A safety device of an elevator capable of suppressing a decrease in availability of the elevator. A host node (63) monitors whether a traveling speed of a car (42) reaches an excessive speed level based on a signal from an upper reference position switch (45), a signal from a lower reference position switch (46), and information related to a traveling direction of the car (42). As the excessive speed level, a first speed level and a second speed level are set to the host node (63). The second speed level is a lower level than the first speed level. The host node (63) applies the second speed level to upward traveling of the car (42) in a case where an upper communication failure is detected, and applies the second speed level to downward traveling of the car (42) in a case where a lower communication failure is detected.
