<p>The present invention relates to a seat clamp. A tightening bolt (13) which penetrates through each part of the seat clamp and is operated by a specific tool to fix a seat post (5) on a seat tube (3) of a bicycle frame (1). As the tightening bolt (13) is tightened by the specific tool, a gap between a guide slope (24) of a clamp body (20) and a wedge member (40) becomes narrow and a pressing rod (30), which is placed between a clamp body and the wedge member (40), applies pressure on the seat post (5) while coming in close contact with the seat post. Accordingly, the seat clamp is not operated by a user who does not have the specific tool since the user who uses a tool different from the specific tool has difficulty in releasing the fixed state of the seat post (5) on the seat tube (3), thereby preventing theft of a seat (7) and having advantages of being applied to various shapes of seat tubes for use.</p> |
