Claim:
1. An electric parking brake device configured to move a parking lever in a drum brake from a return position to an actuating position by forward driving of an electric actuator, moving a brake shoe from the return position to the actuating position, and to move the parking lever from the actuating position to the return position by backward driving of the electric actuator, moving the brake shoe from the actuating position to the return position, wherein the electric actuator includes an electric motor capable of rotating forward and backward, a conversion mechanism capable of converting rotational motion of the electric motor into linear motion of a shaft member, and a connection mechanism that connects an end of the shaft member to a swinging end of the parking lever, and the connection mechanism includes a first connection pin that is fitted in an end of the shaft member, is orthogonal to the shaft member, and is disposed parallel to a support shaft of the parking lever, a second connection pin that is fitted in a swinging end of the parking lever and is disposed parallel to the first connection pin, and a connection member that is rotatable with respect to an end of the shaft member in a circumferential direction of the first connection pin at a first hole where the connection member is fitted on the first connection pin, is rotatable with respect to the parking lever in a circumferential direction of the second connection pin at a second hole where the connection member is fitted on the second connection pin, and connects the first connection pin to the second connection pin.
