Abstract: A coil spring includes a wire rod including a round section portion and a flat section portion. The round section portion includes a first cross section whose cross section is round. The flat section portion includes a second cross section that is flat. The second cross section has a width greater than or equal to the diameter of the first cross section and a thickness less than the width. A polar moment of inertia of area of the second cross section is smaller than that of the first cross section.

The variable section portion changes its cross section from circular to flat from the round section portion towards the flat section portion.

Abstract: A management apparatus includes a memory, a unification policy setting unit, and a security level setting unit. The memory stores, for each of a user belonging to a first group and a user belonging to a second group, an authentication level of a domain assigned to a corresponding one of the users. The unification policy setting unit sets a unification policy that specifies a relationship between the authentication level and a security level for a state after unification. The security level setting unit sets the security level in a case where the first group and the second group undergo the unification into a third group. The security level is set for each of the users belonging to the third group by using the authentication level and the unification policy.
