Claims

[Scope of Claim for Utility Model Registration] 1. In a vehicle negative pressure booster in which the booster shell is equipped with an L-shaped vacuum connector for connecting a negative pressure conduit, a connector holding pipe communicating with the negative pressure introduction hole of the booster shell, A positioning protrusion is provided to protrude outside the booster shell, and is provided on either the protrusion of the connector holding tube or the mounting side pipe portion of the vacuum connector so that the vacuum connector can be attached in any direction relative to the booster shell. and a positioning recess is formed on the other side, and a plurality of at least one of the positioning protrusion and the positioning recess are formed, and the positioning protrusion and the positioning recess are engaged with each other in a concave and convex manner to attach the vacuum connector to the connector holding tube. A mounting structure for a vacuum connector in a negative pressure booster for a vehicle, characterized in that the connector is removably fitted and is prevented from coming off by a fixing means such as a fastening band. 2. In a negative pressure booster for a vehicle in which a booster shell is provided with an L-shaped vacuum connector for connecting a negative pressure conduit, the vacuum connector is formed in the booster shell so that the vacuum connector can be attached in any direction relative to the booster shell. A positioning protrusion is formed on one of the negative pressure introduction hole and the vacuum connector, and a positioning recess is formed on the other, and at least one of the positioning protrusion and the positioning recess is plural, and the positioning protrusion and a positioning recess are recessed and recessed to removably fit the vacuum connector into the negative pressure introduction hole, and these are prevented from being removed by a fixing means such as a fastening band. Installation structure of vacuum connector in power equipment.
