Embodiment Construction

[0036] Below, according to Figure 1 to Figure 7 One embodiment of the present invention will be described.

[0037] figure 1 It is an overall side view of the motorcycle 1 of this embodiment.

[0038] In the body frame of the motorcycle 1, a pair of left and right main frames 3, 3 extend slightly downward from the head pipe 2 to the rear, and then bend downward to form steeply inclined portions 3a, 3a, so that the lower part is bent forward to form a word, until the lower end.

[0039] In addition, the pair of left and right lower frames 4 , 4 extend downward from the head pipe 2 at an acute angle, and extend parallel to the steeply inclined portion 3 a of the main frame 3 in side view.

[0040] Seat arm bars 5, 5 extend rearward from the upper part of the steeply inclined parts 3a, 3a of the main frame 3, 3, and connect the central part of the seat arm bars 5, 5 with the rear pillars at the lower parts of the steeply inclined parts 3a, 3a. 6,6 support the seat armrest 5,...

Abstract

An distribution structure of starting motor in an internal combustion engine is provided, which avoids the big size of an internal combustion engine equipped with tightener of roller chain and is integrated with the engine compactly. In the internal combustion engine which provided a annular roller chain (43) located between a drive sprocket (32) embedded in the crankshaft and a driven sprocket (32) embedded in the camshaft, the push rod(56) compressing against the thrust part (51) of thrust roller chain (43) is configured as rod axes (Lr) which forms an obtuse angle with the cylinder axes (Lc) of cylinder(23) being vertically set in the crankcase (22) at the front side of the engine, and a starting motor (70) is arrange at the front of the crankcase (22) thereof.

Description

technical field [0001] The present invention relates to a starter motor arrangement structure of an internal combustion engine, which includes a cam chain tensioner composed of a pressing device that presses a roller chain that transmits power to a valve system, and a push rod that is in pressure contact with the pressing device. Background technique [0002] When a roller chain is used as a cam chain, the frictional force is lower than that of a silent chain, but bulky equipment such as a pusher or a push rod is required instead, and it is difficult to arrange a starter motor without increasing the size of the internal combustion engine. [0003] An example of an internal combustion engine using such a roller chain and a cam chain tensioner such as a pusher or a push rod is disclosed in Patent Document 1. [0004] Patent Document 1: Japanese Patent No. 4035226 [0005] In the internal combustion engine disclosed in this Patent Document 1, cylinders protrude substantially h...
