Title:
DRIVING TYPE ANCHOR
Document Type and Number:
Japanese Patent JP2003222111
Kind Code:
A
Abstract:

To provide a driving type anchor which has strong resistance force against withdrawal from a prepared hole and prevents the head from making partial contact with a member.

When forming a curved part 5 between the first straight line part 3 and the second straight line part 4, while making a following part 5b to the head 2 steeper than the top 5a, the slope of the advancing part 5c is made gentler than that of the top 5a. Driving can be carried out smoothly by the guide action in the advancing part 5c, which leads to improvement of the withdrawal resistance. It is desirable to form a notch 9 in the part abutted on the prepared hole 8.
