Abstract

See full text

A structure for mounting a cooling fan (30) includes a spider (31) and blades (32) at free ends of mounting arms (31c) of the spider (31). A rotation center portion (31b) of the spider (31) is mounted on a rotating shaft (33) through a fan adaptor (60), the rotating shaft (33) being driven by an engine (27). A partition member (70) for closing gaps in the spider (31) is mounted on the fan adaptor (60). As a result of this configuration, the gaps between the mounting arms (31c) of the spider (31) can be reliably closed, and therefore the backflow of air from the downstream side (high pressure side) of the cooling fan (30) to the upstream side (low pressure side) thereof can be prevented.
