Title:
POWER TRANSMISSION DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP2016217373
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress occurrence of rattling sound in a planetary gear mechanism, without lowering assemblability.SOLUTION: An O ring 40 provided between a fitting hole 24b of a ring gear plate 24 and a fixing pin 38 fitted in the fitting hole 24b, when a force in a rotation direction acts also on the ring gear plate 24 by a ring gear 22r receiving the force in the rotation direction, receives a compression force between the fitting hole 24b and the fixing pin 38. Therefore, by the O ring 40 being compressively deformed, absorption of rotational variation energy of an engine 14 becomes possible. Energy absorption by compressive deformation of the O ring 40, to put it in an extreme, does not require slide resistance, and unlike the energy absorption by the slide resistance, a tension force does not need to be raised to increase an energy amount to be absorbed (that is, a large press-in load is not necessary when assembling). Therefore, occurrence of rattling sound in a planetary gear mechanism 22 can be suppressed without lowering assemblability.SELECTED DRAWING: Figure 2
