Abstract: A drive device protection structure has a rotary electric machine, a gearbox connected the rotary electric machine, an undercover disposed underneath the drive device and a protecting plate provided to the undercover. The rotary electric machine has a rotary electric machine housing that has a rotary electric machine flange. The gearbox has a gearbox housing that has a gearbox flange. The rotary electric machine flange and the gearbox flange are connected together. The rotary electric machine flange and the gearbox flange are formed such that a lower surface of the gearbox flange is positioned lower than a lower surface of the rotary electric machine flange. The protecting plate is formed of a material more rigid than a material of the undercover. The protecting plate is provided beneath connecting part between the rotary electric machine flange and the gearbox flange so as to face the connecting part.

Abstract: An apparatus for electrically operating a circuit breaker arranged such that the change-over lever movable between an electrical operation mode position and a manual operation mode position has provided therewith a blocking portion which, while allowing the operation of the manual operation handle when the change-over lever is in the manual operation mode position, engages the manual operation handle to prevent the operation of the manual operation handle when the change-over lever is at the electrical operation mode position. Therefore, the operation of the manual operation handle in the electrical operation mode can be ensured to be prevented, avoiding the damages to the electrical operating apparatus, thsu enabling to provide a highly reliable apparatus for electrically operating a circuit breaker.
