Abstract
Official abstract text for this publication.
A clutch device is provided which facilitates an operation of checking whether or not spring seats have been properly disposed and effectively prevents falling off or a change in attitude of the spring seats, thereby reducing the labor required for manufacture. A clutch device 100 includes a pressure plate 110 which presses friction plates 103 which are rotationally driven by a drive shaft against clutch plates 107 . The pressure plate 110 includes clutch springs 112 and spring seats 113 disposed in receiving portions 111 having a concave shape. Each spring seat 113 has two plate-shaped arms 113 a and 113 b extending along the bottom 111 a of the receiving portion 111 and has a C-like shape. Protrusions 114 a and 114 b project from the peripheries of the arms 113 a and 113 b . Recesses 111 b into which the protrusions 114 a and 114 b fit are formed in an inner wall portion of each receiving portion 111 at a position near the bottom 111 a of the receiving portion 111.
First claim
Opening claim text (preview).
The invention claimed is: 1. A clutch device which transfers rotational drive force from a drive shaft to a driven shaft and interrupts the transfer, comprising: a clutch hub which is coupled with the driven shaft and holds a clutch plate which faces a friction plate rotationally driven by the drive shaft; a pressure plate which has a concave receiving portion and which can move toward and away from the clutch hub and which presses the friction plate or the clutch plate; an el…
