Therefore, the housing 10 is pushed away from the attachment device 5, the upper surface of the first engagement protrusion 24 contacts the upper wall of the engagement hole 57, and the upper surface of the second engagement protrusion 34 is the engagement hole 58. It is held at a position in contact with the upper wall. Thereby, it is prevented that the lighting fixture 1 rattles in the mounting direction, that is, the direction in which the distance from the mounting fixture 5 changes.

  When the outer diameters of the four protrusions 84 are set to a value that is slightly smaller than the inner diameter of the round hole 37, the protrusions 84 are formed on the upper and lower sides of the casing 10 in the same manner as the protrusions 61 to 64. It also acts as a position defining member that defines the position in the left-right direction.

  Further, when the lighting fixture 1 is attached to the mounting fixture 5 in the correct orientation, the power receiving terminals 17 and 19 formed on the bottom surface 11 of the housing 10 come into contact with the drive current feeding terminals 87 and 89 of the mounting fixture 5 respectively. Similarly, the power receiving terminals 18 and 20 formed on the bottom surface 11 come into contact with the signal current power supply terminals 88 and 90 of the fixture 5, respectively, so that power can be supplied from the fixture 5 to the lighting fixture 1. As described above, since the power feeding terminals 87, 88, 89 and 90 are respectively biased outward, the contact with the power receiving terminals 17, 18, 19 and 20 is ensured.
