Title:
DIAPHRAGM PUMP
Document Type and Number:
Japanese Patent JP3525356
Kind Code:
B2
Abstract:
PURPOSE: To reduce length and to down size a pump by rotatably and directly supporting a collar to a case of a motor.
CONSTITUTION: A collar 14 is fixed to an output shaft 2 of a motor 1, and rotatably supported to a case of the motor 1 through a ball bearing 20. Concretely, a collar 4 is arranged inside an inner ring 22 of the ball bearing 20 whose outer ring 21 is fixed to the case of the motor 1. The collar 4 to be arranged in a case 3 mounted on the motor 1 is then directly mounted on the motor 1. The case 3 requires no space for housing the collar 4, so that a size, particularly longitudinal size is reduced. A further smaller pump is thus obtained.
