PROBLEM TO BE SOLVED: To provide a vehicular steering force transmission device having high practical usability. SOLUTION: The vehicular steering force transmission device has: first shafts 18, 116, 122 and the like; a second shaft 60 disposed to be shifted by a predetermined distance from the first shafts; and a rotation transmission mechanism having (a) a protrusion 122 and the like protruding in a first shaft rotation axis direction, and (b) a groove 150 formed at an end of the second shaft, making the protrusion engaged with the groove, and transmitting the rotation of the second shaft to the first shaft while changing a difference between rotation phases of the two shafts. The protrusion is constituted of: a rotatable roller 122; an elastic body 138 held by the roller; and a low friction member 140 brought into contact with both a pair of sidewall surfaces which the groove has in a state of being energized by an elastic force of the elastic body. Such a constitution enables the protrusion to be engaged with the groove without causing backlash, and abnormal noise, vibration and the like caused by the backlash are suppressed.
