Claim 2:
3. A filter device, comprising:
a case which provides a fluid passage;
an element which is accommodated in the case and filters fluid in the fluid passage;
a water separator which is accommodated in the case and separates water from the fluid;
passage connecting members which form a fluid passage between the element and the water separator, and separably connect the element and the water separator;
a holding member which holds the water separator with respect to the case while making the water separator movable with respect to the case; and
a support member which movably supports the element by a movable distance in a radial direction, wherein
a movable distance of the water separator in the radial direction is set to be larger than the movable distance of the element, and
the passage connecting member includes:
an end pipe provided on either one of the element and the water separator, and a center bore provided on the other one; and
a coupling member provided between the element and the water separator, and wherein
the end pipe engages the element and the water separator in the radial direction by being inserted into the center bore, and wherein
the connecting member connects the element and the water separator so as to move together with respect to a circumferential direction, and wherein
the element and the water separator come into contact directly or indirectly with each other in an axial direction, and the water separator is pushed by the element.
