Valve system for intake air controller for internal combustion engine and manufacturing the same |
摘要 |
<p>An opening end of a concave portion (20) of a bearing holder (16) is crimped to prevent an outer race (23) of a ball bearing (7) from sliding rearwardly, so that a bearing stop cover in the prior art is not needed to stop the slide-out of the outer race (23). Thus, the number of parts and assembling procedures for an intake air controller are reduced, thereby reducing the manufacturing const thereof. Further, since the bearing stop cover is not needed, the axial length of the bearing holder (16) of a throttle body (6) is shortened, thereby axially compacting the throttle body (6). <IMAGE></p> |
