Abstract: A door panel that is capable of maintaining the adhering strength of the adhesive is provided. An outer panel and an inner panel are joined together by an adhesive. Adhesive retaining portions, each of which includes an adhesive retaining channel for retaining the adhesive, are provided in adhering portions of the inner panel. Each adhering portion includes vertically extending portions, and the adhesive retaining portions of the inner panel are formed in the shape of an extended raised portion and extend vertically in the respective vertically extending portions of the adhering portions, along ventilation openings, which are formed at locations corresponding to groups of ventilation holes of the outer panel. Each adhesive retaining portion is provided at the middle of each vertically extending portion of the adhering portions so as to be flanked by adhesion margins of identical width.
Abstract: The invention is an object of the invention to provide a strainer for an oil supply mouth, preventing the oil flowing when supplying the oil from colliding with the float so as to accurately detect the height of the liquid level. The strainer for an oil supply mouth of the invention has a guide hole equipped in vertical directions and a float for an oil level gauge passing movably in vertical directions through this guide hole. When the oil comes up to an at least reference liquid level, the float is received at a lower end within the guide hole.
