Problems solved by technology

[0008] However, the gear transmission of the above-mentioned rotational driving force via the above-mentioned plurality of intermediate shafts not only leads to a complicated structure of the power transmission mechanism, but also increases the number of components such as gears, resulting in an increase in the size of the equipment, thereby reducing the transmission efficiency of the above-mentioned rotational driving force. losses also increased

Abstract

To simplify a rotational force transmission mechanism by reducing the distance between a rotary shaft of a starter motor and a crankshaft to decrease the number of intermediate shafts for the transmission of rotation driving force from the rotary shaft of the starter motor to the crankshaft. A recess 1a is formed in the upper part of a crankcase 1, and the starter motor 2 is placed in the recess 1a, thereby reducing the distance between the rotary shaft 2d of the starter motor 2 and the crankshaft. The transmission of rotation driving force from a gear of the rotary shaft 2d of the starter motor 2 to the crankshaft through an intermediate gear is achieved by one intermediate shaft 4 only, thereby simplifying the structure of the mechanism for the rotational force transmission.

Description

technical field [0001] The present invention relates to a mounting structure of a starter motor in an internal combustion engine, and more particularly to the above-mentioned internal combustion engine configured so that the arrangement positions of the starter motor and the crankshaft are close to each other, and the distance between the rotation shaft of the starter motor and the crankshaft is shortened. Starter motor installation structure. Background technique [0002] The starter motor in the conventional internal combustion engine is installed relative to the outline drawn by the crank case shell of the internal combustion engine, and is installed according to the relationship outside the outline, and the starter motor is arranged at a position far from the crankshaft. On the other hand, the distance between the rotation shaft of the starter motor and the two shafts of the above-mentioned crankshaft increases, and the transmission of the rotational driving force from t...
