A bracket attaches a heat exchanger to a supporting member. The bracket includes a vibration-proof member, and first and second bracket members. The first member is fixed to the supporting member. The second member is joined to a projection of the heat exchanger through the vibration-proof member. The second member is attached to the first member. The second member includes a joining part and an attaching part. The projection is inserted in the joining part from a projecting direction of the projection so that the joining part is joined to the projection with the vibration-proof member intervening therebetween. The attaching part is inserted in the first member from a direction that intersects with a joining direction in which the joining part is joined to the projection, so that the attaching part is attached to the first member at an arbitrary position of the first member in the joining direction.
