Embodiment Construction

[0023] Embodiments of the present invention will be described based on the drawings. In the drawings, reference numeral 1 denotes an excavator, which is an example of a work machine. The excavator 1 includes a crawler-type lower travel body 2 , an upper swivel body 3 mounted on the upper swivel body 3 , and a front working portion 4 supported by the lower travel body to be slewable. The upper slewing body 3 further includes a cab 5 serving as an operator's cab, an engine room 6 accommodating various equipment (not shown) such as an engine therein, and a counterweight 7 .

[0024] The engine room 6 is covered at the top side by an upper cover 8 and at laterally opposite sides by side covers 9 . The upper cover 8 has an opening 8 a for maintenance, through which observation, maintenance and the like are performed on equipment housed in the engine room 6 . The opening 8a for maintenance is covered by an openable and closable engine hood 10 .

[0025] The engine compartment 6 c...

Abstract

PROBLEM: To provide a rubber stopper which can be mounted easily to an opening-closing cover and prevent the rubber stopper coming off from the opening-closing cover with vibration of a machine, the rubber stopper that is attached to the opening-closing cover with pressure while the opening-closing cover is locked to the closed position, the opening-closing cover that covers an opening part of a cover body opened / closed freely, the cover body that covers a storage room. SOLUTION: A rubber stopper (18) is formed with a body part (18b) having an attach surface part (18a) to attach a cover body (8), a mounting leg part (18c) to put into a mounting part hole (20b) formed on the mounting part (20) penetratingly and a recessed portion for tucking (18d) formed on the attach surface part (18a) positioned aligned with the mounting leg part (18c) in the front back direction, and the rubber stopper (18) is mounted to the mounting part (20) by putting the mounting leg part (18c) to the mounting part hole (20b).

Description

technical field [0001] The present invention relates to the technical field of a rubber stopper for opening and closing covers, such as engine hoods provided on work machines such as construction machines. Background technique [0002] In general, some working machines such as construction machines include a cover covering a case room (engine room, etc.) in which equipment such as an engine is housed, the cover having an opening for maintenance, An opening and closing cover (hood, etc.) that is opened and closed to cover the opening, and a locking device for locking the opening and closing cover in a closed position. [0003] When the working machine having such an opening and closing cover is a construction machine such as an excavator, the opening and closing cover vibrates jointly with the vibration of the machine body due to traveling or running on a rough work site. Then, noise may be generated, and the sealing material forming the seal between the opening and closing ...
