PURPOSE: To find a fork with a simple structure by a simple method, provided with two legs and oscillatable head portion between two legs.
CONSTITUTION: Cutouts 3, 17 starting from a free end and extending into legs 7, 14 of a fork 1 are provided on the legs 7, 14 and extend in a longitudinal axis of the legs 7, 14. An end portion range terminating at the legs 7, 14 is formed to a semi-circular shape. A wall separating the end portion range of a semi-circular shape is used as a support surface of a shaft-like member 5. The shaft-like member 5 is mounted to a constitutional member 2 or forms a structure unit body with the constitutional member 2. The shaft-like member 5 is provided on the constitutional member 2 at a right angle against a longitudinal axis of the fork 1 and is found to the fork 1. The constitutional member 2 extending into a slit 8 of the fork 1 and the fork 1 are relatively oscillatable each other around a longitudinal axis of the shaft-like member 5. A free end range of the shaft-like member 5 is supported by cutouts 6, 15 at a side portion of spring elements 4, 16, 13. According to the above constitution, a joint can be found with a simple structure by a simple method.
