Abstract
In a swash plate hydraulic pump or motor structured so that a convex arc surface on the back surface of a swash plate is supported on a concave arc surface of a swash plate support via a bearing in a manner enabling the arc surface to swing in the circumferential direction that follows the arc path. A restricting pin is included for restricting movements of the bearing. The assembly structure prevents the restricting pin from coming out of the swash plate and the swash plate support. One end of the restricting pin is supported rotatably on a side surface of the swash plate. An intermediate portion of the restricting pin is engaged in an engagement hole formed in a holder of the bearing in a loosely fitting manner. Finally, the other end of the restricting pin is inserted into a support rod supported rotatably around its axis on the swash plate support to permit movement of the restricting pin in a pin axial direction.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
