Abstract: The present invention relates to an accessory tool for a vacuum cleaner by which a small crevice can be easily cleaned and exchange of accessory tools depending on places to be cleaned can be simplified. In the accessory tool of the present invention, an inlet 62 with a plurality of suction tubes 64 made of a flexible material is provided at a front portion of an octopus-leg like tool 60 for use in suction of dirt in a small crevice. Further, a brush 66 is provided along a periphery of each of the suction tubes 64. A coupling portion 68 is formed in the rear of the inlet 62 to communicate therewith. The coupling portion 68 is detachably coupled with an inlet 72 formed at a front portion of a brush tool 70, and a brush 74 is provided along a periphery of the inlet 72. A connecting portion 76 is formed in the rear of the inlet 72 to be connected to an end of an extension tube of the vacuum cleaner and to communicate with the inlet 72.

Abstract: The present invention relates to a caster for a vacuum cleaner. The caster of the present invention is installed at and rotatably supported on a front portion of a bottom surface 40 of a main body of the vacuum cleaner. The caster comprises a caster body 52 protruding from the bottom surface to be rotatably supported on a horizontal plane and having a planar rear surface 54 with a predetermined width; and a caster roller 56 rotatably installed on a bottom surface of the caster body 52. The rear surface of the caster body 52 is formed with a slip-prevention protrusion 58 extending in a right and left direction. The caster 50 is in pairs in a right and left direction on the bottom surface 40 of the main body of the vacuum cleaner.

Abstract: The present invention relates to a motor housing to be installed within a main body of a vacuum cleaner. The motor housing according to the present invention is installed within the main body of the vacuum cleaner including a dust collection unit capable of filtering out foreign substances. The motor housing comprises a casing 210 of which an upper portion is open; a cover 212 hingedly coupled to a side of the casing for opening and closing the casing; a fastening means for maintaining a state where the cover closes the casing; a suction portion 220 which is formed at a side surface of the casing and through which air can be introduced from the dust collection unit into the motor housing; and an exhaust portion 222 which is formed at the other side surface of the casing and through which the air introduced in the motor housing can be exhausted to the exterior.
