<p><P>PROBLEM TO BE SOLVED: To provide a noise reducing device for transmission which can apply a constant agitating resistance to a reverse gear without relying on lubricating oil consistency by generating a rotating resistance only at low-speed rotation causing tooth striking sound generation or at low lubricating oil consistency. <P>SOLUTION: The noise reducing device for transmission, which suppresses the tooth striking sound, coaxially supports a counter shaft 4 within a transmission case 6, and applies an agitating resistance of lubricating oil 28 to the reverse counter gear 20 by providing the reverse counter gear 20 constantly driven and rotated by power from an input shaft 2 in the counter shaft 4 so as to be soaked in the lubricating oil 28 within the transmission case 6 so that a tooth flank of the reverse counter gear 20 is pushed to a tooth flank of reverse idle gear 16 geared with the reverse counter gear 20 by the applied agitating resistance, wherein a blade 27, which agitates the lubricating oil 28 and transforms elastically based on the agitating resistance applied from the lubricating oil 28, is provided in a side surface 26 of the reverse counter gear 20. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
