摘要： PROBLEM TO BE SOLVED: To operate a vacuum cleaner, regardless of the direction of a suction port main body, by providing the lower surface of the suction port main body with a horizontally moving wheel rolling in a substantially horizontal direction so that the moving wheel may freely appear and disappear and setting a wheel appearing and disappearing mechanism so as to protrude the horizontally moving wheel from the lower surface of the suction port main body as a casing is rotated upward. SOLUTION: A suction port main body is constituted of a lower case and an upper case which are divided into two in the vertical direction at the rough center height location and form an external case and a wheel 123 for moving in the horizontal direction is provided with a pair of wheel bases 120 journalled at an almost right angle to a roller 132 receiving pressure on a cleaning surface at both the sides of a casing of the lower case so that the wheel bases 120 may freely appear and disappear. When each wheel base 120 is normally energized upward by a spring and the casing of the lower case is rotated upward around a horizontally rotary shaft, each wheel base 120 is protruded to the lower surface of the lower case, the roller 132 is made apart from a floor surface and the horizontally moving of the suction main body is made possible by pressing each wheel base 120 by a wheel appearing and disappearing protrusion provided within the casing.

摘要： PROBLEM TO BE SOLVED: To obtain excellent sucking performance as against dust in the edge of a wall, etc., without exchange into an exclusive sucking mouth for cleaning the edge of the wall, etc., by providing recessed parts on the front surface of the sucking mouth so as to form a gap penetrating from an upper part to a lower part in a state where the sucking mouth front surface is brought into contact with a plane. SOLUTION: The recessed parts 103, 104 and 105 are provided in the front part of a bumper 102 which is pinched between a lower case 101 provided with a floor surface opening 121 facing a cleaned surface and an upper case, fixed and held by the sucking mouth so as to be pinched by a sucking mouth cover. Besides, the recessed parts 108 and 110 are provided in the front part of the base surface of the lower case 101 and projections 107 and 109 are provided in a center. Moreover, a flexible member 106 consisting of an elastic body and a notched part (notch) are provided in the lower case 101, a projecting part being a part without the notch is projected downward from the base surface of the lower case 101 and it is brought into contact with a wooden floor when the sucking mouth is used on a floor being hard without sinking such as the wooden floor.

摘要： PROBLEM TO BE SOLVED: To improve operability when a suction port main body is moved in the lateral direction by arranging a wheel which projects downward from the suction port main body by a movement of a connecting tube and rotates in the direction different from the advancing direction of the suction port main body, under the suction port main body. SOLUTION: In a lower case in a suction port main body, a pair of wheel stands 120 where a lateral directionally moving wheel 123 is journalled at an almost right angle to a roller 132, are journalled to both sides of a casing so as to be capable of protruding/retreating. These wheel stands 120 are energized upward by a spring 175, and when the casing rotates upward around a horizontal rotary shaft by a wheel protruding/retreating projection 176 arranged in the casing, the wheel stands 120 are pushed, and project to a lower case under surface, and when the casing rotates up to the uppermost part, the roller 132 is constituted so as to float from a floor surface. Therefore, the lateral directionally moving wheel 123 journalled at an almost right angle to the roller 132 is grounded, and excellent traveling performance when moved in the lateral direction, can be secured.

摘要： PROBLEM TO BE SOLVED: To enable even a vacuum cleaner of such a type that its intake joint is rotatable vertically and in the circumferential direction of a joint pipe to be constructed while guaranteeing free rotation of them, without exposing wiring of this joint part to the outside, and prevent damage to the wiring on contact with obstacles during cleaning. SOLUTION: A connection 47 for connection to a feeder laid in an extension pipe and a lead wire 48 for electrical connection to the connection are placed on the outer peripheral surface of the bent joint 6 of a vacuum cleaner, and at least a part of the connection 47 and the lead wire 48 are covered with a protective cover 49 so that they are not exposed to the outside. In order to make an electrical connection with the motor of an intake main body 1 from the connection 47, the lead wire 48 leads to an electrical part provided inside the intake main body 1, and is connected while having a sag that permits the rotation of the bent joint 6 in the circumferential direction.
