    摘要： Provided is a butterfly valve-type throttle valve of an internal combustion engine capable of absorbing a dispersion in valve opening degree at closed positions to reduce a leakage of air by solving problems, for example, with a multi-arrayed variable intake valve device in which a plurality of throttle valves mounted on a single turning shaft are opened and closed, a dispersion in valve opening degree is liable to occur at the closed positions due to the mounting errors of the throttle valves on the turning shaft and, accordingly, it is difficult to reduce the leakage of air. A clearance closing member (12) is supported in a floating state along a peripheral edge of a valve body (11) and displaced or elastically deformed to eliminate or reduce a clearance between the clearance closing member and an inner wall surface (2a) of an intake passage.

    摘要： A throttle valve comprising a first outer peripheral portion linearly contacting an inner wall of an intake passage at a predetermined throttle angle and a second outer peripheral portion formed in the vicinity of a throttle shaft in such a manner as to gently continue from the first outer peripheral portion and not contacting the inner wall at the predetermined throttle angle. With this arrangement, as there is defined a space between the second outer peripheral portion and the inner wall in the vicinity of the throttle shaft, the generation of scuffing and biting of the throttle valve against the inner wall may be prevented. Further, as the first outer peripheral portion of the throttle valve linearly contacts the inner wall at the closing position, the leakage of suction air upon full closing of the throttle valve may be suppressed. Further, a drainage structure for a motor for opening and closing the throttle valve and a bearing support structure for rotatably supporting the throttle shaft with respect to a throttle housing are also disclosed.

    摘要： A method is provided for diffusion bonding a first member (20) and a second member (3) to each other. According to this method, a first joint portion (24) of the first member and a second joint portion (34) of the second member are fitted to each other with a predetermined interference. Thereafter, the first and second members are heated under a condition substantially without oxygen, so that the first and second joint portions are diffusion bonded to each other.
