Claims

[Scope of utility model registration request]

It has a mounting piece attached to a component mounting base of a tape recorder, and a support piece that presses and supports a predetermined component attached to the component mounting base while the mounting piece is attached to the component mounting base. In a tape recorder equipped with leaf springs,
A substantially cylindrical fitting portion into which a mounting piece of the leaf spring can be inserted is formed on the component mounting base, and the mounting piece of the leaf spring is provided with a relief when the mounting piece is inserted into the fitting portion. A locking portion is formed that bites when the piece is pulled out from the fitting portion, and a long hole is formed in a portion of the fitting portion opposite to the locking portion that is elongated in the insertion direction of the attachment piece of the leaf spring. A leaf spring mounting mechanism for holding down parts of a tape recorder, which is characterized by:
