<p>It is an object of the present invention to make it possible to automatically assemble a shaft assembly of a swash plate-type fluid machine regardless of whether or not there is a center hole formed in each of end surfaces of each of pistons. By using an assembly device (A1) for an assembly, a shaft assembly (S) having a plurality of pistons (2) each installed on an outer peripheral portion of a swash plate (3b) via shoes (4) is assembled. This assembly device (A1) has a shaft support portion (41) for supporting a shaft (3) having the swash plate (3b) in a vertical axis posture, a guide member (20), a shoe incorporation mechanism (30), a carriage (10) for conveying the plurality of pistons (2) in the vertical axis posture, and a piston holding portion (41) for holding the plurality of pistons (2), which are guided to the outer peripheral portion of the swash plate (3b), at circumferentially equidistant positions of the swash plate (3b), respectively, in the vertical axis posture. The guide member (20) is equipped with a first guide surface (22) and a second guide surface (23). The guide member (20) guides each of the pistons (2) to the outer peripheral portion of the swash plate (3b) to match a pair of the shoes (4) with both end surfaces of the swash plate (3b), respectively, while holding one of the pair of the shoes (4) incorporated in a neck portion (2a) of that piston (2) in slidable contact with the first guide surface (22) and another shoe (4) in slidable contact with the second guide surface (23). The shoe incorporation mechanism (30) inserts the pair of the shoes (4) between the piston (2) and the first guide surface (22) and between the piston (2) and the second guide surface (23), respectively.</p> |
