Distance sensor module

A distance sensor module, comprising:

• a distance sensor;
• and
• a housing,
• the distance sensor including:
• a sensor body;
• and
• a transmission and reception section connected to the sensor body and configured to emit a detection signal toward a measurement target and receive the detection signal as reflected by the measurement target,
• the distance sensor being of a non-contact type such that the sensor body is configured to measure a distance between the distance sensor and the measurement target as a result of the transmission and reception section receiving the detection signal,
• the housing including:
• a sensor container section containing the distance sensor;
• and
• an attachment section configured to attach the sensor container section to an external attachment target,
• the distance sensor being suspended from the housing with use of a holder plate,
• the sensor container section being configured to keep the transmission and reception section so oriented due to gravity as to have a vertically downward detection direction with the attachment section attached to the attachment target,
• the distance sensor being contained in the sensor container section in such a manner as to be capable of swinging to change an orientation relative to the housing,
• the attachment section of the housing including a swing axis section, whereas the distance sensor including a swing support holding the swing axis section,
• the swing support having a center vertically upward of a center of gravity of the distance sensor,
• the swing axis section protruding upward and having a gradually smaller diameter toward an upper end thereof, and
• the swing support being a depressed surface section open downward and in contact with the upper end of the swing axis section.
