Abstract
A heating cylinder cover for covering a heating cylinder includes a temperature control mechanism in which at least a plurality of heating units are provided on an outer circumferential surface of a heating cylinder body along an axial direction. The heating cylinder cover includes a heat-retaining cover part that is integrally provided with a cover body part and a plurality of partition parts. The cover body part is attached to the heating cylinder thereby forming a predetermined covered space between the cover body part and the temperature control mechanism and covers at least an upper half part of the heating cylinder. The partition parts project from an inner surface of this cover body part toward the temperature control mechanism and divides the covered space into a plurality of closed spaces.
