<p>In a case structure for a fluid pressure device, a filter (12) that constitutes part of a fluid pressure unit (10) is equipped with a first body (20), a case unit (22) connected to a lower portion of the first body (20), and a filter unit (24) accommodated in the interior of the case unit (22). The case unit (22) is made up from an outer case (40), which is formed as a bottomed cylinder from a light-permeable transparent material, and an inner case (42) inserted into the interior of the outer case (40). Additionally, by insertion of the case unit (22) into an installation hole (36) that opens on a lower portion of the first body (20) and rotating the case unit (22), projections (58) and retaining walls (56) provided on an outer circumferential surface of the case unit (22) engage with support members (38) provided in the installation hole (36), thus placing the case unit (22) in a connected state.</p> |
