Abstract
An automatic choke device of a carburetor includes a wax attached to an engine main body, a rod configured to perform a linear motion in conjunction with expansion of the wax, a choke lever configured to rotate in conjunction with the linear motion of the rod, and a choke shaft arranged so as to be able to abut against the choke lever and connected to a choke valve of the carburetor. The choke lever includes a flat portion that engages with an engaging portion of the choke shaft, and a circular arc portion that is formed in a circular arc shape so as to be continuous from the flat portion and is brought into sliding contact with the engaging portion of the choke shaft.

An automatic choke device of a carburetor comprising:
- a wax attached to an engine main body;
- a rod configured to perform a linear motion in conjunction with expansion of the wax;
- a choke lever configured to rotate in conjunction with the linear motion of the rod;
- and
- a choke shaft arranged so as to be able to abut against the choke lever and connected to a choke valve of the carburetor, wherein
- the choke lever includes a flat portion that engages with an engaging portion of the choke shaft, and a circular arc portion that is formed in a circular arc shape so as to be continuous from the flat portion and is brought into sliding contact with the engaging portion of the choke shaft,
- the choke valve is opened in conjunction with the expansion of the wax by rotating the choke lever in a state where the flat portion of the choke lever engages with the engaging portion of the choke shaft, and
- after the choke valve is fully opened, an overstroke of the wax is absorbed without rotating the choke shaft by bringing the circular arc portion of the choke lever into sliding contact with the engaging portion of the choke shaft.
