Abstract
The present invention is to provide a vehicle-mounted apparatus having a biasing structure using a coil spring capable of reducing a lateral force of a coil spring that is applied to a biasing target member. When N1, n1, N0, and n0 represent the number of effective turns when the relief valve spring 37 is set in a valve hole 34 of a spool 29 in a compressed state, a value of an integer of N1, the number of effective turns when a length of the relief valve spring 37 is a natural length, and a value of an integer of N0, respectively, the spring 37 satisfies an equation 1: 0≤N1−n1≤0.25 or an equation 2: 0.75≤N1−n1<1.
