1. A cover device that is configured to cover a motor terminal of an electric motor and electrically connect the motor terminal to an external device, the cover device comprising:
a terminal receiving portion that is in a form of a recess and has a plurality of inner peripheral surfaces, wherein the terminal receiving portion is configured such that the motor terminal is insertable into the terminal receiving portion, and a conductive member, which is configured to be electrically connected to the external device, is exposed at one or more of the plurality of inner peripheral surfaces; and
a terminal member that is flexible and is formed by a bent metal plate, wherein the terminal member is received in the terminal receiving portion and is configured to contact a portion of the conductive member exposed at the one or more of the plurality of inner peripheral surfaces, and the terminal member comes into pressure contact with the motor terminal when the motor terminal is inserted into the terminal receiving portion, wherein:
the terminal member includes:
a first wall that is arranged along a first inner peripheral surface, which is one of the one or more of the plurality of inner peripheral surfaces at which the conductive member is exposed;
a second wall that is arranged along a second inner peripheral surface which is opposed to the first inner peripheral surface;
a third wall that connects between one end portion of the first wall, which is directed in an inserting direction of the motor terminal into the terminal receiving portion, and one end portion of the second wall, which is directed in the inserting direction of the motor terminal; and
a pressure-contact portion that is configured to urge the motor terminal against the first wall, wherein the pressure-contact portion is joined to another end portion of the second wall, which is directed in an opposite direction being opposite to the inserting direction, and the pressure-contact portion is shaped to be bent from the second wall such that the pressure-contact portion progressively approaches toward the first wall away from the second wall until a turning point and then progressively approaches back toward the second wall away from the first wall as the pressure-contact portion extends in the inserting direction;
a length of the third wall, which is measured in a direction directed from a first connection between the first wall and the third wall to a second connection between the second wall and the third wall, is longer than a distance between the first connection and the second inner peripheral surface and is longer than a length between the second connection and the first inner peripheral surface;
the second connection is placed on a side of the first connection which is opposite to the press-contact portion in the inserting direction;
an angle between the first wall and the third wall is an obtuse angle, and an angle between the second wall and the third wall is an acute angle; and
the second connection is configured to be urged against the second inner peripheral surface to limit movement of the second wall in the opposite direction when the second wall is vibrated.
