Claim:
1. A vehicle body reinforcement apparatus extending along at least one of a front-rear direction and a width direction of a vehicle body, the vehicle body reinforcement apparatus comprising: at least two brackets via which the vehicle body reinforcement apparatus is fixed to the vehicle body; a housing connected to one of the two brackets; a rod including a first end portion that is movably housed within the housing and a second end portion connected to the other of the two brackets; a spring member disposed between the first end portion of the rod and the housing and applying a biasing force to the rod against a force for increasing and decreasing a distance between the two brackets in an axial direction of the rod; and a friction mechanism mounted to the housing and pressing the rod in a direction orthogonal to the axial direction of the rod, wherein the spring member is constituted by a single compression coil spring wound around the first end portion of the rod, the compression coil spring including a first axial end portion supported at a first axial position of the rod and a second axial end portion supported at a second axial position of rod, the second axial position being apart from the first axial position by a predetermined distance, the first axial end portion and the second axial end portion of the compression coil spring being supported at a first engagement portion and a second engagement portion which are formed to be spaced away from each other by the predetermined distance within the housing, and wherein the housing includes a first tubular member supporting the rod to be movable in the axial direction and holding the friction mechanism, the first tubular member joined to the first engagement portion, and the housing includes a second tubular member joined to the first tubular member and including the second engagement portion.
