Abstract
One object of the invention is to provide a plug cap that more reliably prevents the leakage of current by suppressing the ingress of water from a gap between a terminal body and a rubber member.
A plug cap 1 includes an electrical connection portion 5 that electrically connects a spark plug to a plug cord, a terminal body 2 that is provided on the outer periphery of the electrical connection portion 5, and a cylindrical rubber member 3 which is mounted on at least one of one end portion and the other end portion of the terminal body 2 and into which the spark plug or the like is inserted. The terminal body 2 includes a one end-side insertion portion 41 which is formed at one end of the terminal body and into which the spark plug is inserted and the other end-side insertion portion 42 which is formed at the other end of the terminal body and into which the plug cord is inserted. The rubber member 3 includes an inner cylindrical portion 31 that is inserted into the one end-side insertion portion 41 or the other end-side insertion portion 42, and a cylindrical outer cylindrical portion 32 that is positioned close to the outer periphery of the inner cylindrical portion 31. The inner cylindrical portion 31 includes annular protrusions 35 that come into contact with the inner peripheral surface of the terminal body 2.

7. A plug cap comprising:
-
an electrical connection portion that electrically connects a spark plug to a plug cord, the spark plug being connected to one end of the electrical connection portion and the plug cord being connected to the other end of the electrical connection portion; a terminal body that is made of a resin, is provided on an outer periphery of the electrical connection portion, and includes a one end-side insertion portion which is formed at one end of the terminal body and into which the spark plug is inserted and the other end-side insertion portion which is formed at the other end of the terminal body and into which the plug cord is inserted, at least the one end-side insertion portion and the other end-side insertion portion being formed in a cylindrical shape; and a cylindrical rubber member which is mounted on at least one of one end portion and the other end portion of the terminal body and into which the spark plug or the plug cord is inserted, wherein the rubber member includes a cylindrical inner cylindrical portion that is inserted into the one end-side insertion portion or the other end-side insertion portion of the terminal body, a cylindrical outer cylindrical portion that is positioned close to the outer periphery of the inner cylindrical portion and is disposed with the terminal body interposed between the outer cylindrical portion and the inner cylindrical portion, and a connecting portion that connects the outer cylindrical portion to the inner cylindrical portion, and the inner cylindrical portion includes an annular protrusion that comes into contact with the inner peripheral surface of the terminal body. - View Dependent Claims (8, 9, 10, 11, 12)
