1. A vibration damping device comprising:
a vibration-damping device main unit including a fixture member; and
a bracket having a pair of opposed walls and a mounting space defined by opposed inside faces of the opposed walls, 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 the opposed inside faces of the mounting space and securely supported by the bracket, wherein
the bracket includes a pair of engaging pieces on the respective opposed inside faces of the mounting space such that each engaging piece has a proximal end portion extending so as to slope inward in an opposite direction of the opposed wall, and has a distal end portion extending toward front in an insertion direction of the vibration-damping device main unit into the bracket,
the vibration-damping device main unit includes a pair of outer recesses open in an outer surface of the fixture member that are adapted to be fixed to the opposed inside faces, a pair of engaging walls are provided on a front side of the outer recesses in the insertion direction, and detent engaging faces are formed by wall inner faces of a front of the outer recesses constituted by the engaging walls,
the engaging pieces are configured to come into contact with the engaging walls when the vibration-damping device main unit is inserted into the bracket, are configured to be elastically deformed outwardly in the opposite direction so as to allow insertion of the vibration-damping device main unit into the bracket, and are configured to be elastically recovered inwardly in the opposite direction so as to be housed within the outer recesses so that 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
the opposed walls of the mounting space of the bracket are each penetrated by an aperture window open both in the inside faces and outside faces, and inspection flat surfaces are separately provided to an outside surface of the distal end portion 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 in the insertion direction.
