Claims

[Scope of utility model registration request]

A case has a drawer opening for pulling out the rules wound and stored in the case, and a tongue-shaped pressure welding piece made of an elastic material is slidably disposed in the drawer opening of the case so as to intersect with the rule, and the pressure welding piece is The tips of the support rods extending left and right are fitted into support slits in the case body, and above the drawer opening there is provided a push button whose central part is pivoted in a seesaw style, and at the lower end of the push button is an L.
A locking portion protruding in the shape of a letter is provided, the lower surface of the locking portion of the push button is a cam surface, the cam surface is provided with a first cam surface and a second cam surface, and the first cam surface and the seesaw type are provided. The cam surface has a distance from the fulcrum of the push button that is larger than the distance between the second cam surface and the fulcrum of the seesaw type push button,
When the cam surface and the top of the pressure contact piece are in contact with each other, and the lower end of the push button is pushed into the case, the pressure contact piece releases the pressure contact with the rule, and when the upper end of the push button is pushed into the case, the pressure contact piece releases the pressure contact with the rule. A tape measure in which the support rod of the pressure welding piece is deformed so that the pressure welding piece and the rule are brought into pressure contact.
