A window shade motor includes improved apparatus for securing a spring to a body element of the motor. The body element has a recess and the spring includes a bent portion near its end. The bent portion extends into and engages the edges of the recess in order to secure the spring against rotation with respect to the body. The end of the spring beyond the bent portion is positioned to engage the shade roller to maintain the bent portion of the spring within the recess. |
