摘要： PROBLEM TO BE SOLVED: To provide a vehicular front grill capable of appropriately reduces noise generated by a direct-injection engine over a wide band.
SOLUTION: This vehicular front grill is dually structured including first and second grills comprising a plurality of bar-like members. Specifically, the first grill is located toward the outside of a vehicle relative to the second grille, and the second grill is located toward an engine compartment relative to the first grill. Thus, noise in the engine compartment is effectively suppressed from being directly emitted toward the outside of the vehicle. Moreover, noise emitted from the engine compartment can be made to enter in the first and second grills at a plurality of times. Accordingly, the front grill can appropriately reduce noise over the wide band range.

摘要： PROBLEM TO BE SOLVED: To provide a positioning tool and a positioning method for a work capable of enhancing measuring precision by simplifying structure.
SOLUTION: An inner clamper 61 is attached to an upper end part W1 of the work W set by engaging six vertical ball grooves 10 on an inner circumferential face respectively with six phase guides 7 arranged on a measuring block. A pin 64 is slid circumferentially because an inclined part 62 of a clamper 11 goes down while abutting to the pin 64 of the inner clamper 61, when the clamper 11 is inserted into the inner clamper 61, and the inner clamper 61 and the work W are rotated. The work W is not fluctuated circumferentially during measurement to enhance the measuring precision, because one end of each of the vertical ball grooves 10 contacts with the corresponding phase guide 7 to fix the work W positionedly along a circumferential direction.
