COATING MECHANISM AND IMAGE FORMING APPARATUS

To provide a coating mechanism that brings a coating member into pressure contact with a surface having an object to be coated to coat the object to be coated, and even when the mechanism has a structure that overlaps the object to be coated in plan view in a normal direction, can coat the entirety of the object to be coated.SOLUTION: A coating mechanism comprises: a surface to be pressure-contacted 50 that has an object to be coated 51; a coating member 30 that has a lid-like part 33; a pressing member 40 that presses the coating member 30; and side walls that define a space for accommodating the coating member 30 and the pressing member 40. The side walls have a first side wall 61 that supports the coating member 30 and a second side wall 62 that supports the pressing member 40. The first side wall 61 has a projection 71 that projects to overlap the object to be coated 51 in plan view in a normal direction of the surface to be pressure-contacted 50. The second side wall 62 has an engaging support part 72 that is engaged with the pressing member 40. The pressing member 40 engaged with the engaging support part 72 to be fixed presses the coating member 30, and the lid-like part 33 of the pressed coating member 30 is fitted between the surface to be pressure-contacted 50 and the projection 71 and brought into pressure contact with the surface to be pressure-contacted 50.SELECTED DRAWING: Figure 2 【課題】被覆対象を有する面に対し被覆部材を圧接させて被覆する構成において、法線方向の平面視で被覆対象に重なる構造を有する場合であっても、被覆対象全体を被覆可能な被覆機構を提供する。【解決手段】被覆対象５１を有する被圧接面５０と、蓋状部３３を有する被覆部材３０と、被覆部材３０を押圧する押圧部材４０と、被覆部材３０及び押圧部材４０を収容する空間を画成する側壁とを備え、被覆部材３０を支持する第一の側壁６１と押圧部材４０を支持する第二の側壁６２とを有し、第一の側壁６１は、被圧接面５０の法線方向の平面視で被覆対象５１に重なるように突出した突出部７１を有し、第二の側壁６２は、押圧部材４０と係合する係合支持部７２を有し、係合支持部７２により係合固定された押圧部材４０が被覆部材３０を押圧し、押圧された被覆部材３０の蓋状部３３が被圧接面５０と突出部７１との間に嵌入するとともに被圧接面５０と圧接する被覆機構。【選択図】図２
