Title:
PROPELLER SHAFT
Document Type and Number:
WIPO Patent Application WO/2023/162418
Kind Code:
A1
Abstract:
A propeller shaft (PS) according to the present invention is provided with a minimum diameter recess (71) in a stub shaft part (12) of a first shaft member (1) at a position overlapping a vehicle mounting member (5) such that the minimum diameter recess (71) forms a weakest part (WP) having the lowest torsional strength in the first shaft member (1), which includes a first joint member (J1). For this reason, there is no fear in that a first drive-side joint member (J11) may constitute the weakest part (WP) in the first shaft member (1) and a torsional strength of the first drive-side joint member (J11) can be secured so as to be higher than the torsional strength of the stub shaft part (12).
