Method of producing seat reclining apparatus

A method of producing a seat reclining apparatus which enables an angle of a seatback of a reclining seat relative to a seat cushion of said reclining seat to be adjusted, said seat reclining apparatus including a base member which is provided on one of said seat cushion and said seatback;

• a ratchet which is provided on the other of said seat cushion and said seatback and allowed to rotate relative to said base member and has a meshing portion;
• a lock member which is supported by said base member so as to be movable between an engaged position, in which said lock member is engaged with said meshing portion of said ratchet, and a disengaged position, in which said lock member is disengaged from said meshing portion of said ratchet;
• a lock drive member configured to operate selectively in a locking direction to move said lock member to said engaged position and an unlocking direction to move said lock member to said disengaged position in accordance with rotation of a rotational shaft member;
• and a biasing member which includes a first connecting portion and a second connecting portion which are fixed to said base member and said lock drive member, respectively, and biases said lock drive member in said locking direction in a biasing state in which said first connecting portion and said second connecting portion are fixed to said base member and said lock drive member, respectively, wherein said angle of said seatback relative to said seat cushion varies by rotation of said ratchet relative to said base member, and said method of producing a seat reclining apparatus comprising:
• connecting one of said first connecting portion and said second connecting portion to associated one of said base member and said lock drive member, with said lock member and said lock drive member supported on said base member, thereby bringing said biasing member to a temporarily held state;
• mounting said ratchet to said base member so as to cover said biasing member in said temporarily held state;
• and
• fixing the other of said first connecting portion and said second connecting portion to the other of said base member and said lock drive member through an opening which is formed in one of said base member and said ratchet, thereby bringing said biasing member to said biasing state from said temporarily held state.
