Abstract
A load adjustment apparatus for an internal combustion engine has a torsion spring (4) which is attached in a positively locking manner to a control shaft (3) for a throttle valve and a supporting part (2). At one end, the torsion spring (4) is bent in a U-shape in order to engage around a pin (17) of the supporting part (2), and has a spring tongue (16) which points in the direction of the base of the U. For mounting, the open end of the U of the torsion spring (4) is pressed over the pin (17) until the spring tongue (16) snaps in behind the pin (17). The torsion spring (4) is then connected in a positively locking manner to the pin (17) and can transmit forces in both rotation directions to the control shaft (3).
