Abstract
A watertight key unit includes a key and an elastic sealing part. The key is mounted on a key-mounting wall, extends through a key-inserting hole in the key-mounting wall, and has a peripheral wall. The sealing part extends from a lower end of the peripheral wall of the key, has a peripheral wall that surrounds the peripheral wall of the key, and cooperates with the peripheral wall of the key to define a spacing groove therebetween. The peripheral wall of the sealing part is surrounded by and abuts elastically and sealingly against a hole-defining wall of the key-inserting hole.
