  According to the present embodiment, the outer peripheral portion of the substrate 38 is orthogonal to the radial direction of the substrate 38 so as to be separated from the light transmitting cover mounting portion 33 in a region facing the light transmitting cover mounting portion 33. A plurality of straight portions 43 are provided along the tangential direction, and the straight portions 43 of the substrate 38 are separated from the translucent cover mounting portion 33, so that the influence of the floating of the substrate 38 is small, and the translucent cover 17 The locking portion 50 (the claw portion 50a) can be easily locked to the light transmitting cover mounting portion 33 (the long hole 33a) of the instrument body 15, and the assembly of the light transmitting cover 17 can be improved. 17 assembly failures can be prevented.

  In addition, when the translucent cover mounting portion 33 is moved to the outer diameter side and the translucent cover mounting portion 33 and the substrate 38 are separated from each other, the lighting device 10 is enlarged, but the substrate 38 is moved to the inner diameter side. Thus, the illuminating device 10 can be prevented from being enlarged by separating the translucent cover mounting portion 33 and the substrate 38.

  In addition, by providing the straight portion 43 on the outer periphery of the substrate 38, when a plurality of substrates 38 are cut out from a single substrate material, the number of substrates 38 that can be cut out from a single substrate material is increased. Therefore, material removal can be improved and manufacturing costs can be reduced.

In addition, since the sensor unit 62 including the illuminance sensor 61 is attached to the fixture body 15, the side of the fixture body 15 where the sensor unit 62 is attached is heavy, and the lighting device 10 is likely to be tilted.
Three cushion members 58 are arranged on the upper surface of the instrument body 15, and one cushion member 58 is attached along one side of the power source cover 20 on which the sensor unit 62 is arranged, and the remaining two cushion members 58 are arranged on the power source cover 20.

As a result, it is easy to maintain the horizontal posture of the sensor unit 62 by one cushion material 58 on the sensor unit 62 side, and the reaction force against the ceiling surface by the two cushion materials 58 on the opposite side of the sensor unit 62 works strongly and balances. And the posture of the lighting device 10 can be stabilized.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
