PROBLEM TO BE SOLVED: To provide a handling device of which a structure can be simplified and which has both of an illumination function and a drip-proof function.SOLUTION: A handling device includes: a circuit board 50 to which a light-emitting element 53 is attached; a rotary electronic component 100 which is attached onto the circuit board 50; cases 10, 30 which store the circuit board 50 and the rotary electronic component 100; and a cover 210 which is so mounted as to cover a front face M1 of the cases 10, 30. Between the cases 10, 30 and the cover 210, a light guide 170, which has a light guide body 171 for preventing drip of liquid immersed from the cover 210 side from reaching the front face M1 of the cases 10, 30, is located. An illumination part 173 for illuminating a light display 213 of the cover 210 is projected from one face of the light guide body 171, and a light introduction part 175, which is inserted into the upper and lower cases 10, 30 and introduces a light from the light-emitting element 53 thereinto, is projected from the other face.SELECTED DRAWING: Figure 4 |
