Claims

[Scope of Claim for Utility Model Registration] A sensor housing having a removably attached outer cover with an inlet for smoke, gas, etc. generated by a fire, and the outer cover is fitted to the sensor housing by turning it. In a fire detector that is attached to the outer cover and forms a hidden detection chamber inside, an engaging claw is formed on one of the fitting portions of the outer cover and the sensor housing, and an engaging claw is formed on the other side. A locking mechanism is formed between the outer cover and the sensor housing to form an engaging protrusion that fits together, and to engage each other when the engaging claw and the retaining protrusion are engaged, and to release the engagement by a release operation using a jig. A fire detector characterized in that it is provided inside surrounded by and at a position opposite to the inlet.
