シヨンロツク機構。[Claims for Utility Model Registration] A webbing take-up reel rotatably supported by a base, a take-up spring that biases the take-up reel in the webbing take-up direction, and a take-up spring integrally formed on the take-up reel. a latch position that engages with the ratchet member to prevent rotation of the take-up reel in the webbing winding direction; and a non-latched position that does not engage the ratchet member and allows rotation of the take-up reel. the latch member is controlled to move between the latched position and the unlatched position as the webbing is drawn out and retracted so that the latching member returns to the latched position after a predetermined series of webbing attachment operations; and second control means for sensing a predetermined webbing undocking motion and forcing the latch member to an unlatched position, wherein the latch member is in contact with the first biasing means. The second control means includes a solenoid that is energized by a predetermined webbing attachment operation and deenergized by the predetermined webbing unattachment operation; a plunger that assumes a first position to allow the latch member to assume the latched position under force from the solenoid and assumes a second position to cause the latch member to assume the unlatched position when the solenoid is de-energized; a second biasing means for biasing the plunger toward a second position; the biasing force of the first biasing means acts on the plunger until after the predetermined series of webbing attachment operations are completed; an auxiliary means for applying an auxiliary force to bring the plunger into position; respectively f 1 , f 2 , f 3
A tension lock mechanism for a retractor, characterized in that the following relationship is satisfied: f 1 +f 2 >f 3 >f 1 , f 2 .
