Mouthful, and become the state allowing the discharge based on the coolant in the radiator 61 of discharging tube 71, by obturation
The opening of the other end of discharging tube 71, becomes cut-out based on the coolant in the radiator 61 of discharging tube 71
The state discharged.
Additionally, be used as the valve member of tap etc. to replace bleed plug 77.
As shown in Fig. 4 (a), Fig. 4 (b), Fig. 5 (a) and Fig. 5 (b), before radiator 61
Side is configured with fuel tank 80.Be configured with engine 11 in the left of radiator 61, radiator 61 with start
It is configured with fan shroud 81 between machine 11.
The two ends, left and right of fan shroud 81 have the quadrangular barrel shape of opening.Rear side at fan shroud 81 is formed
There is the service ports 82 (with reference to Fig. 7 (a)) in the space connecting in fan shroud 81 and the outside of fan shroud 81.Maintenance
Cover 83 circumferential lateral surface being installed on fan shroud 81 with the state blocking service ports 82.Service cover 83 is can opening and closing
The component of service ports 82, and constitute with freely loading and unloading in the circumferential lateral surface of fan shroud 81.
Hereinafter, illustrate with regard to the mounting structure between fan shroud 81 and service cover 83.As Fig. 7 (a),
It shown in Fig. 7 (b) and Fig. 7 (c), is formed with the protuberance 84 highlighting downwards in the lower end of service cover 83,
It in the lower section of the service ports 82 of fan shroud 81, is formed with the embedded division 85 of the protuberance 84 that can embed service cover.
Service cover 83 embeds the embedded division 85 of fan shroud 81 at its protuberance 84, and protuberance 84 is by protuberance 84
And in the state of inserting elastic component 86 between embedded division 85 and be pressed against the circumferential lateral surface of fan shroud 81,
The 87th, its top by with screw 87 being tightened against fan shroud 81 (above service ports 82) thus being installed on fan shroud
81.Thus, service ports 82 becomes the state being blocked by service cover 83.
In addition, service cover 83 is from the state being installed on fan shroud 81, by unloading screw the 87th, 87, from embedded
Its protuberance 84 is extracted in portion 85, and unloads from fan shroud 81.Thus, service ports 82 becomes the state opened.
As shown in Fig. 4 (a), Fig. 4 (b), Fig. 5 (a) and Fig. 5 (b), the left end of fan shroud 81
Opening the cooling fan (exhaust fan) 88 of engine 11 is covered, the opening of the right-hand member of fan shroud and heat radiation
Device 61 is close to.Thus, the cooling fan 88 of engine 11 is connected by fan shroud 81 with radiator 61.
