According to the present invention, as described above, intermediate bar remains the abutting region of the reality of cam returning spring.Similar arc component is left a blank out butting section in this region.But alternatively can also expect and arrange, the transverse section via component provides butting section individually.
For the contact of the low friction of leg on the material of intermediate bar of cam returning spring, in component, protrude from the lateral end of the crossbeam of intermediate bar the hook-shaped lug boss single type outwards arched upward.Wide or at least similarly the shape of involute shape can be there is in the contact areas wide.Lug boss hook-shaped if desired can also exist as the component engaged with intermediate bar independently, thus the matrix of intermediate bar can also be made more simply.
Can exist as at least one roller or slip surface at the supporting surface of the first end side tip or the intermediate bar near it or thrust surface.Same situation is also applicable to the corresponding running face of cam.When slip surface, this slip surface can by these lid of side plate towards the side cross-over connection of cam.When the Structure deformation for the corresponding running face of supporting surface, thrust surface or cam, corresponding roller operates on the axle of cross-over connection side plate via rolling bearing or sliding bearing.
The fastening suitable measures of component on intermediate bar of approximate arcuate is the theme of other dependent claims.Therefore it is suggested that, the cross bar of component is fixedly placed between the free terminal of the internal surface of hook-shaped lug boss and an extending portion of side plate.
According to another dependent claims, side plate is connected to each other via the camber member of sclerosis on the first end side tip, wherein, can also expect multiple camber member.Camber member can start from intermediate bar single type.But can also expect that this camber member is as independent component.Extend arc piece from each side plate if desired, these arc piece is then connected to each other in the region of their sensing end each other.
