Abstract
A housing for a magnetic tape cassette has a front opening at which a magnetic tape is exposed and a front lid pivoting on a shaft to close the front opening. The spring which biases the front lid so as to close the front opening has a substantially U-shaped engagement end portion which engages a spring engagement projection extending in a direction substantially parallel to the shaft mounting the front lid so that the spring can be easily and positively attached to the front lid.
