Abstract: A mesh filter includes a circular plate-shaped mesh portion having a plurality of openings allowing a fluid to pass, a ring-shaped frame body supporting an outer periphery of the mesh portion, and a button-shaped thick portion positioned on an inner peripheral side of the mesh portion. The frame body includes a gate detachment part at one place in a circumferential direction. The mesh portion includes a plurality of inner ribs and outer ribs symmetrical with respect to an imaginary straight line passing through a center of the gate detachment part and bisecting a planar shape of the frame body. The four inner ribs are formed at regular intervals in a peripheral area of a center axis of the thick portion. The outer ribs extend radially inward from an inner peripheral surface of the frame body and are separately formed on both sides of extended lines of the respective inner ribs.

Abstract: A gear includes: an outer circumferential rim provided integrally with a plurality of tooth portions disposed side-by-side in a circumferential direction on an outer circumferential surface; and a plurality of reinforcing ribs disposed inside the outer circumferential rim to be spaced from each other in the circumferential direction by thinning portions, wherein a position where each of the plurality of reinforcing ribs and the outer circumferential rim are joined corresponds, in the circumferential direction, to a position of a tooth groove between the plurality of tooth portions.

Abstract: A resin gear includes a web with a side surface on which a first annular rib and a second annular rib are formed to be concentric with a boss. The web has an inner web portion coupling the first annular rib to the second annular rib, and an outer web portion coupling the second annular rib to a rim. The inner web portion is formed to have a thickness gradually reduced from one intersection point toward another intersection point, the intersection points being intersection points of a virtual radial direction line passing through a center of the boss with the second annular rib. The first annular rib has a side surface on which only one gate mark of an injection molding is formed at a position on a radially outer side with respect to a first tooth portion and a position biased to the other intersection point on the virtual radial direction line.
