<p>PROBLEM TO BE SOLVED: To provide a keyboard device which is capable of protecting parts and maintaining key touch operation stable for a long period of time by suppressing the outflow of a lubricant. SOLUTION: A partition wall part 35 is extended upward from the front of a bas part 39, extends approximately perpendicularly with a slight backward inclination and partitions a pivotal supporting part E side where a turning shaft part 33 exists and a rear region side where a switch substrate 23, etc., exist, thereby shutting off the backward splashing and outflow of the lubricant backward from the pivotal supporting part E. A floor part 36 extends forward from the middle part of the partition wall part 35 and a top surface 36a inclines slightly upward toward the front. The segment of a dog leg shape formed by a partition wall part front 35a and a floor part top surface 36a functions as a stagnation part for the lubricant splashed and discharged from the pivotal supporting part E, by which the splashing and outflow are additionally suppressed.</p> |
