A modular submersible repairing system includes a working unit having a tool module capable of repairing structures in a reactor. A scanning/pitching module is capable of being selectively connected to or disconnected from the tool module, and is provided with a scanning/pitching shaft for scanning or pitching the tool module. A submersible fan module is capable of being selectively connected to or disconnected from the scanning/pitching module. A first buoyant module keeps an orientation of the tool module. A base unit includes a manipulator module internally provided with an actuator driving mechanism. An adsorbing module is capable of being detachably mounted on the manipulator module and a wall. A second buoyant module keeps the orientation of the manipulator module. The scanning/pitching module and the manipulator module are provided with a submersible connecting device capable of being operated in water for engagement and disengagement.

An oil level gauge guide device is coupled to an engine to make the operation of inserting an oil level gauge easier. The oil level gauge guide device has a guide body and a fastening portion. The guide body is generally funnel shaped and narrows gradually from a first open end toward a second open end. The fastening portion fastens the guide body to a cylinder head of main engine body in such a manner that the second open end of the guide body faces an oil level gauge insertion opening of the cylinder head into which the oil level gauge to be inserted.

A plurality of bowden cables extend between a pivotal mirror unit and a control device so that the mirror unit is pivotally movable in response to manipulation of the control device. A spring-biased wire guide member engages the bowden cables in a manner to constantly apply the same with substantially equal tensions to achieve assured remote control.
