PURPOSE:To improve the ridigity of a frame in a seal condition regarding a synthetic resin frame supporting a motor and a pump directly coupled with it. CONSTITUTION:An annular rise section is formed on the periphery of the opening section 9 of a frame 1, an annular groove section 12 enclosing the said rise section is formed on the periphery section below a cover 10, slant sections 14, 15 are provided on one of one side of the rise section and the inner face 13 of the facing groove section and angular sections 16, 17 abutting on the said slant section are provided on the other, and a gap 18 between the other face of said rise section and the inner face of the groove section is made the press-fit section of an elastic seal body 19. When the elastic seal body 19 is inserted by pressure into the said gap 18 and the cover 10 is mounted on the frame 1, the angular sections 16, 17 hit the slant sections 14, 15 respectively. Accordingly, the frame 1 is supported by a receptacle bed 20 and the cover 10 is depressed by a supersonic wave oscillation transferring body 21, then the contact section is heated by the supersonic wave oscillation applied to it, and the cover 10 and frame 1 are melted together. |
