Abstract

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.

First claim

What is claimed is:

1 . A vibration damping device comprising:
a vibration-damping device main unit including a fixture member; and a bracket having a mounting space, the vibration-damping device main unit being inserted into the mounting space of the bracket from a lateral side such that the fixture member of the vibration-damping device main unit is arranged between opposed inside faces of the mounting space and securely supported by the bracket, wherein the bracket includes engaging pieces on the respective opposed inside faces of the mounting space while the vibration-damping device main unit includes detent engaging faces formed on the fixture member, and engaging action of the engaging pieces with respect to the respective detent engaging faces prevents the vibration-damping device main unit from becoming dislodged from the mounting space of the bracket, and opposed walls of the mounting space of the bracket 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 being parallel to each other.

2 . The vibration damping device according to claim 1 , wherein a gap is provided between overlapped surfaces of an inside surface of each engaging piece and the fixture member.

3 . The vibration damping device according to claim 1 , wherein the inspection flat surface provided to the external side surface of the bracket is provided adjacently to the aperture window in a direction of parting a mold for molding the external side surface of the bracket.

4 . A method of manufacturing the vibration damping device according to claim 1 , comprising
a non-destructive inspection step of measuring relative positions of the inspection flat surface provided to the outside surface of each engaging piece and the inspection flat surface provided to the corresponding external side surface of the bracket such that engagement failure between the engaging piece and the corresponding detent engaging face is detected.

5 . The method according to claim 4 , wherein the relative positions of the inspection flat surfaces are measured in a direction orthogonal to the inspection flat surfaces.
