<P>PROBLEM TO BE SOLVED: To provide a crushing device and a speed reduction mechanism of a simple structure capable of smoothly supplying lubricating oil splashed by gears to a plurality of bearings. <P>SOLUTION: The speed reduction mechanism has a plurality of gears 32, 33, 35, 36 supported by bearings stored in a casing 39 and transmits power from the motor to a rotary shaft at a load side. The speed reduction mechanism is provided with a rib 60 for supporting the bearing projectingly formed on both side inner wall of the casing 39, an extension part 61 forming a part of the rib 60 toward an upper edge part 39b of the casing 39, a guide member 62 arranged over a part between the extension part 61, receiving lubricating oil splashed by tooth parts of the gear 36 and guiding the same on the rib 60 along the extension part 61, an oil pocket 63 collecting lubricating oil flowing out along the rib 60 from the guide member 62, and supply routes 64, 65 formed on the rib 60 and supplying lubricating oil to the bearings from the oil pocket 63. <P>COPYRIGHT: (C)2010,JPO&INPIT |
