Abstract
Object In a cab frame structure for a construction machine in which a front pillar and a roof pillar are configured by one tubular material, the cab frame structure for the construction machine in which an attachment position of a front header can be reversibly raised and an upward viewing angle of a driver is enlarged is provided. Solving Means A front pillarand a roof pillar, which constitute a cab frame of the construction machine, are configured by one tubular materialhaving a curved portionat a joint between them, and by making a curvature radius of a curve outer sidein the curved portionsmaller than a curvature radius of a curve inner side, a spaceto raise an accommodation position of a top endof a front window unitis formed in the curved portion. A front headeris arranged at the position of the top endof the front window unitaccommodated in the space. With this configuration, the attachment of the front headercan be reversibly raised, and an upward viewing angle θof a driver can be expanded.
