Abstract
It is an object of the invention to provide an effective technique to improve ease of use in adjustment of the bevel angle of a circular saw body of a circular saw. The representative portable circular saw that includes a base, a circular blade, a circular saw body, a pivot, a locking device and a restricting arrangement. The locking device is manually operated by a user to lock the circular saw body to the base in a desired bevel angle position. Besides the locking device, the restricting arrangement prevents free pivotal movement of the circular saw body by holding the circular saw body at a predetermined common bevel angle position. In order to cope with cutting operations both at any desired bevel angle and at the predetermined common bevel angle, the engaging member can be selectively moved between the restricted position in which the engaging member is allowed to contact the engagement portion for allowing the common bevel angle setting and an unrestricted position in which the engaging member is not allowed to contact the engagement portion for allowing the free bevel angle setting by the user without being interfered by the common bevel angle setting arrangement.
