<p>PURPOSE: To change an existing engine drive type unit into a hybrid type power unit by attaching a motor drive type unit by switching power between a V-belt type power transmission system and a power transmission system for motor and driving the hybraid type power unit by power of either motor or engine. CONSTITUTION: A unit 42 for driving motor which includes a motor 40 and a power transmission system 41 which transmits power to a drive shaft in one unit is provided on the opposite side across a rear wheel 14 of a V-belt type power transmission device 24. By switching power between the V-belt type power transmission system 24 and a power transmission system for motor 41 by a switching mechanism, a hybrid type power unit can be driven by power of either motor 40 or engine 21. Consequently, it is possible to change an existing engine drive type unit into the hybrid type power unit 20 by attaching a motor drive type unit 42.</p> |
