Claim:
1. A method for manufacturing a resin hollow member having a hollow space internally, the method comprising: mating a pair of half hollow members to each other at mating surfaces to form a resin filling space between the mating surfaces, the half hollow members being formed of resin; and charging the resin filling space with melting resin and solidifying the melting resin, wherein each of the mating surface has a groove, which has a bottom surface in which a hole opens, the groove and the hole form the resin filling space between the mating surfaces when the half hollow members are mated to each other, and each of a wall surface of the groove and an inner periphery of the hole includes a melting projection, which is configured to be melted with heat of the melting resin and to be solidified with the melting resin, wherein each of the mating surfaces has a flat surface, the hole of each of the mating surfaces linearly extends along a specified direction perpendicular to the each of the mating surfaces, the melting projection of the inner periphery of the hole linearly extends along the specified direction, and the melting projection of the inner periphery of the hole has a tapered cross-sectional shape taken along a direction perpendicular to the specified direction with a width gradually narrowing toward a distal end of the melting projection.
