PROBLEM TO BE SOLVED: To provide a lighting dimming device that does not cause complication of structure but can secure a feeling of moderation during a dimming operation.SOLUTION: The lighting dimming device 1 includes: a first conductor 41 and a second conductor 51 conductively connected by a conduction plate 31 which moves in a specified course; and a light source 61 which supplies electricity via the first and second conductors 41 and 51. When a point where the conduction plate 31 contacts with the first conductor 41 is changed by moving the conduction plate 31, the resistance amount of an electricity supply channel leading to the light source 61 changes. In this device, the parts of the first and second conductors 41 and 51 where the conductive plate 31 slides are formed of conductive metallic plates and a least one of the first conductor 41 and the second conductor 51 has an uneven part that unevenly fitted to the conduction plate 31 to produce a moderation feeling at a sliding part where the conduction plate 31 slides. |
