Claims

[Claims for Utility Model Registration] (1) A mode switching cam with an engagement pin set up in an eccentric position, and a pinch at the tip that is rotatable around a support shaft provided near the mode switching cam. A pinch roller arm provided with a roller, a rotor which is connected to the pinch roller arm and a link arm by the pinch roller arm and the link arm, forms an engagement notch groove for the engagement pin, and has a stopper pin erected on its upper surface, and is coaxial with the rotor. The lock member is supported and has a lock pawl formed at one end that engages with the reel base gear, and a long hole that engages with the stopper pin, and a biasing means that biases the lock member toward the reel base gear, A pinch roller mechanism characterized in that the support shafts of the rotor and the lock member are fitted into oval holes formed in the rotor. (2) Locking of the reel base gear of the lock pawl and its release are performed by pushing the elongated hole wall of the lock member with the movement of the stopper pin as the rotor rotates, and coaxially rotating the lock member. A pinch roller mechanism according to claim 1 of the utility model registration claim.
