Abstract
A click-stop gear shift with a detent spring in a housing. The detent spring has a projection which engages notches defined in a rotary member connected to a rotary handle. The detent spring has an outer and an inner spring portions which, together with an arcuate portion, form a curved shape. The inner spring portion is supported by a support member. By selectively positioning the support member along the inner spring portion, the stiffness of the detent spring can be changed. The ability of the relatively long spring portion to vibrate allows a desirable noise to be produced that serves as an acoustic confirmation of the gear shifting movement for the user.
