Title:
BLADE, WORK MACHINE, AND MANUFACTURING METHOD OF BLADE
Document Type and Number:
Japanese Patent JP2022011360
Kind Code:
A
Abstract:
To improve durability while ensuring cutting performance.SOLUTION: A blade 50 has a blade body 52. The blade body 52 has a general part 52D constituting a front part of the blade body 52 and a narrow part 52C constituting a rear part of the blade body 52. The width dimension of the narrow part 52C is set smaller than the width dimension of the general part 52D. As a result, even if the width dimension of the blade body 52 is made relatively large, the interference between the blade 50 and an opening of a saber saw can be suppressed by the narrow part 52C. Further, a thin wall part 52G is formed on a back part 52A of the blade body 52, and a thin wall part 52G is formed on the general part 52D and the narrow part 52C of the back part 52A. As a result, one end in a width direction of the blade body 52 is extended over substantially the entire longitudinal direction, and thereby, the blade body 52 is satisfactorily curved so that an intermediate part in the longitudinal direction of the blade body 52 projects to one side in the width direction.SELECTED DRAWING: Figure 2
