A boot with a bellows interposed between a large-diameter ring and a small-diameter ring is disclosed. In the bellows, the crest which is the closest to the small-diameter ring is made thinner than the other crests. Accordingly, when the boot is mounted on a mechanical shaft joint, the crest closest to the small-diameter ring is folded preferentially, so that the pitches of the other crests are maintained. The other crests are not brought into contact with each other during the cross movement of the mechanical shaft joint or even if they come into contact with each other, the contact pressure reduced, and the durability is thereby enhanced.

In a state of separating a front end face of an air injecting nozzle 23 from a worked work W by a predetermined interval h, the air injecting nozzle 23 is moved at a constant speed in an X axis direction, injects air from an injecting hole 27a of a nozzle main body 27 and is moved to pass centers O1, O2 of worked holes Wb, Wc of the work W. A variation in a pressure is measured by a pressure measuring unit 30. X axis coordinates of the centers O1, O2 of the holes Wb, Wc, a hole diameter E and a center interval distance D1 are calculated based on coordinates of center points T1, T2 of inclined portions Ld, Lu of a curve Lx of the pressure relative to the measured X axis coordinate.

An exhaust gas recirculation (EGR) system in an engine system includes an intake passage, an exhaust passage, an EGR passage, a connecting passage and an exhaust gas regulating valve. The exhaust passage is provided with a catalyst and a muffler. The EGR passage is provided with a heat exchanger and an EGR valve. The connecting passage fluidly connects the exhaust passage and the EGR passage. The exhaust gas regulating valve is mounted at a merging portion defined between the exhaust passage and the connecting passage. Based on the opening degree of the exhaust gas regulating valve, the exhaust gas flow is adjustably regulated into recirculating flow into the EGR passage or flow through the exhaust passage. Based on the opening degree of the EGR valve, the recirculated exhaust gas in the EGR passage is adjustably regulated into recirculating flow into the intake passage or flow into the connecting passage after passing through the heat exchanger.
