Zusammenfassung: | The cord-type mowing machine is configured as follows: a body has a pillar; a reel is interpolated to the pillar; a ratchet wheel is interpolated to the pillar, and is stored inside the reel, and is rotated in a direction same as that of the reel; a ring is attached to the upper side of the reel; an upper cap is fixed to the upper end of the pillar; noreturn projections are successively formed on the undersurface of the upper cap; the ratchet wheel has a gathering pallet and is pressed toward the upper cap by a coil spring and the gathering pallet of the ratchet wheel is locked in a noreturn projection toward the letting-out direction of the cord; when the ratchet wheel falls due to a shock, locking between the gathering pallet and the noreturn projection is unlocked and the reel becomes rotatable in the letting out direction; the ring has an unlocking projection; when the ring is rotated in a winding direction, the gathering pallet climbs over the noreturn projection and the reel rotates in the winding direction; when the ring is rotated in the letting-out direction, the unlocking projection comes into contact with the gathering pallet; with the ratchet wheel pushed downward, the locking between the gathering pallet and the noreturn projection is unlocked and the reel becomes rotatable in the letting-out direction. |
