<p>PURPOSE:To improve the workability and economy by forming a hole at the outer bottom of a bearing box, forming a communication hole communicating between the hole and the interior of a casing in the box, and leading the leads of a temperature sensor from the communication hole externally, thereby simplifying the leading structure of the lead of the sensor. CONSTITUTION:A hole 21 is formed at the outer bottom directly under a bearing box 2, and enclosed by a sealing member 22. A communication hole 23 is formed at the box 2 to communicate between the hole 21 and the interior of a casing 1, and leads 9a of a temperature sensor 9 are externally lead through the hole 23 and the member 22. Accordingly, since the leads 9a of the sensor 9 can be led externally directly under the box 2 disposed with the sensor 9, the drawing structure can be simplified.</p> |
