Abstract
A drain structure for a fluid filter includes a cap internally forming a drain hole. The cap receives a valve member urged by an urging means in a direction, in which the valve member blocks the drain hole. Normally, the drain hole is blocked with a drain member. When fluid is drained from the drain hole, the drain member is removed from the drain hole, and a drain tool is inserted into the drain hole, so that the drain tool displaces the valve member in a direction, in which the drain hole is unblocked. The drain tool has a hooking portion that can hook to a hooked portion provided to the cap by axially rotating the drain tool inserted into the drain hole of the cap. Thus, the drain tool can be connected with the cap while the hooking portion is supported by the hooked portion.
