PROBLEM TO BE SOLVED: To provide a power transmitting shaft unit capable of suppressing torque fluctuation.SOLUTION: A power transmitting shaft unit U includes a first shaft 14, an intermediate member 15 eccentric in a first direction X1 with respect to the first shaft 14, and a second shaft 16 eccentric in a second direction X2 with respect to the intermediate member 15. It further includes a first connecting element 29 connecting the first shaft 14 and intermediate member 15 so that they can transmit a torque while allowing a relative movement toward the first direction X1 and a second connecting element 30 connecting the intermediate member 15 and second shaft 16 so that they can transmit a torque while allowing a relative movement toward the second direction X2, wherein the first direction X1 and second direction X2 are identical or opposite directions mutually. Connecting projections 32 and 34 of respective connecting elements 29 and 30 engage with corresponding connecting grooves 31 and 33, and torque transmitting sections are formed at locations offset in a direction opposite to the first direction RX1 and a direction opposite to the second direction. |
