持装置。 Ball bearings that support rotary supports on both sides of the shaft to which the throttle valve installed in the engine intake passage is fixed are arranged in an annular space formed around the rotary supports in the body of the throttle chamber. In a throttle valve support device for an internal combustion engine, the inner ring of the ball bearing is press-fitted and fixed to the shaft, and the ball bearing is fixedly held by a retainer that is press-fitted in the annular space and is a presser in the thrust direction. By integrally forming a cylindrical part that covers the outer peripheral surface of the ball bearing on the retainer, and crimping the tip of the cylindrical part to engage the outer ring of the ball bearing,
A throttle valve support device for an internal combustion engine, characterized in that a retainer and a ball bearing are fixed.
