A plug for a vehicle includes: a body portion; a plurality of insertion portions configured to be inserted into a through-hole provided in a housing; and a flange portion having a notch formed on an outer periphery so as to restrict a rotation of the body portion around an axial center. The insertion portions are formed at two positions opposed to each other across a straight line passing through the notch and the axial center and are provided with retaining lugs engageable with the through-hole.
1. A plug for a vehicle, comprising:
a body portion having a circular-column shape and configured such that one part of the body portion is inserted into a through-hole provided in a housing;
a plurality of insertion portions formed integrally at intervals around an axial center of the body portion so as to extend from one end of the body portion in a direction parallel to the axial center, the plurality of insertion portions being configured to be inserted into the through-hole; and
a flange portion formed integrally with the other part of the body portion, the other part being not inserted into the through-hole, the flange portion having a notch formed on an outer periphery so as to restrict a rotation of the body portion around the axial center by being engaged with a projecting member provided in the housing in a projecting manner toward outside the housing at a position adjacent to the body portion, wherein
the insertion portions include two insertion portions that are respectively formed at two positions opposed to each other across a straight line passing through the notch and the axial center and that are each provided with retaining lugs engageable with the through-hole, and
the insertion portions further include two additional insertion portions that are respectively formed at two positions opposed to each other across the axial center, on the straight line passing through the notch and the axial center, and the two additional insertion portions are not provided with the retaining lugs.
2. The plug according to claim 1 , further comprising:
a hose joint portion formed integrally with the other part of the body portion and configured to communicate an external space outside the housing with a hole portion inside the body portion, the hole portion being configured to communicate with a breather chamber provided in an upper part inside the housing, wherein
the plug is a breather plug.
3. A plug for a vehicle, comprising:
a body portion having a circular-column shape and configured such that one part of the body portion is inserted into a through-hole provided in a housing;
a plurality of insertion portions formed integrally at intervals around an axial center of the body portion so as to extend from one end of the body portion in a direction parallel to the axial center, the plurality of insertion portions being configured to be inserted into the through-hole; and
a flange portion formed integrally with the other part of the body portion, the other part being not inserted into the through-hole, the flange portion having a notch formed on an outer periphery so as to restrict a rotation of the body portion around the axial center by being engaged with a projecting member provided in the housing in a projecting manner toward outside the housing at a position adjacent to the body portion, wherein
the insertion portions include two insertion portions that are respectively formed at two positions opposed to each other across a straight line passing through the notch and the axial center and that are each provided with retaining lugs engageable with the through-hole, and wherein:
the flange portion has a sector shape with an arc smaller than a semicircle; and
the notch is formed in the arc.
4. The plug according to claim 3 , wherein
the notch has an arc shape.
