What is claimed is: 1. A filter device comprising a fixed head (1) having a feed liquid inlet and/or an outlet for filtrate, a stationary base member (2, 3), a first link (7) having one end pivotally mounted on the stationary base member at a first axis (5) , a second link (11) supported by the first link, a housing support member (12) supported by the second link, and a housing (15) supported by the housing support member, said housing having a space with an open top end for housing a filter element, a manipulation handle (17) fixed to the housing (15) or the housing support member (12), and a connector means (19) for connecting the top end portion of the housing to the fixed head (1) , said housing (15) is movably supported by the housing support member (12) having a means for allowing the housing (15) to move relative to the housing support member by a distance necessary for connecting the connector means (19) to the fixed head (1). 2. The filter device according to claim 1, wherein said means for allowing the housing to move is composed of a sleeve (29) for supporting the upper portion of the housing, and a resilient member ( 30) inserted between the sleeve (29) and the housing support member (12). 3. The filter device according to claim 1, wherein said first link (7) extends generally upward along a vertical line from the first axis (5) when the upper end portion of the housing (15 ) is engaged with the fixed head (1). 4. The filter device according to claim 1, wherein said first link (7) is swingable in a range between a vertical line passing through the first axis (5) and a tilted position where the filter element can be exchanged. 5. The filter device according to claim 1, wherein said second link (11) is pivotally mounted on the first link (7) at a second axis (9). 6. The filter device according to claim 1, wherein said second link (11) is pivotally mounted on the housing support member (12) at a third axis (13) and the second link ( 11) has an abutting portion (21) which is capable of abutting against said housing, whereby the housing is maintained in a vertical posture by gravity during steps prior to abutment of the abutting portion against the top portion of the housing and after disengagement from the top portion of the housing, and is held in tilted posture in the abutted condition. 7. The filter device according to claim 1, wherein the angle of said second link (11) is restricted in a range capable of allowing the tilting of the housing. 8. The filter device according to claim 1, wherein said first axis (5), the second axis (9) and the third axis (13) are in mutually parallel relation. 9. The filter device according to claim 1, wherein said stationary base member (3) is provided with a stopper (23), and said second link (11) is provided with an engaging portion ( 25) capable of engaging the stopper at a lowermost position of the tilted housing. 10. The filter device according to claim 1, wherein said fixed head (1) is provided with a male thread (27) on its outer periphery, and said connector ring (19) is provided with a female thread (20) on its inner periphery.
