Abstract: Provided is a vibration isolation device such that weight reduction can be achieved and it is possible to simplify the structure of a resin molding die for molding the bracket member. Engagement in a direction where the external member (60) slips out of the bracket member (30) occurs in a structure achieved in such a way that a pair of first wall section parts (62) of the external member (60) are installed inside the bracket member (30). As a result, it is possible to curb a situation where, as in the case of conventional vibration damping devices, undercut shapes are formed. Consequently, it is possible to simplify the structure of the resin molding die for molding the bracket member (30). Furthermore, as regards the external member (60), a portion between the leg sections (50), which form a pair, is omitted, and therefore, weight can be reduced correspondingly.

Abstract: A leaf seal has a pair of annular packs of stacked leaves. Each pack is mountable to one of the components with its leaves extending towards the other component such that the leaf edges of at least one of the packs are presented for wiping contact with the other component. The packs are axially spaced from each other by a controlled axial clearance.

Further, within each pack the packs are positioned such that, when viewed in the axial direction, the leaves of each pack of the pair substantially obscure the interleaf gaps of the other pack of the pair. The controlled axial clearance is the dominant flow restriction in the seal determining the amount of leakage flow through the seal.
