Claims

[Scope of utility model registration request]

A cylindrical support body having an inner circumferential surface that loosely fits around the outer periphery of the body of the stepping motor and a fixed portion, and a gel-like substance, the gel-like substance being attached to the inner circumferential surface of the cylindrical support body and the stepping motor. It is interposed between the outer periphery of the body of the motor and connects the two in a vibration-absorbing manner, and the fixed part of the cylindrical support is fixed to the mounting part on the equipment side.
A mounting structure for a stepping motor, characterized in that the stepping motor is supported for slight angle rotation around its output shaft.
