Kind Code:
A1
Abstract:
This handle is an injection-molded article comprising a resin material and includes a design surface determined in advance and non-design surfaces other than the design surface. The handle comprises an attachment section, a grip section, connection sections, and a gate mark. The gate mark indicates a mark at which the resin material is to be injected and is provided on the non-design surface of a second connection section. The distance from the attachment-section side at a first connection section is used as an attachment-section reference distance. The gate mark is provided on the non-design surface of the second connection section such that, with regard to an attachment-section reference distance/cross-sectional area characteristic obtained with the attachment-section reference distance being set as a horizontal axis and the cross-sectional area of the first connection section being set as the vertical axis, a weld section is positioned within a prescribed error range including a local minimum point of the cross-sectional area or within a range located on the attachment section side relative to the error range.
