A speed reduction device including a first internally meshing planetary gear mechanism and a second internally meshing planetary gear mechanism, including: a housing; an input shaft rotatably supported by the housing at its first shaft portion through a first bearing; a planetary gear member rotatably supported by an eccentric shaft portion of the input shaft through a second bearing; and an output shaft rotatably supported by a second shaft portion of the input shaft through a third bearing, wherein a distance in an axial direction between a first support position and a second support position is equal to a distance in the axial direction between the second support position and a third support position, and a distance in the axial direction between the second support position and an input-side meshing position is equal to a distance in the axial direction between the second support position and an output-side meshing position.

An electrically heated catalyst device includes a catalyst support, a surface electrode disposed on an outer surface of the catalyst support and extending in an axis direction of the catalyst support, a wiring line member including a root section extending in the axis direction of the catalyst support and comb teeth-like wiring lines extending from the root section in a circumference direction of the catalyst support and fixed to the surface electrode, an outer cylinder covering an outer surface of the catalyst support, and a holding member holding the catalyst support and packed between the catalyst support and the outer cylinder, in which the catalyst support is heated by feeding a current through the surface electrode and the wiring line member. A slit extending from an outer edge in the circumferential direction of the catalyst support is formed in the root section of the wiring line member.

Electrically heated catalyst device and its manufacturing method

A suspension apparatus for an automotive vehicle employs, as its main element, a main suspension member. The main suspension memberincludes a main portionconstituted by a pipe; two body-side attachment portionsthat are fixed to opposite ends of the main portion, respectively; and a wheel-side attachment portionthat is fixed to a rear-side portion of the main portion. The opposite ends of the pipe constituting the main portionare located near to each other, such that the main portionhas a generally C-shaped configuration in its side view. The body-side attachment portionsare attached to a body of the vehicle such that those portionsare pivotable about their pivotal axes. The pivotal axes of the two body-side attachment portionsare offset from each other in a direction perpendicular to those axes, or are inclined relative to each other. Otherwise, those pivotal axes are offset from each other in the direction perpendicular thereto, and simultaneously are inclined relative to each other. The wheel-side attachment portionis attached to a wheel-holding member, not shown, that holds a wheelsuch that the wheelis rotatable. Thus, the main suspension membercan function as both a suspension spring and a suspension link.
