Sensor bracket

A sensor bracket comprising:

• a sensor hood extending in a detecting direction from a side of a detection unit of an external field-detecting sensor configured to detect electromagnetic waves, and surrounding a detection space through which a detection center axis of the detection unit passes,
• wherein the sensor hood comprises a front surface-forming section that forms a flat front surface facing the detection space,
• the front surface-forming section comprises a fixed body including a part of the front surface and a split body including another part of the front surface and configured to be separable from the fixed body,
• where a direction perpendicular to the detecting direction in the front surface when seen in a plan view is referred to as a surface width direction, a direction perpendicular to the surface width direction in the front surface when seen in the plan view is referred to as a surface forward/rearward direction, and a direction perpendicular to the surface width direction and the surface forward/rearward direction is referred to as a height direction,
• when seen from the height direction, a split section between the fixed body and the split body divides the front surface into a first range including the detection center axis in the surface width direction and a second range that avoids the detection center axis,
• the first range is disposed at the same height as the second range in the height direction or disposed closer to the detection center axis than the second range, and
• the first range of the front surface is disposed further inside the front surface in the surface width direction than the split section, and constituted by the split body.
