Claims

[Scope of Claim for Utility Model Registration] (1) A pin for screwing the blade fitting onto either one of the base or the sensor body; at least one of the blade fitting attachment part of the base and the blade fitting. A fire detector comprising: a means for preventing rotation of a blade metal fitting provided at the pin; and a soldering part for fixing the tip of the pin and a conductive part. (2) A blade attachment part provided on the back of the base of the sensor body; a printed circuit board placed on a protrusion provided on the inner surface of the base; and a blade attachment part installed on the blade attachment part. A pin that is screwed and whose tip passes through the protrusion and protrudes from the surface of the printed circuit board; a soldered portion that fixes the tip of the pin and the printed circuit board; at least a blade fitting mounting portion or a blade fitting. A fire detector comprising: a means for preventing rotation of a blade metal fitting formed on either side; (3) The fire detector according to claim 1 or 2, wherein the pin is provided with a threaded portion. (4) The fire detector according to claim 1 or 2, wherein the rotation prevention means is a regulating wall formed on the blade attachment portion. (5) The fire detector according to claim 1 or 2, wherein the rotation prevention means is a vertical claw fitted into the blade attachment part. (6) The fire detector according to claim 5, wherein the vertical claw is formed at the tip of the fixed portion of the blade metal fitting. (7) The fire detector according to claim 5, wherein the vertical claw is formed on the side edge of the fixed portion of the blade metal fitting.
