Title:
CAB PROTECTIVE STRUCTURE IN WORK MACHINE
Document Type and Number:
Japanese Patent JP2015168936
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To secure required strength, even if a size of a stopper is reduced, when constituting a regulation device for regulating displacement of a cab by using a stopper receiving part provided in a machine body frame and/or a cab bottom part and forming a through-hole in a central part, a shaft of penetrating through the through-hole of the stopper receiving part and the stopper supported by the shaft.SOLUTION: An abutting side surface with a stopper receiving part 7 of a stopper 10 is formed as a spherical surface 10a, and when a cab 2 is displaced in the direction for separating from a machine body frame 1, the spherical surface 10a of the stopper 10 is constituted so as to abut in a slipping-out preventive shape on a peripheral part of the through-hole 7a of the stopper receiving part 7.
