ABSTRACT:
A mouse body includes a housing having a bottom wall formed with an opening which is surrounded by a recess in the bottom wall. An outer annular disk is fitted in the recess and adhesively bonded to the bottom wall of the mouse body. The annular disk has an inner peripheral surface that surrounds a circular aperture in the annular disk and connects an inner main surface of the annular disk to an outer main surface of the annular disk. An inner split lock ring has a relaxed state, in which the lock ring is larger than the aperture in the annular disk, and a compressed state, in which the lock ring can be placed in the aperture. When the lock ring is in the aperture, it can be released to an intermediate state, in which an outer surface of the lock ring engages the annular disk at the periphery of the circular aperture.
