertion hole portions 42 of the pair of connection holes 41, respectively, when the lamp device 11 is rotated in a predetermined mounting direction, the insertion hole portion 42 is placed on the engagement hole portion 43. The peripheral surface of the large-diameter portion 19b of the moving electrode pin 19 abuts on the introduction surface portion 57 of the abutting portion 55 of the terminal 31, and the abutting portion 55 is pushed by the large-diameter portion 19b of the electrode pin 19. The moved contact portion 55 is elastically deformed to the outside of the engagement hole portion 43 so that the large diameter portion 19b of the electrode pin 19 gets over the top portion 56 of the contact portion 55 and gets over the top portion 56 of the contact portion 55. The connection surface portion 58 of the contact portion 55 is in pressure contact with and electrically connected to the large diameter portion 19b of the electrode pin 19. Further, the connecting surface portion 58 of the contact portion 55 is pressed against the large-diameter portion 19b of the electrode pin 19 to urge the lamp device 11 to rotate in the mounting direction with respect to the socket 22, and the lamp device 11 is connected to the socket 22 Hold on.

However, when the lamp device 11 rotates with respect to the socket 22 in an eccentric state, the contact is pushed by the large-diameter portion 19b of the electrode pin 19. Since the portion 55 is deformed to the outside of the engagement hole portion 43 more than usual, there is a possibility that the terminal 31 is sag and the pressure contact force with the electrode pin 19 is reduced.

  In the present embodiment, when the contact portion 55 pushed by the large-diameter portion 19b of the electrode pin 19 tends to be deformed to the outside of the engagement hole portion 43 more than usual, the contact portion 55 becomes the restriction portion 72. , The deformation of the contact portion 55 is restricted, and the deterioration of the terminal 31 is suppressed.
