Abstract:
A coupling plate is arranged below an attaching member. A vibration suppressing member is mounted between the attaching member and the coupling plate. The first controller main body is arranged above the attaching member. A coupling member connects the coupling plate and the first controller main body.
Abstract:
An operator protective guard which can ensure strength and is easily manufactured and assembled is provided. A front guard includes a plurality of first plate members and second plate members each made of one plate. The first plate members and the second plate members are assembled in a grid pattern such that a first longitudinal direction of each of the first plate members intersects with a second longitudinal direction of each of the second plate members. The plurality of the first plate members are arranged radially as seen in the longitudinal direction. The plurality of the second plate members are arranged radially as seen in the longitudinal direction. A slit is formed in the first plate member, and the second plate member is fitted in the slit and fixed by welding.

Abstract:
A controller assembly is mounted on a side wall surface extending in an upward/downward direction of a hydraulic excavator. The controller assembly includes a controller main body, a first bracket, a second bracket, and a vibration suppressing member. The first bracket is mounted on the side wall surface described above. The second bracket is fixed to the controller main body. The vibration suppressing member supports the first bracket at one end in the upward/downward direction, and supports the second bracket at the other end in the upward/downward direction so as to be movable with respect to the first bracket.
