To mount a pedestal 12 for a pipe P on supporting members 11, 21 and 31 at a low cost and smoothly.

This pipe pillow, which is used when a pipe P, through which a power cable or a communication cable 'a' is passed, is mounted on a bridge or embedded underground, comprises a pedestal 12, that holds the pipe P against its outside circumferential surface and support members 11, 21, 31 that support the pedestal 12. A pin 3 with head is passed through the center of the base and the support members. A push nut 4 is press fitted to the top end of the pin 3 to make the pedestal 12 rotatable around the axis of the pin 3. The push nut 4 pushes and broadens the surrounding edge of a hole 4a via a slit 4b around the hole 4a to be fitted into the pin 3. Since the nut is integrated with the pin 3 with the elasticity of the surrounding edge, it can be mounted easily and at a low cost. Also, the dimensional error in the diameter of the pin 3 is absorbed by the degree of spaciousness of the hole-surrounding edge. Since the stop position in the longitudinal direction of the pin 3 is freely adjustable by degree of pushing, the degree of tightening can be obtained easily and arbitrarily.
