摘要： A construction machine has a locking mechanism for locking a lower end of a front part of a guard member onto a bracket while allowing a cab to be moved with elastic deformation of an anti-vibration mount. The locking mechanism has a shaft body across the bracket and the guard member vertically movably with the guard member. The shaft body has a stopper to be engaged to an upper frame side to restrict a moving amount of the shaft body to a stroke for shock absorbing. The bracket has a bolt insertion hole for a bolt to fix the bracket and a shaft body insertion hole for the shaft body. The bolt insertion hole is a lateral oblong hole extending in a direction inclined, with respect to the horizontal direction, toward a direction orthogonal to a load acting direction in the lateral rollover.
