Claims

[Claims for Utility Model Registration] A thread tension stand 13 fixed to the frame 10 of the sewing machine, a thread tension shaft 15 whose base end is supported by the thread tension stand 13, and a thread tension shaft 15 fitted into the thread tension shaft 15. a pair of thread tension discs 20; a thread tension spring 21 for applying thread clamping pressure to the two pairs of thread tension discs 20; - the thread tension shaft 15 for adjusting the thread clamping pressure of the thread tension springs 21; an operating knob 26 rotatably supported on the free end of the thread tension shaft 15; a thread loosening pin 23 that is slidably inserted into the thread tension shaft 15 to release the thread clamping pressure;
a rotating shaft 29 disposed parallel to the thread tension shaft 15 in an area inside the outer periphery of the thread tension stand 13 and rotatably supported by the thread tension stand 13; a first power transmission means 26a, 30 for interlocking the knob 26; A movable instruction section 32b that cooperates with the stationary instruction section 33 to display the operation amount of the operation knob 26.
an indicating member 32 provided with a second power transmitting means 31, 32a for interlocking the indicating member 32 and the rotation shaft 29, and the first and second power transmitting means 26a, 30. At least one of 31 and 32a is a deceleration mechanism, and the rotation of the operation knob 26 is transmitted to the instruction member 32 at a reduced speed;
An engaging portion 20a' with the rotating shaft 29 is formed around the pair of thread tension discs 20, thereby preventing the pair of thread tension discs 20 from rotating. Features a sewing machine thread tension device.
