JOINT FOR TORQUE TRANSMISSION, AND ELECTRIC POWER STEERING DEVICE

WIPO Patent Application WO/2019/176871

A1

Provided is a structure of a joint for torque transmission, with which the occurrence of abnormal sounds can be minimized when the rotational direction of a drive shaft is reversed. An intermediate transmission member 17 has intermediate transmission teeth 21 in a plurality of circumferential locations. Each of a pair of end transmission members 18 has end transmission teeth 37 in a plurality of circumferential locations. Each of a pair of elastic members 19 has insertion holes, through which the end transmission teeth 37 are axially inserted, in a plurality of circumferential locations. The end transmission teeth 37, having been axially inserted through the insertion holes, and the intermediate transmission teeth 21 are disposed alternately in the circumferential direction with first circumferential gaps therebetween. The axially inner end parts of the end transmission teeth 37 are provided with tapered parts 40 in which the circumferential width dimension decreases toward the axially inner side, and circumferential width dimension of the axially inner end edges is smaller than circumferential gaps between both circumferential side edges of the insertion holes 30.
