Connection structure of electric component, motor and connection method of electric component

A connection method of an electric component which uses:

• an electric component main body having a connection terminal,
• a connector which is connected with the connection terminal,
• a base member comprising an accommodation recessed part having an opening part opened to an upper side, and
• a cover member,
• wherein the cover member has an upper side circular arc face,
• the base member has a lower side circular arc face at a position facing the upper side circular arc face,
• the upper side circular arc face and the lower side circular arc face contact each other,
• the connection method comprising:
• a disposing process, in which the base member is disposed so that a connected portion between the connection terminal and the connector is accommodated in the accommodation recessed part of the base member;
• a filling process, in which a sealing material is filled in an inside of the accommodation recessed part so as to seal the connected portion between the connection terminal and the connector;
• an attaching process, in which the cover member is attached to the base member so as to cover the opening part of the accommodation recessed part and contact with the sealing material;
• and
• a hardening process, in which the sealing material is hardened to fix the connected portion between the connection terminal and the connector, the base member, and the cover member to each other.
