Abstract

An attachment for a synthetic resinous reservoir as used in an automotive power steering system is provided with a steel bracket having a vertically extending dovetail slot whose horizontal width is narrowed as the height of the same decreases. The synthetic resinous reservoir has protruded from its side surface a vertically extending dovetail portion whose horizontal width is likewise narrowed as the height of the same decreases for close fitting in the dovetail slot. The dovetail portion presents at a part thereof a horizontal surface portion, which is in abuttable engagement with an upper end of a holding member bodily formed on the bracket, so that the reservoir can be prevented from generating chatter relative to the bracket.

Claims

1. A resinous reservoir and attachment, comprising:

a vertically extending dovetail portion integrally formed on a lateral surface of said resinous reservoir and having a horizontal width portion which is narrowed as the height thereof decreases;

a mounting bracket;

means formed on said mounting bracket for defining a vertically extending dovetail slot whose horizontal width is narrowed as the height thereof decreases so as to permit said dovetail portion to be closely fitted therein;

means for preventing said dovetail portion from being upwardly removed from said dovetail slot;

a vertically extending rib integrally formed with and centrally disposed on said dovetail portion and defining said horizontal width portion at an upper end thereof, said rib also defining at a side portion thereof a radially inwardly slanted surface portion defining an undercut lower end thereon; and

said holding member overlying said horizontal width portion at an upper end thereof for preventing said dovetail portion from being upwardly removed from said dovetail slot and including a lower holding piece securely engaging said slanted surface portion at a lower portion thereof for preventing said reservoir from horizontally moving to and away from said bracket.

2. A resinous reservoir and attachment, comprising:

a vertically extending dovetail portion integrally formed on a lateral surface of said resinous reservoir and having a horizontal width portion which is narrowed as the height thereof decreases;

a mounting bracket;

means formed on said mounting bracket for defining a vertically extending dovetail slot whose horizontal width is narrowed as the height thereof decreases so as to permit said dovetail portion to be closely fitted therein;

means for preventing said dovetail portion from being upwardly removed from said dovetail slot; and

a vertically extending rib integrally formed at said dovetail portion and defining said horizontal width portion at an upper end thereof, said rib also defining at a side portion thereof a slanted surface portion having a lower end; and

a spring interposed between a lower portion of said holding member and said slanted surface portion for urging said reservoir horizontally away from said bracket;

an upper end of said holding member being engaged with said horizontal width portion for preventing said dovetail portion from being upwardly removed from said dovetail slot.
