Motorized locking device for opening/shutting unit

An electric lock device for an opening and closing member configured to be openably and closably attached to an opening portion in a fixed member, the electric lock device comprising:

• a lock portion provided on one of the opening and closing member and the fixed member;
• a rod slidably arranged on an other of the opening and closing member and the fixed member and configured to engage with and disengage from the lock portion;
• a biasing member configured to directly or indirectly bias the rod in a direction in which the rod is brought into engagement with the lock portion;
• and
• an actuator arranged on the other of the opening and closing member and the fixed member and configured to slide the rod to disengage from the lock portion, wherein
• the actuator includes a case attached to the other of the opening and closing member and the fixed member, a motor arranged within the case, a wheel configured to rotate in conjunction with the motor, and a rotor rotatably supported within the case and configured to engage with the rod and to cause the rod to engage with and disengage from the lock portion by a rotation operation,
• the wheel is provided with a pressing portion that is configured to engage with a receiving portion provided on the rotor or the rod when the wheel rotates in a predetermined direction to move the rod against a biasing force of the biasing member in a direction in which the rod disengages from the lock portion,
• when a rotation force is applied to the rotor in a direction against the biasing force of the biasing member via the rod in a state where the rod is biased by the biasing member in a direction in which the rod is engaged with the lock portion, the rotor is capable of rotating independently of the wheel in a direction in which the receiving portion is separated from the pressing portion,
• a gear is provided on a drive shaft of the motor,
• the case includes a cylindrical wall,
• the wheel includes a peripheral wall in which teeth that mesh with the gear are formed,
• the peripheral wall of the wheel is arranged inside or outside the cylindrical wall, and the wheel is rotatably supported, and
• on one of the cylindrical wall and the peripheral wall,
• an axial notch formed in an opposite portion where the cylindrical wall and the peripheral wall face each other in an axis direction of the cylindrical wall and the peripheral wall and/or a radial concave portion formed in an opposite surface where the cylindrical wall and the peripheral wall face each other in a radial direction of the cylindrical wall and the peripheral wall are provided, and a non-contact surface in which the cylindrical wall and the peripheral wall are not in contact with each other is partially provided.

• the wheel includes a base portion, and a peripheral wall extending from a peripheral edge of the base portion, and
• the pressing portion is arranged inside the peripheral wall.
