Title: HOLDING JIG AND PRESSURE LOSS MEASURING APPARATUS
Abstract:
A holing jig (70) has a cylindrical jig base material (50), and a cylindrical stretching member (52), which is provided on the inner circumferential surface side of the cylindrical jig base material (50). Both the end sides of the cylindrical stretching member (52) are fixed to both the end sides of the cylindrical jig base material (50) over the entire circumference. The shape of the inner circumferential surface (62) of the cylindrical stretching member (52) is smaller than the outer shape of a columnar body (honeycomb structural body) (2) to be held. The shape of the inner circumferential surface (60) of the cylindrical jig base material (50) is larger than the outer shape of the columnar body (honeycomb structural body) to be held. With the holding jig (70), even if the honeycomb structural body has a variant shape and the shape accuracy thereof can be easily fluctuated, the honeycomb structural body can be held with excellent airtightness.
