PROBLEM TO BE SOLVED: To lock a rotary pipe and a suction port main body by a simple structure by providing an energizing means with a locking part for locking the rotary pipe at the turned position when the rotary pipe is rotated for a prescribed angle to the suction port main body. SOLUTION: Within the turning range of the rotary pipe 80, that is in the state of not erecting the rotary pipe 80, the pin 85 of the rotary pipe 80 is positioned on the right side of the projection part 69 of a twist spring 68, the rotary pipe 80 is not locked and the suction port main body 51 is energized to the side of a surface to be cleaned by the twist spring 68 at all times. When the rotary pipe 80 is erected, that is when a cleaner main body is erected to the suction port main body 51, the pin 85 of the rotary pipe 80 goes over the projection part 69 of the twist spring 68 and is locked to the left side of the projection Part 69. By the locking and the abutting of the other projection parts, the rotary pipe 80 is locked at an erected position. By the locking, an electric vacuum cleaner main body 10 is stably housed.
