摘要： A bicycle sprocket assembly has a first sprocket with a plurality of first radially protruding portions, a second sprocket with a plurality of second radially protruding portions and a sprocket support member. The second sprocket has more teeth than the first sprocket. The sprocket support member includes a plurality of sprocket mounting portions extending radially outwardly from a freewheel engaging portion. Each of the sprocket mounting portions has first and second sprocket mounting openings for fixing the first and second sprockets, respectively. The first sprocket mounting opening is circumferentially offset from the second sprocket mounting opening with respect to a center rotational axis of the sprocket assembly. The radially innermost edge of the second radially protruding portion is spaced by a radial distance that is smaller than a radial distance of the radially outermost edge of the first sprocket mounting openings with respect to the center rotational axis.

摘要： A bicycle sprocket assembly is provided with at least a first sprocket, a second sprocket and a first axial spacer. The first sprocket includes an outermost peripheral portion defining a plurality of first teeth, and an innermost peripheral portion defining an opening that is free of any freewheel engaging splines. The first sprocket is larger than any other sprocket of the bicycle sprocket assembly. The second sprocket includes an outermost peripheral portion defining a plurality of second teeth, and an innermost peripheral portion defining an opening having a plurality of freewheel engaging splines. The first axial spacer is fixed to the first and second sprockets such that the first axial spacer is disposed between the first and second sprockets without any intervening sprockets disposed between the first and second sprockets. The first axial spacer includes an innermost peripheral portion defining an opening having a plurality of freewheel engaging splines.

摘要： A bicycle sprocket apparatus comprises a sprocket mounting member, a first sprocket, and a second sprocket. The sprocket mounting member includes a hub mounting portion and a sprocket mounting portion, wherein the hub mounting portion is structured to be mounted to a rotating hub that rotates around a rotational axis. The sprocket mounting portion includes a first sprocket mounting surface that faces in a first direction and a second sprocket mounting surface that faces in an opposite second direction. The first sprocket is disposed at the first sprocket mounting surface, and the second sprocket is disposed at the second sprocket mounting surface. A fastener fastens the first sprocket to the first sprocket mounting surface, and a chain supporting structure extends from the fastener in the first direction and projects in the first direction away from a side surface of the first sprocket that faces in the first direction.

摘要： A foam filler is provided with a base for forming a foam and placed inside a hollow structure having a through hole. An opening having an area larger than the opening of the through hole is created in the base and surrounding the through hole. The foam filler is provided with an upper wall which follows the flow and the thermal expansion of the base at the time of heating. The upper wall closes at least part of the opening of the through hole when following the flow and the thermal expansion of the base, and thus prevents the base from entering into the through hole. The upper wall is provided in a peripheral portion of the opening and placed in a part of an area surrounding the through hole.
