Problems solved by technology

[0004] However, when the starting device is arranged on the driving wheel side, that is, on the rear wheel side, it must be moved to the rear position of the vehicle when starting.
Especially in the case of automatic tricycles, since the rear wheels are located on the left and right sides of the power head, the operating range (operating space) of the starting device will be limited by the rear wheels, which is also a problem

Abstract

Provided a starting device for a vehicular power unit arranged on the opposite side of a drive wheel shaft sandwiching a crankshaft for outputting rotational driving force to a transmission device. The power unit 6 has an engine 19 loaded on a three-wheeled motorcycle 1 for outputting rotational driving force from the crankshaft 26 arranged in parallel to a rear wheel shaft 33 with rear wheels 4L,4R connected thereto, and a transmission 37 for transmitting the rotational driving force of the crankshaft 26 via a counter shaft arranged in parallel to the rear wheel shaft 33. The power unit 6 isstructured by a kick shaft 49 arranged in parallel to the crankshaft 26, a kick arm 50 arranged at the tip end of the kick shaft 49, and a kick starting mechanism 28 for starting the engine 19 by rotating the kick shaft 49 by making the kick arm 50 kick and transmitting the rotation to the crankshaft 26. The kick shaft 49 sandwiches the crankshaft 26 and is arranged on the opposite side of the rear wheel shaft 33.

Description

technical field [0001] The present invention relates to a vehicle power unit starting device mounted on a small vehicle such as an auto tricycle. The vehicle power unit includes an internal combustion engine and a speed change device. Background technique [0002] Conventionally, in small vehicles such as motorcycles and tricycles, a starter device for starting an engine is arranged in the drive wheel direction with respect to the crankshaft (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2000-205091 [0004] However, when the starter device is arranged on the drive wheel side, that is, on the rear wheel side, it must be moved to a rear position of the vehicle when starting. Especially in the case of an automatic tricycle, since the position of the rear wheels is on the left and right sides of the power head, the operating range (operating space) of the starting device will be limited by the rear wheels, which is also a p...
