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.
