PRESS MEMBER STRUCTURE

PROBLEM TO BE SOLVED: To provide a press member structure capable of realizing enhancement of rigidity (strength) in a recessed part for part insertion arrangement of a press member (for example, an engine mount member) without causing an increase of cost and an increase of weight only by adopting relatively simple constitution. SOLUTION: The press member structure is constituted such that the recessed part 8 for part insertion arrangement recessed to a curved shape is formed on the press member (for example, engine amount member body 14) formed by binding an upper plate 2 and a lower plate 3 each other and a load from a periphery part (for example, a load applied through an engine mount bracket 5) is received by a side part of this recessed part 8. A radius R1 of curvature at a center part S1 , i.e., the deepest part of the recessed part 8 is set to a larger value than a radius R2 of curvature at both side positions S2 of the center part S1 .
