Abstract
In a drive force transmission device, a shock-absorbable rubber is placed between a driving-side rotatable body and a driven-side rotatable body. A bridge portion is placed at a deep side of a holding recess of the shock-absorbable rubber and connects between a primary damper portion and a secondary damper portion. At least one cut part penetrates through the bridge portion in an axial direction of the shock-absorbable body and extends in a radial direction of the shock-absorbable body.
