Abstract
A clutch-brake interlocking mechanism interlocks a brake with a clutch to prevent the brake and the clutch from being disengaged simultaneously so as to prevent a vehicle from inadvertently moving on a slope. The interlocking mechanism includes: (a) a friction clutch 10 including a drive-side member 11 and a driven-side member 12, wherein the drive-side member 11 and the driven-side member 12 are engaged when the drive-side member 11 is pressed toward the driven-side member 12; (b) a friction brake 20 including a brake member 22 (and 23) and a brake disk 21, wherein the brake member 22 and the brake disk 21 are engaged when the brake member 22 is pressed toward the brake disk 21; and (c) a coupling member 30 for pressing the drive-side member 11 and the brake member 22. The coupling member 30 is pivotable and has a structure such that when the coupling member 30 is pivoted to a first position, the drive-side member 11 is fully pressed while the brake member 22 is not pressed, when the coupling member 30 is pivoted to a second position, the drive-side member 11 is not pressed while the brake member 22 is fully pressed, and when the coupling member 30 is pivoted between the first position and the second position, both the drive-side member 11 and the brake member 22 are halfway pressed.
