Abstract

PURPOSE:To restrain an engine from being swung upwards at the time of collision so as to prevent a cowl section from being deformed by forming an impact absorbing section with diameter smaller than that of other sections at a portion of a propeller shaft transmitting the output of an engine to driving wheels. CONSTITUTION:An impact absorbing section 19 consisting of a constricted section 19a with diameter smaller than that of other sections and of a swelling section 19b, is formed in the front section of a propeller shaft 10. As a result, when an engine 2 is pushed backward at the time of head-on collision, the impact absorbing section 19 of the propeller shaft 10 is deformed into a collapsed form for absorbing impact energy. Resultantly, this constitution can prevent both the engine 2 and a transmission 3 effectively from being swung upwards with fulcrum at an universal joint 11. And this constitution can also prevent a cowl section 4 from being deformed, thereby preventing a front glass 7 from being slipped off or destroyed.

(Problem to be Solved by the Invention) However, when the above-mentioned FR type moving vehicle J'3 causes a head-on collision, the engine is pushed from the front to the rear by the impact energy at that time. Since the rearward movement is restricted by the propeller shaft, it will be able to rotate significantly upward using the joint that connects the output shaft of the engine and the propeller shaft as a fulcrum. As a result, the cowl portion disposed above the engine interferes with the cowl portion, deforming the cowl portion, and causing the windshield, the lower portion of which is supported by the cowl portion, to shift or break.
There was a problem.
