What is claimed is: 1. A power blower, comprising: a frame; a blower spaced apart from said frame by an air intake space, and having an air intake port facing said frame; and a debris-catching cover constructed between said frame and said blower with said debris-catching cover mounted on both the frame and blower sides, and said debris-catching cover configured to inhibit debris from being sucked from said air intake space into said air intake port, wherein the debris-catching cover includes a substantially quadrangular tabular portion having a circular opening with a diameter larger than that of the air intake port at a central portion thereof, a top wall, right and left side walls, and a skirt portion, and wherein each of the top wall, the right and left side walls and the skirt portion includes debris screens. 2. The power blower according to claim 1, wherein said debris-catching cover is mounted on a case of said blower around said air intake port, and wherein said debris-catching cover is mounted on said frame at positions along the longitudinal edges on the left and right sides of said frame. 3. The power blower according to claim 1, wherein said debris-catching cover has a debris screen at a position spaced radially outward apart from said air intake port. 4. The power blower according to claim 3, wherein said debris-catching cover comprises debris screen portions facing up, down, left, and right with respect to said air intake space. 5. The power blower according to claim 1, wherein said debris-catching cover is formed of a material having a good vibration-absorbing property. 6. The power blower according to claim 1, wherein said debris-catching cover is securely fixed with respect to said blower, and wherein said debris-catching cover is mounted with respect to said frame with clearances of a predetermined size for preventing passage of debris. 7. The power blower according to claim 1, wherein each of the mounting portions of said debris-catching cover with respect to said frame and said blower is formed in an ear shape. 8. The power blower according to claim 1, wherein said debris-catching cover defines a plurality of slits for preventing passage of debris, and for reducing the amount of vibration transmission between said blower and said frame through said debris-catching cover. 9. A debris-catching cover constructed between a frame and a blower that is spaced apart from said frame by an air intake space, that has an air intake port facing said frame, and that inhibits debris from being sucked from said air intake space into said air intake port, said debris-catching cover comprising: frame-side mounting portions for mounting said debris-catching cover to said frame; blower-side mounting portions for mounting said debris-catching cover to said blower, the debris-catching cover including a substantially quadrangular tabular portion having a circular opening with a diameter larger than that of the air intake port at a central portion thereof, and a top wall, a left and right side wall and a skirt portion, each of which includes a debris screen. 10. The debris-catching cover according to claim 9, wherein said blower-side mounting portions are formed at positions around said air intake port, and wherein said frame-side mounting portions are formed at positions along the longitudinal edges on the left and right sides of said frame. 11. The debris-catching cover according to claim 10, further comprising a debris screen at a position spaced radially outward apart from said air intake port, said debris-catching cover mounted by said frame-side mounting portion and said blower-side mounting portion. 12. The debris-catching cover according to claim 11, wherein said debris screen comprises a portion facing up, down, left, and right with respect to said air intake space. 13. The debris-catching cover according to claim 9, wherein the whole of said debris-catching cover is formed of a material having a good vibration-absorbing property. 14. The debris-catching cover according to claim 9, wherein said frame-side mounting portions and said blower-side mounting portions are each formed in an ear shape. 15. The debris-catching cover according to claim 9, further comprising slits for presenting passage of debris, and for reducing the amount of vibration transmission between said blower and said frame through said debris-catching cover. 16. A debris-catching cover configured to be mounted between a blower having an air intake port and a frame of a power blower, comprising: a substantially quadrangular tabular portion having a circular opening with a diameter larger than that of the air intake port at a central portion thereof, a top wall, a right and left side walls, and a skirt portion; a plurality of screen portions positioned on the top wall, the right and left side walls and the skirt portion of said cover for preventing debris passage into a space created between said blower and said frame, said space in fluid communication with the air intake port of said blower, said screen portions allowing passage of air into said space. 17. The debris-catching cover according to claim 16, wherein during operation of the power blower, the velocity of air passing through any single screen portion is less than the velocity of air flowing into said intake port. 18. The debris-catching cover according to claim 16, wherein when said debris-catching cover is mounted on said power blower, said cover comprises screen portions facing up, down, left, and right with respect to said air intake port. 19. The debris-catching cover according to claim 16, wherein said cover is made of a material having a good vibration-absorbing property.
