A supplemental tool for installation that can achieve both high magnetic-marker installation efficiency and high magnetic-marker installation accuracy is provided. A supplemental tool for arranging a magnetic marker in an accommodation hole provided by being drilled in a road surface includes a columnar-shaped retaining member including a retaining surface for the magnetic marker at an end portion in an axial direction and a detaching member combined with the retaining member so as to be able to move to the axial direction as opposed to the retaining member. A combination of the retaining member and the detaching member is such that detaching member can abut on the magnetic marker retained on the retaining surface, and it is configured so that the retaining member can retreat in the axial direction to a side away from the magnetic marker keeping a state in which the detaching member abuts on the magnetic marker.

Magnetic marker installation method and supplemental tool for installing magnetic marker

A sheet-shaped magnetic marker to be laid on a road surface so as to be able to be detected by a magnetic sensor attached to a vehicle to achieve assist for driving operation of the vehicle by a driver or control on a vehicle side to achieve automatic driving independently from operation of the driver has a magnet sheet () as a magnetism generation source and a wireless tag () which outputs information via wireless communication to the vehicle side. In the magnetic marker, the wireless tag () is interposed between a sheet (A) and a sheet (B) configuring the magnet sheet (), and the entire wireless tag () is accommodated inside the magnet sheet ().
