PURPOSE:To enable to use a flexible hose both as the confirmation of oil level and the smooth extraction of oil by a structure wherein the flexible hose is coupled at the lower end to the oil bath case, within which lubricating oil is sealed, and the tip of the hose is held at the height of oil level. CONSTITUTION:A charging hole 3 for the lubricating oil 2 is provided at the upper part of the oil bath case 1 and normally equipped with a plug 4. On the other hand, a drain hole 5 for replacement of the oil is provided at one side of the lower end of the case 1 and coupled with the flexible hose 6, at the tip of which a hooking piece 7 is provided in order to be hung on the holding piece 8 on a frame. The holding piece 8 is set at the position that the tip of the flexible hose 6 is at the height of the level of the oil 2, when the hooking piece 7 is hanged on the holding piece 8. In this way, in order to discharge the oil 2, a plug 9 is removed and the flexible hose 6 is directed downward. Furthermore, in order to confirm the height of the level of the oil 2, the only thing to do is to remove the plug 9 and to fill the oil up to the tip of the flexible hose 6 while holding the hose 6 at its set position. |
