摘要： PROBLEM TO BE SOLVED: To provide an electric apparatus which supports a motor for relieving temperature rise in a bearing. SOLUTION: A motor 51 is supported by providing an air vent passage 12 at the portion where a bearing housing 54 inwardly formed with a bearing 53 and an elastic body 11 disposed so as to include the bearing housing 54 come into contact with each other, and forming a vent hole 14 on the partition wall of the body 32 through the elastic body 11. Therefore, the cooling effect for the bearing housing 54 by the air can be generated by causing the air to peretrate through the air vent passage after it passes through the vent hole 14, heat temperature rise in the bearing 53 included in it can be relieved. It is thus possible to suppress damages to the motor 51 caused by the temperature rise of the bearing 53.

摘要： PROBLEM TO BE SOLVED: To prevent falling off of a pipe by excess loosening in a pipe assembly whose inner pipe fastening force is variable by moving a fastening pipe screwed on the outer periphery of an outer pipe, equipping a dent part on one of the outer periphery face of the outer pipe or the inner periphery face on the fastening pipe and a protruding part to move in the dent part on the other. SOLUTION: On assembling a flexible extension pipe, when an inner pipe 14 is inserted into an outer pipe 11 and a fastening pipe 15 is turned into the fastening direction, the fastening pipe 15 and a fastening ring 17 are advanced by screwing a male screw part 12 of the outer pipe 11 with a female screw part 16 of the fastening pipe 15 in the arrow mark 20 direction. As the fastening pipe 15 moves forward, an open part 21a of a dent part 21 of the fastening pipe 15 approaches a protruding part 22 of the outer pipe 11 and the protruding part 22 goes into the dent part 21 through the open part 21a. When the fastening pipe 15 is further rotated, the protruding part 22 overpasses the dent part 21 and then the protruding part 22 goes into the dent part 21 equipped in the vicinity to become rotatable within a range where the dent part 21 is equipped. Thus falling off of the inner pipe 14 from the outer pipe 11 can be prevented.
