PROBLEM TO BE SOLVED: To further appropriately recognize abnormality of electrical wiring connected to a contact point that opens and closes according to occurrence of a predetermined event.SOLUTION: An opening and closing device comprises: an opening and closing body 10 capable of performing closing operation; a contact point 13a provided so as to open and close according to occurrence of a predetermined event; and a control section 60 electrically wired to the contact point 13a. The opening and closing device configured such that the control section 60 performs predetermined control in response to opening/closing of the contact point 13a further comprises: a first resistor 13b electrically wired between the contact point 13a and the control section 60 so as to be connected to the contact point 13a in parallel; and a second resistor 13c electrically wired between the contact point 13a and the control section 60 so as to be connected to the contact point 13a in series. The control section 60 comprises resistance measurement means 61 for measuring a combined resistance value of the contact point 13a, the first resistor 13b and the second resistor 13c and performs the predetermined control according to the combined resistance value measured by the resistance measurement means. |
