<P>PROBLEM TO BE SOLVED: To provide a component connection structure of a writing utensil, wherein a joining component can be firmly stuck to a target component to be joined. <P>SOLUTION: In the insertion part of a joining component, there are formed a small diameter part that becomes a tip end side in the inserting direction into a target component and a large diameter part that is situated to the rear of the small diameter part. Also, in the insertion receiving part of the target component, there are formed a small hole and a large hole that fit, with a minute gap, to the small diameter part and the large diameter part in the insertion part of the joining component. When the insertion part of the joining component is inserted into the insertion receiving part of the target component, a first adhesive layer is formed between the small diameter part of the joining component and the small hole of the target component and, likewise, a second adhesive layer is formed between the large diameter part of the joining component and the large hole of the target component, with the components made to stick to each other. <P>COPYRIGHT: (C)2009,JPO&INPIT |
