PROBLEM TO BE SOLVED: To provide a filter for a water supply device for pets which can obtain sufficient filtering performance.SOLUTION: A filter for a water supply device for pets according to this invention includes: a filter tray 6 in which an outer peripheral wall 62 and an inner peripheral wall 63 are respectively provided on an outer peripheral edge part and an inner peripheral edge part of a bottom wall 61, and a plurality of partitioning walls for partitioning a part between the outer peripheral wall 62 and the inner peripheral wall 63 into a plurality of inner part filtering chambers in a circumferential direction are provided on the bottom wall 61 and an upper surface covering filter material 72 for covering an upper end opening part of the filter tray 6. The partitioning wall includes: a main partitioning wall 65 in which an outer end edge is connected to the outer peripheral wall 62, and an inner end edge is arranged in a position separated from the inner peripheral wall 63 a bifurcating base end wall 66 which is branched into two from the inner end edge of the main partitioning wall 65 and is arranged to extend to both sides in the circumferential direction and a bifurcating tip end wall 67 in which an outer end edge is connected to the bifurcating base end wall 66, and an inner end edge is arranged to be connected to the inner peripheral wall 63. The upper surface covering filter material 72 is firmly attached to the main partitioning wall 65 and the bifurcating tip end wall 67.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2018,JPO&INPIT【課題】十分な濾過性能が得られるペット用給水器のフィルターを提供する。【解決手段】本発明のペット用給水器のフィルターは、底壁61の外周縁部および内周縁部に外周壁62および内周壁63が設けられ、底壁61に外周壁62および内周壁63間を周方向に複数の内部濾過室に仕切る複数の仕切壁が設けられたフィルタートレイ6と、フィルタートレイ6の上端開口部を被覆する上面被覆濾材72とを備える。仕切壁は、外端縁が外周壁62に連結され、内端縁が内周壁63から離間した位置に配置された主仕切壁65と、主仕切壁65の内端縁から二股に分岐して略周方向に沿って両側に延びるように配置された二股基端壁66と、外端縁が二股基端壁66に連結され、内端縁が内周壁63に連結されるように配置された二股先端壁67とを備える。上面被覆濾材72は主仕切壁65および二股先端壁67に固着される。【選択図】図6
