Vehicle support structure
View Patent ↗In one embodiment of the invention, a recess portion is formed at an outer end portion of the upper surface of the arm member connecting portion, one end of the recess portion communicates with the counterbored portion, and the other end of the recess portion is opened to an exterior of the arm connecting member.
1. A vehicle support structure made of a non-ferrous light alloy comprising integrally:
a main body portion on which a vehicle member is mounted, and
an arm member connecting portion which continues to a lower portion of the main body portion so that a press fitting hole is provided into which a cylindrical member, which connects an arm member and which is made of an iron based metal, is press fitted and that a counterbored portion which one end of the press fitting hole faces is formed on an upper surface of the arm member connecting portion, wherein
a recess portion is formed at an outer end portion of the upper surface of the arm member connecting portion, and
one end of the recess portion communicates with the counterbored portion and the other end of the recess portion is opened to an exterior of the arm member connecting portion.
2. The vehicle support structure according to claim 1 , wherein
at least the upper surface of the arm member connecting portion is formed so as to be inclined in such a way as to be lowered as it extends towards an outer end thereof, and
the recess portion is formed at a lowermost portion of the upper surface.
3. The vehicle support structure according to claim 1 , wherein
the recess portion is formed so that a bottom surface thereof becomes lower than a bottom surface of the counterbored portion.
4. The vehicle support structure according to claim 1 , wherein
the recess portion is formed at the same time as the main body portion and the arm member connecting portion which are all formed by gravity casting.
