Claims

[Claims for Utility Model Registration] 1. A fan 7 and a fan case 8 are provided on one side of the air-cooled engine 1, a dustproof case 10 is fixed to the outer end surface of the fan case 8, and a dustproof case 10 is attached to the eccentric protrusion 12 of the dustproof case 10. The air intake port 13 is opened, and the outside air is drawn into the dust-proof air intake port 1 by the blowing action of the fan 7.
A recoil starter 15 is provided in the center of the dustproof case 10, and a recoil starter 15 is installed in the center of the dustproof case 10 to prevent the recoil from flowing. Starting wheel 16 with starter 15
The air-cooled engine 1 is started by rotating the engine rotating shaft 6 through 12 are formed near the proximal end on both sides of the dustproof case 10, and both the drawer openings 21 and 22 are connected by a rope moving groove 23 for switching the direction of handle pullout operation, and the rope moving groove 23 is formed on the outer end surface of the dustproof case 10. The part near the proximal end of the eccentric protrusion 12 is run across, and the pull-out end 20a of the starting rope 20 is passed through the rope moving groove 23 to both pull-out ports 21, 2.
In the device for changing the pulling direction of the starting handle 25 for a recoil starter of a forced air-cooled engine, the pulling direction of the starting handle 25 is changed by switching between the rope moving groove 23 and the mud-proof cover 32. This device is characterized in that the mud-proof lid 32 is biased toward the closing side by a closing biasing means 33, and the starting handle pull-out operation direction changing device for a recoil starter for a forced air-cooled engine is provided. 2. A rope sliding contact surface 41 for keeping the lid open is provided over almost the entire length of the opening tip edge 40 of the mud-proof lid 32, and rope sliding surfaces 41 for opening the lid are provided at both ends of the opening tip edge 40 of the mud-proof lid 32, respectively. Rope contact surfaces 42 and 43 are provided, and when the starting rope 20 of the recoil starter 15 moves from one of the draw-out ports 21 and 22 to the other via the rope moving groove 23, there is a process in which the starting rope 20 enters the rope moving groove 23. The rope comes into contact with each of the opening rope contact surfaces 42 and 43 to push the mud-proof lid 32 open against the closing lid biasing means 33, and in the process of moving through the rope moving groove 23, the opening lid The starting handle pull-out operation direction changing device for a recoil starter for a forced air-cooled engine according to claim 1, configured to keep the mud-proof lid 32 open by slidingly contacting the holding rope sliding surface 41.
