摘要： A vibration damping device including a vibration-damping device main unit attached to a bracket from a lateral side by a second attachment member being fitted to opposed walls provided on widthwise opposite sides of the bracket. The bracket includes flexible latches extending from the respective opposed walls forward in a direction of attachment. The second attachment member includes outer recesses respectively opening onto surfaces overlapped with the respective opposed walls. Each latch has a slope portion sloping inward in a width direction of the bracket such that a distal end face of the latch is inserted in the corresponding outer recess. The distal end face of the latch is latched by a forward wall inner face of the outer recess, and displacement of the second attachment member relative to the bracket in a direction of dislodgment opposite to the direction of attachment is limited.

摘要： A vibration damping device including a vibration-damping device main unit inserted into a mounting space of a bracket from a lateral side and securely supported by the bracket. The bracket includes engaging pieces on respective opposed inside faces of the mounting space, and engaging action of the engaging pieces with respect to respective detent engaging faces formed on a fixture member of the vibration-damping device main unit prevents the vibration-damping device main unit from becoming dislodged from the mounting space of the bracket. Opposed walls of the mounting space are each penetrated by an aperture window, and inspection flat surfaces are separately provided to an outside surface of each engaging piece visible from an outside through the aperture window and a corresponding external side surface of the bracket that is off the aperture window. The inspection flat surfaces are parallel to each other.

摘要： A torque rod for straddling connection target members including a rod member and a rubber bushing provided to a lengthwise end of the rod member. The rubber bushing includes an inside shaft member, an outer peripheral member to be attached to one of the connection target members, and a rubber elastic body connecting the inside shaft member and the outer peripheral member. The rubber bushing is a part separate from the rod member and the end of the rod member is fixed to the inside shaft member. The rod member includes an abutting face to abut against the one of the connection target members without interposing the outer peripheral member of the rubber bushing. A stopper to limit an amount of elastic deformation of the rubber elastic body in the rubber bushing is constituted by including the abutting face of the rod member.

摘要： A fluid-filled vibration damping device including an inner member, an outer member having a tubular part, a main rubber elastic body elastically connecting the two members, and a partition disposed on a radially inner side of the tubular part. An axial end portion of the main rubber elastic body is anchored to a radially inner surface of the tubular part and includes a sealing rubber. The partition includes a press-sealing face positioned at an outer peripheral edge of an axial end face thereof, and is pressed against an axial end face of the sealing rubber at the press-sealing face. A seal rib protruding axially outward from the press-sealing face of the partition is more strongly pressed against the axial end face of the sealing rubber such that a fluid-tight sealing is provided axially between the sealing rubber and the partition.

摘要： A fluid-filled vibration damping device including an inner member, an outer member having a tubular part whose radially inner surface has a quadrangular tube shape, a main rubber elastic body elastically connecting the two members, and a partition having a quadrangular plate shape disposed on a radially inner side of the tubular part. An outer peripheral surface of an axial end of the main rubber elastic body is anchored to the radially inner surface of the tubular part. An annular sealing rubber pressed against an outer peripheral edge of an axial end face of the partition is provided to the axial end of the main rubber elastic body. An axis-perpendicular inside dimension and a width dimension of the sealing rubber are made larger in a diagonal direction of the radially inner surface of the tubular part than in an opposite side direction thereof.

摘要： A rotor of a rotating electric machine includes a rotor core equipped with a cooling passage, a first retaining member disposed on one end side of the rotor core, and a second retaining member disposed on another end side of the rotor core. An inlet-side through hole of the first retaining member is inclined with respect to an axis of the rotor. An outlet-side through hole of the second retaining member is inclined with respect to the axis of the rotor. When the rotor is rotated, a cooling gas is introduced into the cooling passage through the inlet-side through hole, and the gas is discharged from the cooling passage through an outlet-side through hole.
